Best experience everI first came here to follow the Open Water course. I enjoyed it so much that I decided to continue with diving courses. 8 months later, I returned to follow the Divemaster program, which is the entry stage of the diving professional world.I was glad to be following Oli's direction to learn how to become a Divemaster, and I truly appreciated to see how well organized the dive shop was on every level.Finally, I also deeply appreciated to meet a very enthuastic staff, giving it all to provide students with a great atmosphere to study while creating wonderful memories !Thanks Crystal !

I did my 2 months of dive master program and it was a beautiful experience. Crystal Dive's training system is well-organized, and the employees here are friendly and helpful. I’m really thankful for my two mentors Oli and Sandy, who helped me to bring my diving skills to a new level. Highly recommend people to dive with Crystal🎶

My husband and I went through Crystal Dive to get our PADI Open Water certification course completed and had nothing short of an outstanding experience! The company itself is fantastic, but I truly think credit for our amazing experience is owed to our instructor Kelvin!!! Hands down, from the moment we met him, we felt like Kelvin became a fast friend instead of just an instructor. It’s very apparent his love for scuba diving goes deeper than any depth the ocean bottom can reach. Aside from that, you can see his passion extends to being able to introduce people to the beautiful world of scuba diving. He truly loves what he does and is a fantastic instructor because of it. Our first time in the ocean, my husband and I both had a little anxiety breathing underwater and being in that different environment. Having Kelvin with us made it so much more tolerable. He exudes comfort and tranquility underneath the surface, I felt more than safe with him. I never would have tried scuba diving if it weren’t for my husband pushing me to do it with him. This experience has hands down been a HUGE life memory that I will keep with me forever ❤️❤️ thank you Crystal Dive and a HUGE THANK YOU to our new lifelong friend, Kelvin!!!!! If you choose to come here, DO YOURSELF A FAVOR and see if you can request him!!! I guarantee you will not regret it!!! P.S., all video and photography footage is thanks to Kelvin 🙂

Embarking on the Advanced Open Water Diver course with Crystal, under the guidance of instructors Sandy and Ben, proved to be an exceptional journey. In just 2 days, I transformed from not having dived for years to feeling remarkably confident underwater. The expertise and encouragement provided by Sandy and Ben elevated my diving skills, making the experience truly unforgettable. A heartfelt thank you to Crystal for maintaining exceptional standards. Additionally, I completed my Enriched Air Diver course (Nitrox) with Faz, who was incredibly patient and helpful, adding another layer to my diving expertise. Special appreciation to Sandy and Ben for the invaluable guidance. Kudos to Crystal for consistently delivering remarkable experiences!

I recently completed my Divemaster course at Crystal Dive with Oli as my mentor, and I couldn't be happier with the experience. Oli's professionalism, expertise, and patience made the entire process smooth and enjoyable. Everything was there to give me the confidence I needed to become a competent Divemaster. The facilities at Crystal Dive were top-notch, and the support from the staff was exceptional. I highly recommend both Crystal Dive and Oli for anyone looking to pursue their Divemaster certification.This experience will forever be in my heart because beyond the quality of the diving center, I found a new family of divers. Oli regularly offered us activities to strengthen ties between the candidates: movie night, mini-golf without forgetting our snorkel test!Huge thanks to everyone who made my experience there so memorable : instructors, divemasters, my fellow divemaster candidates, customers, staff.

Completed our Open water with Crystal and it was great! Shoutout to big Rich and Mayo for being the best instructors. They were really good at bringing us through all the skills and were a great laugh!By the end of your last dive we were really confident with everything. Would highly recommend Crystal to do your open water course with.Also completed my advanced open water after my beginner one. Would definitely recommend doing it after your beginner course if you are unsure about doing it. Tom, our instructor was great and pushed us on the advanced!

I came to Koh Tao to visit the island and explore Scuba diving! I was hesitant on choosing a Scuba Diving school but so happy I went with Crystal.. Location is great and courses very professional. Did the Open Water with Mathijs and he is a great teacher. Happy to have been in a small group of 4 providing lots of support. I loved it soo much I stayed for extra 2 days to do the advance course. Luke was my teacher in a group of 2. Again a very positive experience with very interesting dives. Lots of fun in a professional setting! Thanks to Crystal team!!!

Great, professional dive school! Safe diving is a main concern at Crystal's, which is much appreciated. I went to do fun dives and ended up doing my Advanced Open Water Course. I was lucky to have Luke as my instructor who is experienced and very friendly. Everyone was very welcoming and the discount on the accommodation is a nice bonus! Highly recommend!

I completed my PADI Advanced Training in the past days at the Crystal Dive diving school, and my experience was simply fantastic! My diving instructor Ta was not only extremely experienced but also incredibly kind and funny. His professionalism and humor made diving an unforgettable experience. Crystal Dive in Koh Tao is definitely the best choice for all diving enthusiasts!Thank you to Ta and the entire team at Crystal Dive for an exceptional experience!

Absolutely amazing experience completing my Open Water with Crystal, everyone on site is super friendly, but I couldn’t recommend instructors Vik and Mayo more!! Vik’s experience and teaching style is simply next level, he is so knowledgeable and relaxed, it made me feel completely at ease. Mayo is an awesome instructor, super patient and attentive, he really boosted my confidence and supported me one on one until I got each skill. We were also lucky to have Nicholas assisting, I couldn’t believe how much support we had for a small group. I would love to come back to Crystal to do my Advanced, it was great fun and I definitely recommend! Thanks again guys 🙂

We were recommended Crystal and will definitely be recommending it to others! I did my open water, advanced and nitrox with them. Khosro and George were fantastic instructors and made it lots of fun. We've since dived with other companies and none of them were as good as Crystal!Just a little tip though - the accommodation on offer is very basic so I would advise upgrading if possible.

Wow! What an amazing experience! I did my PADI open water certification and did the pre-work and final exam online as to save time when I arrived at Koh Tao. My instructor Mathijs was fantastic. He was very professional and extremely encouraging. He was paired with Sandra, who is getting her PADI Masters and they are a dream team! If you can request, I would highly recommend! Not only did they make the diving experience fun but you also felt very safe the whole time. Crystal Dive does a lot of classes in smaller groups which is nice for learning. 10/10 experience and I can't wait to get my Advance Open water with them too!
03:21 19 Feb 24
Well where do I honestly begin! The whole experience with Crystal was fantastic from start to finish. My partner and I booked ourselves onto the Open Water Dive course with Crystal and I’m honestly so glad we did. We had Alex and Jake as our instructors and they were utterly fantastic…great blokes and from the very beginning we felt like we were in safe, competent hands 👌I loved the Open Water course so much that I immediately enrolled onto the Advanced and within 5 days I went from knowing nothing about diving to feeling extremely confident in the water and at depth. For the advanced course, our instructors Alex, Jake and Annie took my diving to the next level, offering great coaching throughout. Also another great benefit is that we had free accommodation throughout the course which was great! Thank you Alex, Jake and Annie for the great memories and the new friendships that we’ll cherish 👍 Great work Crystal, keep up the good work!

Crystal Dive team are all legends. My brother and I did our Advanced Open Water Cert here and we had an incredible experience. Alex our instructor was very professional and well spoken. He made us feel safe and informed and continuously tried to form positive relationships with us both onboard and under water. We did a few fun dives after and had Austen as our leader, also a legend, great diver and overall great guy! Thanks Crystal, we will be back! 🤿 🐋

In the summer of 22 I spent a week in Crystal doing my Wreck and Enriched Air specs and fun diving. Beside falling in love with the Island, I was amazed by how professional and passionate about diving and nature they were. I knew back then I needed to go back with more time. So I planned everything and went back after one year to do my Dive Master program.This time I spent a bit more than a month (did all e-learnings before) and 60 OW dives +/-.I absolutely felt at home!!!Everyone helped me in everything I needed (dive and no dive related). I had the time of my life and since then, I can say I have a family to whom I will get back many times in the future.The standards are high. They not joke around safety and they are environmental conscious.They have the best local food and sight tips. All equipment organized and a friendly and multicultural staff.They have tons of teaching and diving experience and they will be there, working with you till you make it! And their shop is walking distance to the big pier and to their fantastic big boats.(The island is full of dive centers where you need to walk big distances with your bag and do van transfers to the small boats that then take you to a bigger boat).I can't recomend enough!!!Thank you,Tiago.

We had a great time at Crystal when we did the open water and advanced OW PADI courses. The atmosphere is great, accommodation options are good, all the instructors that we had were very kind, patient and knowledgeable. They really make sure you understand the material and feel confident during every dive and in the end we felt at ease with diving. Big thank you to all the instructors that we had, especially Tom.

I felt safe and in good hands at all moments, and am so happy to have the necessary skillset to dive in different places now.Also a great deal with the included/discounted accomodations!

It was so much fun, they were patient when I was sometimes struggling but also kept pushing and helped me feel safe. It was a really great experience. We also did fun dives with Austin and Melissa and they were amazing as well! Thank you for the great time guys!

I had the best experience possible learning how to dive for the first time. I went to Crystal Dive to get my Padi Open Water, but ended up getting the Advanced as well. Big big thanks to the amazing instructors Bo and Abi for teaching me the diving skills. Very professional, but always in a fun way with laughter. I would highly recommend going to Crystal Dive because of the perfect location, the friendly people, cheap accommodation and good care from the staff. After I finished my courses I also did a fun dive with dive master Austin and loved every second of it. Thank you all and hopefully until next time!!

Had a really great experience at crystal dive school! As someone that's not the strongest swimmer, my open water instructor George patiently taught me the necessary skills so that I felt confident when we began diving in the ocean. My advanced diving instructor Cat was similarly attentive and made me feel confident diving at greater depths. Overall I'd highly recommend crystal dive school and I'm excited to bring the skills I've learned here to different dive sites around the world

We had an amazing day doing two entry level dives together with my 10 year-old son. Many thanks to our instructor - Vera, who was very thorough in her explanations and pool exercises. She gave my son full confidence when going into the sea.The two dives we had were very vivid and we spotted wide variety of corals, tropical fish and marine life. All the time Vera was next to us taking care for our safety and overall experience, also showing us what not to miss seeing under the water and later on the boat debriefing and checking the types and names of all the exotic species we saw.Overall, we had a fantastic day in the water with a very professional and dedicated team.

We were fortunate to be assigned Tom Schluter as our Open Water instructor. Though sometimes strict, his coaching and practice were very thorough. The training and diving exceeded our expectations, and we felt very safe and comfortable on the dives. My girlfriend, who is not an avid swimmer and is somewhat afraid of the ocean, did surprisingly well thanks to his training.

Crystal Dive is amazing. Highly recommend it to anyone looking at diving in Koh Tao. I attended Crystal and completed my open water and advanced diving. I had Luke and Melanie as my instructors who were professional, punctual, knowledgeable and fun. This has allowed me to become a safe and competent diver which has given me the confidence to dive elsewhere. I also dove with soon-to-be dive masters Benjamin, Marco and Tobi throughout the course who were also supportive and helped me to better my skills. I hope to be back diving in Koh Tao with Crystal soon!

Crystal was recommended to me time and time again, and it surpassed expectations! Other than the beautiful beachfront location and the super friendly and accommodating staff, my open water experience was everything I could’ve asked for! I had Tom as an instructor and he was incredible. I haven’t had learning be that fun and enjoyable in a long time. Constantly learning and having a blast, and always felt safe in such unknown conditions. Would highly recommend and I’ll definitely be back!

First of all, I just want to say that Crystal Dive is a fantastic dive centre. The staff are professional, welcoming and friendly, and always happy to help.I spent around 10 weeks with Crystal, as a marine conservation intern with Coral Tribe and also doing lots of fun diving with Crystal. My internship included Eco Reef Check, Marine Resource Management and also the PADI Whale Shark speciality. The Eco Reef Check and Marine Resource courses were challenging, both physically and mentally, but I passed them with the support of both Jenny and Simon. The internship was very educational and it really helped with my fish ID and surveying skills.I also took the (scary) Self-Reliant course with Simon, again, another challenging course but thanks to Simon's considerable patience and understanding (which a lot was needed), I passed the course. Being a self-reliant diver is definitely a really good certification to have - it opens up a whole new world and definitely makes you more conscious of preparation, planning and safety.I also have to mention Tim, who introduced me to the wonder that is UV diving. If you love Avatar, then do try UV diving - you will be amazed. I am really grateful to Tim to have had this opportunity.All of the staff at Crystal are lovely and you certainly are made to feel part of the Coral Tribe/Crystal family from the start.I would definitely recommend Crystal Dive as part of your diving adventure.

Absolutely couldn’t have had a better experience at Crystal!!! The team is so beautiful and welcoming creating such a family like atmosphere. All the instructors are so warm and really put in true effort to make u feel comfortable, safe and of course have a good time! But most of all a massive shout out to my instructor George!! Hes an absolutely wicked guy who made me feel so safe and comfortable while learning as well as while dealing with some rough dive conditions. I was extremely lucky to have him not only during my open water course, but also advanced course and wreck speciality. His ability to place confidence and trust within us as we learnt really made a huge impact. It was a really big reason as to why I did additional courses, when I only had planned to do the open water. The other half of the reasoning behind this is purely how much I loved they way crystal (and of course George) approach teaching. They perfectly mix professional, proper diving with a really lively fun atmosphere. One massive part of crystals teaching is that of personal awareness regarding your environmental impact while diving. They seriously care about marine conservation and care, that being clear both in their teaching but also their close involvement with the Coral Tribe (a marine conservation organisation), which is a really important aspect of choosing a dive school. It’s been such a adventure, seeing a glimpse into a whole different world, and I’m really thankful that i was able to discover a new passion through crystal!

Had my padi ow accomplished with Luke. To me, he’s so reliable in every circumstance I was facing whether in a pool or under the sea I feel so thankful for that and for instructing me to discover another essential skill for life 🩵

I came here to do my instructor course and was really impressed by how thorough and professional they are. I had Bob and Oli as course director for our course, they really spend their time with us to make sure that we really get everything right and up to the standard. I am now working full time as a diving instructor, thanks to them. This is one of the highest standard dive shop that you can get in Koh Tao. If you’re looking for a dive centre to do your IDC or any pro level, i’d say just go for Crystal.

I did my IDC here at crystal and I've learnt more than I could ever imagine. Friendly and helpful staff here. Every facility is in-house so it even feels like a college of diving. Now I'm successfully and happily working in the diving industry. Special thanks to Oli and Bob who oversee the pro level courses here. If you ever thought of doing a Divemaster or instructor training I cannot recommend Crystal Dive enough. Get your training here!

I completed my Dive Master here. I chose Crystal Dive initially just to do my open water course. But I fell in love with diving here. What made me stay was the facilities, training standards and atmosphere of the Dive shop.During my dive master I was trained to the highest standard which has now got me a job in the dive industry.Couldn’t recommend this place anymore to do professional level training!

Me and my partner completed our open water diving and two adventure dives. And we absolutely loved it, our instructor Attila was incredible, amazing communication, great at keeping us comfortable and safe while diving and a real expert at what he does.Everything was done professionally from the minute we walked in.We definitely would recommend, all the instructors seemed lovely. And a big thanks to Bo for getting us booked in and sorting everything out for us!Hope to come back one day 🙂

Just finished my Open Water with Crystal, what a beautiful adventure! I can now definitely recommend this school. We had plenty of time to practice our skills in the pool before moving in open water, which really boosted our confidence on the first dives.Our instructor Sandy was professional, calm and so knowledgeable, he would tell me whatever I needed to do to improve my skills after the dives. We were feeling really confident when diving with him, he was brilliant!I stayed on the resort in a double-bed private room (which was cheaper than staying in a bunk bed in a hostel!)Overall fantastic time here, thanks Crystal, see you soon!

Had the best days on Koh Tao with this dive center! I took my Open Water here and can only recommend it. All the employees are nice and you felt really safe. My instructor George was the best. Patient, professional and fun. We lived cheaply at the diving school, so it was very easy. Both diving and hotel at a super price!!

We did the PADI Discover Scuba Dive course and it was an incredible experience, highly recommended. We had Sandy as an instructor and he was very professional and friendly, we had such an amazing experience underwater and saw a lot of coral, tropical fishes and even a turtle. We also choose the professional photos extra option and they turn out amazing (see photos). Top diving school and experience! 💯

I completed my open water diving license here and was more than satisfied!Vera was my diving instructor and for me she was the best diving instructor I could ever imagine. It took away your fear and panic at all times, both above and below the water. She was calm, patient and explained and demonstrated everything in detail.I knew that if she was with me at a depth of 18 meters I would be safe and so I felt super safe!For me it was one of the best decisions I made and I can't wait for my next dive 🥰🤿

Crystal Dive in Koh Tao is an excellent school to start your diving adventure. The staff is chilled but very experienced, the classroom lessons are very informative and they have well equipped boats for the dives.Another great thing is that each instructor only teaches 3-4 students max so a lot of attention is given to each person.Our “sergeant major” instructor Mathijs was very knowledgeable about diving and made us feel safe from day one.I just completed my Open Water and now going on to do the Advanced!

My partner and I had the best experience with Crystal dive! Big shout-out to Luke, who had infinite patience and helped us to coordinate our dives (we were at different levels but managed to do all the dives together). George, then, our diving instructor, was absolutely amazing, he helped me gain more confidence and improve my skills underwater massively (I arrived as an open water and am now an adventure diver). I would definitely recommend him as an instructor, he's the best teacher!

I came here to finish my advance course and it was an amazing experience. George took my partner and I under his wing and was a great teacher, always ready to help and show us how to improve. He is also a great guy in general. We had 5 incredible dives some more challenging some easier but always had fun and saw beautiful marine life. 100% would come back!

My experience with Crystal was absolutely amazing! I started here with my Open water, but ended up doing my advanced and rescue course aswel, because I enjoyed it so much. The classes were very clear and we really took our time to make sure everyone was comfortable with all the skills, before continuing. And of course a very big thank you to all the amazing staff members who are incredibly nice and patient; with an extra special thanks to George! I wouldn’t want to have done my courses anywhere else, thank you all much!

Just finished my PADI open water course with Sandy!Wow! So incredible. Super chilled and superb tuition from our instructor Sandy.I’ve never been one for swimming in the sea. And struggled with buoyancy excercises previously (I was afraid knowing that this would be a requirement for the course)Sandy helped put me at ease and guided me how best to do this exercise. It took some goes but he could see my progression and knew I could do it with the right guidance (glad to say I eventually did)As we progressed through the skills I was amazed at how quickly everything came together. Sandy really was a wizard in just being able to add the right amount of instruction, not over complicating anything and allowing for an easy learning environment. He really cares and also captured some amazing video footage of our learning progress and the training dives! Capturing amazing memories I will never forget!Would highly recommend Crystal Diving School to anyone! It was a stress free experience from initial enquiry, to accommodation right through to qualification.Very tempted to go for my advanced open water qualification. No prizes for guessing which school I will go back to 🙏🏻

WOW.Brilliant centre and facilities (training pools, classrooms and discounted rooms).Myself and 3 friends booked onto the open water course, our first scuba experience. All instructors were fantastic, thorough but patient and good fun always.Particular shoutout to Mathijis, our main instructor/ dive guide, who made it all the more enjoyable and really went above and beyond to ensure I could pass after I had food poisoning and had to miss a day!

I did my Nitrox course and few fun dives. The 1st impression was really good. Na who checked me in was friendly and helpful. She is a Scuba diving instructor too. Luke was my instructor, he was knowledgeable and super supportive during my course and dives. I came across dive masters in training.. must appreciate Charlotte and Aubree for doing a great job and sincerely wish you both all the best.The stay with the dive center was ok.. it is overall cheapest in the area especially if you are doing a course or activity with Crystal. Crystal dive center is very well located, very close to pier. Literally 2 mins walking distance.

Taking the Open Water at Crystal Dive was the best experience! Every step of the way George made all of us feel very comfortable and I really enjoyed learning all the skills. We were a team of three students (max amount is 4) and we had a lot of fun. Crystal is also a social place and there is a bar where you can grab a beer and just hang out.Would 100% recommend everyone to go here to take their certificates - and to ask for George to teach you everything you need.

Look no further! Crystal Dive Koh Tao is an amazing diving center. With so many options and possibilities to chose from, it can be overwhelming to find a reliable and trustworthy company. I have only positive remarks about my experiences. The admin team is quick to respond, organized, accommodating and very friendly. I did my adventure diver course with Kelvin. He is an amazing teacher! His professionalism, guidance, and patience helped me increase my confidence as a diver. He really took the time with each of us without rushing and at the same time challenging us with activities underwater. The dive logistics and safety protocols were very well executed.My daughters did the mermaid discovery class with Meng Xing. She was great, encouraging and super patience. They wanted to stay longer after the course ended even though they were quite cold in the water.My eldest did the bubble maker course with Mathijs. I could see right away that he is passionate about teaching kids. His warm personality helped my daughter feel at ease and was soon joking in the pauses with him. Mathijs introduced scuba diving in a very simple and clear way with fun games and adaptations to respect the child’s readiness to take it to the next level. My daughter is now hooked and once she has the age, would love to come back and do the PADI Junior with him.

I spent 7 weeks at Crystal Dive completing the AOW- Divemaster Lifestyle Internship and it was honestly the best 7 weeks of my life!Crystal is an amazing dive school. Everyone is super helpful and friendly, from Bob greeting me on arrival and carrying my luggage to my room they had arranged, to the office staff (Luke and Naa in particular) helping me out with any question or need I had at any time.My advanced open water course was great- my instructor Luke was professional, lovely and funny, and every dive was amazing. I then completed my rescue course with Mathijs and Olivia, and whilst intense it was such a fun few days! Mathijs and Olivia were very thorough with everything, and I came out of the course feeling very confident and well equipped to rescue someone in a real life situation.I then had a period where I built up my dives (the free unlimited diving was so good for this) and got to know the dive sites and the people around the dive school. The way the school is run with the consistent morning and afternoon dives works well and it makes it really easy to fun dive at many different spots.For completing my divemaster I picked Mathijs as my mentor. I couldn't have asked for anyone better; he went above and beyond to make sure I completed everything to the best of my ability, and taught me things that he didn't have to but that have helped me so much as a diver. He was there for me the whole time both professionally and personally and I'm very grateful to him for this. Oli, one of the course directors, was also very helpful and was great with helping organise my schedule to make sure I fitted everything in on time. He was also there for all of the divemaster candidates if we had any issues, diving-related or not.Overall, I couldn't recommend Crystal Dive enough! I had the best time diving and made so many good friends. I can't wait to hopefully return soon and do my instructor course here:)

My girlfriend and I completed our PADI open water at Crystal Dive in 4 days. We were lucky to have the amazing George Cupa as private instructor. Learned a lot in these 4 days thanks to the always clear instructions from George, who taught in an enthusiastic way, which made diving extra fun. A big advantage of Crystal Dive is the location next to the pier and the diving school has two swimming pools. Can only be recommended!

A wonderful diving school. I was supposed to spend only a few days there to complete the Open Water course, but I ended up extending my stay to do the Advanced course. The equipment and organization are top-notch. My instructor, Khosro, showed infinite kindness and great patience. I was able to share my fears with him, and he welcomed my emotions while reassuring me. I can only recommend this school! Thank you for everything!

I had a great time getting the PADI open water cert at crystal dive! Giancarlo Fazzi (Faz) was my diving instructor and he was patient, calm, and extremely capable throughout the course. I went with the e-learning option because my time on Koh Tao was limited, but my course mates who did the classroom option seemed to get through the material faster. I stayed in Crystal Dive’s discounted accommodation, which was pretty bare bones, but there was AC and I was able to get any amenities I needed at nearby groceries and pharmacies. We caught the end of monsoon season in December, which meant we had low visibility under water, but we still saw lots of fish and coral. I feel confident in my ability to dive in open water and look forward to doing fun dives and advanced certs in the future!

I did my Open Water and Advanced Open Water Diver during my vacation on Koh Tao. It was the best decision and I hope to come back here to take more courses and specialize further. I had Olli as a coach and I couldn't have asked for anyone better. Always friendly and competent, but also a good teacher with a clear structure to impart important knowledge that is essential for returning safely from every dive. We had Sam with us as support, who was on his way to his divemaster. For me a perfect team and an unforgettable time. Many thanks to both of them! Good Stuff Gentleman and never forget: Chillin!

Took mum out for a discovery scuba dive experience. Though I have my ow licence, mum had very limited experience with diving.The whole day experience covers a morning pool session and went out with the boat for two dives in the afternoon.We had Alex on the day.. Alex is really patient with my mum and very encouraging. After the morning session, mum was super confident and excited for the dive. Though the first dive attempt was a bit rough for mum that she got a bit panicked but Alex was really nice to her to calm her down. And with his encouragement mum gave the dive another go. And really enjoyed the diving experience.Highly recommend Alex. 🙂 thank you.Will definitely coming back to do my adventures dive with you. 😊

I've spent three weeks on Koh Tao and did an internship with The Coral Tribe. As this is a review for Crystal, I will try to start focusing on them from now on. Due to my time around Crystal, I've formed a positive impression and want to share my experience. The dives I made onboard the dive boat Crystal 3 have been well executed by Crystal Dive Koh Tao. The boat crew is very helpful and contributed a lot to the overall great experience. The provided equipment is in good condition and of good quality. They can arrange an accomodation for you at the Koh Tao Regel Resort.I did my Padi Rescue Diver, EFR, Wreck, Deep, and Search and Recovery specs. Despite being with The Coral Tribe during the week, they accommodated all my wishes in my schedule, maximizing my experience.My instructor was Kelvin throughout all of them.We spent some great days, had great dives and I was able to learn a lot.We started with the EFR course. I was the only person during this course, so Kelvin was able to focus on me at any point. The teaching rooms are well-equipped, and all of them have air conditioning, which made it really convenient because it was very warm with high humidity.My second course has been the Rescue Diver. I did the E-Learning Version of the Rescue Diver offered by Crystal Dive. This allows you to do the theory part at any time. After completing the final exam, the course started with a knowledge review which helped to refresh the theory. Before we got into the ocean, we had some time to do all of the skills in a pool session. The pool has been large, clean, and even had sun protection if needed. Even though I was really excited during the practical Exam of the Rescue Diver, my "hell dive" at the end of the Rescue Diver was probably one of the best dives I've ever had. Thanks to Esmee and Bella, two DMCs who joined us during the Rescue course. We have been two people doing the Rescue Diver course, Kelvin, and the two DMCs. All of them have been very professional, and I am glad I was able to do the course with you guys!On the following weekend, Kelvin and the guys at Crystal Dive Koh Tao have been able to fit my requests for three more specs into my tight schedule.The Deep Spec started with a trip to the famous dive site Chumphon, which would end up as one of my favorite dive sites of all time. I asked for Nitrox for the following dives because these will be some quite busy diving days. Kelvin arranged that for me. The charged price is very fair. After checking your tanks, they will be brought onto the boat which was very easy.For the Wreck Spec, we visited the HTMS Sattakut, one of a few wrecks around Koh Tao and also another newer wreck (No Name 313). On the first dives, we explored the wrecks from outside and afterwards we sat down and made our plan for the last dive. On the final dive, I was ready to penetrate the wreck which led to an unforgettable experience.The Search and Recovery Spec was very interesting and a lot of fun. Using different search patterns and learning to use a liftbag are very handy skills which you could use in many situations. I was even able to use them on my internship with The Coral Tribe.In total, I did more than 40 dives with Crystal Dive Koh Tao and The Coral Tribe. The staff has been kind, courteous, and they are just amazing people. The diving center is right next to the beach of Mae Haad and the pier. That means no long walks with heavy diving equipment. Thanks to all people involved during my stay. Thank you, Kelvin, for the great experience. I would also like to highlight that sustainability is very important to me, and the guys at Crystal Dive Koh Tao are very aware and caring about the environment.TL;DR: Amazing experience, great instructors, fair prices.

Booking the OWD-course at Crystal Dive was the best decision we made on our trip! It was an amazing experience that we will remember for the rest of our life.Special shoutout to our instructors Dani and Sandy. Sandy was an incredible teacher with a great attitude. Even though we struggled at times, he was always patient and sensible and guided us through it all. When I almost had a panic attack 5 meters under the sea, he helped me to remain calm and always believed in us that we could do it, even when we struggled. We are so thankful that he made this experience possible for us!We highly recommend booking your Open-Water-Diver course at Crystal Dive (and to request Sandy as your instructor, if possible).

I'm so glad my partner and I picked Crystal to complete our Open Water dive course. Our instructors Mathijs and Magnus were incredibly professional but made the experience so fun, too. It felt very safe learning skills in the pool first so that we felt completely confident in the sea.We loved it so much that we decided to complete our Advanced Open Water immediately afterwards, which was even more enjoyable and rewarding.Crystal run a tight ship; they have an excellent reputation, and all instructors are very passionate and knowledgeable about the sea, diving, and conservation. I highly recommend them to anyone looking to dive in Koh Tao.

My dive wife and I did our Open Water, Advanced and Nitrox at Crystal Dive. Out of all the dive schools on the island, Crystal had been highly recommended and so was our instructor Sandy.The staff and other students were super friendly and easy going. Sandy our instructor was professional and extremely reassuring both in and out of the water. The amount of calm he could exude at depth in complete silence should be bottled. He was also very intuitive and knew exactly how much to critique, when to push us to do more. This is of course balanced out by getting to do some of our course work by the beach, with tasty drinks in hand. 12/10 would highly recommend.The chilled out Crystal Dive vibes and getting to dive the absolutely phenomenal dive sites that Koh Tao has to offer has been absolutely life changing. I feel like I could have happily have forgotten I had a flight back home and just stayed there forever. Now back home I need to dive semi-regularly or risk getting dive withdrawals. I can't wait to have enough in my dive fund so I can come back and do more courses!

I just completed my OW course in Chinese with Instructor Castiel this week. The four-day course was super fun and Castiel was very professional and patient. He demonstrated everything in great details and really helpful in improving my scuba diving skills. The DM with us was very friendly and always cheered me up. Although the wether was not so good these days, the Koh Tao undersea was still splendid and the journey was with all good memories.I highly recommend Crystal Dive and my instructor Castiel to everyone who wants to receive the best diving training courses. Definitely will go back again for my future courses and fun dives.

Completed my Open Water course and 2 adventure dives with Carman this week. Couldn't have wished for a better experience and a better instructor; she was really patient, extremely informative and made it so much fun. It exceeded all my expectations, and I was taught about the marine life around Koh Tao, as well as developing my scuba diving skills. I've improved massively and that is all thanks to Carman's amazing teaching, who I can now call a friend as well as an instructor. I could not recommend Crystal Dive highly enough, and especially my instructor Carman. Easiest 5 stars I have ever given.

I recently visited Crystal Dive and had an incredible week of fun diving with their team. The professionalism and dedication displayed by the staff was truly impressive. The instructors were highly knowledgeable and ensured each dive was conducted seamlessly, instilling confidence and a strong sense of safety. Their mentoring skills and willingness to share knowledge greatly enhanced the diving experience.The instructors and dive masters were polite, professional, and provided valuable guidance throughout my time at Crystal Dive. The friendly atmosphere created by the staff at the dive shop added to the overall experience. I highly recommend Crystal Dive to fellow divers or anyone looking to get into diving. Their commitment to excellence and customer satisfaction sets them apart in the industry. I am immensely grateful for an unforgettable diving trip and look forward to returning in the future.Overall, Crystal Dive is a top-notch dive shop that offers an amazing and fun diving experience.
