Only had a very short stay in Ko Tao, but I was still able to complete the deep, wreck and nitrox courses. In addition, my diving skills were amazingly improved by the competent diving instructors. The prices for the courses and accommodation are surprisingly affordable for the high quality, and great emphasis is placed on safety. Thanks again to Sandy and Hugo for this great adventure!!!

I did my padi at Crystal Dive with Tom and Cat, I started off extremely nervous and by the end I was confident and loving being under water. You have plenty of time to get to grips with the breathing techniques in the pool and then head out to sea after a couple days which I thought was perfect and not rushed at all. Me and my friends took a while to get use to some of the tasks we had to do and both instructors were so patient with us and was always making sure we felt comfortable and safe under water. We have been travelling for 6 months and this was one for the most incredible experiences we have ever done I can’t thank Cat and Tom enough. We’re now looking to do our advanced in the Philippines

I spent 5 weeks with Crystal to become a Dive Master and I loved everything about the experience.The entire staff is welcoming and friendly, and we had a big group of dive master candidates at the same time, which made it easy to socialise. They also organised extra activities for us to get to know each other better, such as cinema, mini golf or a special dive trip just for their dive master candidates.The dive school is well organised and very professional, making it easy to achieve everything for your Dive Master. But on top of that Crystal is doing more than that for their program, giving you lots of opportunities to learn more, assist more and get additional specialities done, that are a great addition to the program.All of that gave me the opportunity to learn from different instructors, which helped me a lot to become a better diver! While really all staff are supporting you whenever you need, I want to say special thanks to the ones that I worked with directly: Oli, Bob, Abi, Sandy, Mathijs, Mel, and George! I learned a lot from you all, and I really appreciate the time and effort you are putting into a great dive master program.I highly recommend Crystal Dive for the dive master program. My 5 weeks there were just an amazing experience, and i am already looking forward to returning one day!

Wow, what a fantastic experience! 🤩I spontaneously decided to do an open water course and am very happy that I chose Crystal. Quick and detailed information in advance via email, careful handling of health issues and free accommodation during the course.Eternal thanks to my instructor Kelvin, who introduced us to the world of diving so carefully and patiently. I’ve always felt very safe and couldn't imagined a better teacher. 🙏The dives in the ocean in such great spots were soo amazing! How lucky to have experienced something like that!Big thanks to you all! ❤️

Fantastic value as course included free accommodation on site for me and my two friends. Massive shout out to our instructor Big Rich who’s tell it to you straight attitude mixed with some good crack made me feel both confident and relaxed throughout all the training and the all the dives. Couldn’t recommend a better dive centre!

Just Completed my owd with crystal, and what an experience it was. My instructors Tom, Vera, and Trevor were a pleasure from start to finish. We were in a small group of 3, so all there knowledge was all focused on us. From the pool training, too the 4 sea dives off the boat, they took every step to Make us feel safe, but also enjoy the training of becoming certified divers.Can’t wait to come back soon and do my advanced!.

Had the best time doing our open water with Big Rich! I was super scared of the mask removal skills and he was so accommodating and reassuring which made it much less stressful. Couldn’t recommend this dive school and Big Rich anymore ☺️

I did my Open Water divers at Crystal and had such a great time. My instructor George took really good care of me and made sure that I was always feeling safe and comfortable underwater. I enjoyed diving with Crystal so much, so that I spontaneously decided to do my open water advanced course.Thank you Crystal Koh Tao and thank you George for showing me the underwater world. I will never forget this adventure 🙂

My partner and I did the open water dive course and our instructors, Kelvin and Eloide, were so wonderful! They were patient and helpful throughout the entire process. The dive spots were unique and we saw many different species of aquatic life. We even got to identify them post-dive! Honestly, I was a bit nervous to dive for the first time, but all the learning and reinforcement in the pool made it so much easier in the ocean.We received accommodation with the diving course, which was nice! Rooms were tidy and A/C is good.I would recommend this experience to anyone that goes to Koh Tao 🙂

I did my OWD with Alex and Rachel and had a great time! The learning groups are super small and the diving instructors take each one into account individually. The four dives were in great spots and beautiful. Thanks!

We did our OWD at Crystal and it was great! Alex and Rachel explained and taught us everything in a wonderfully understandable and detailed manner, took all questions seriously and answered them, and made the course an all-round great experience for us! Thank you very much and maybe see you soon!
Great experience! George is an amazing instructor.
