Where do I even start? If I could leave 11/10 I would. Michaella and Luke have forever made me a diver and introduced me to my new love underwater. So… Crystal dive, I thank you. For anyone curious why here? Let me tell you. One, it’s obvious the pricing is competitive and cheaper than anywhere back in the United States. Two, you get your housing included with the price. Free room… say less. Third and the most important, THE INSTRUCTORS. Not only are Michaella and Luke extremely knowledgeable about diving, but they make learning so fun, safe, and exciting. Everyone goes in with anxieties, but by the time you’re in the water, everything will be okay. I am the type of person who asks a lot of questions and they were there every step of the way to answer them whether it was before, during or after class. Crystal Dive brings you into a classroom environment, then the pool and lastly out into the ocean to learn. Everything is closely located as well. I could grab breakfast, a snack, walk to class and the ocean all within 3-5 minutes or less everyday. Seriously it’s that close. The equipment is all very up to date, the boat is safe to charter and the other divers at different levels are all there to help and support you on along the way. It truly felt like a family and big diving community. I can truly say that I trust Michaella with my life. I am a floater and she literally helped me from floating away in the ocean. It takes a special person with talent to help someone with no words using just hand signs 10m under water. I am already planning my next trip back for the advanced course and I hope that Michaella, Luke and Jeff are all there when I arrive. Thank you all!

great diving school with a great instructor.We completed our Open Water Dive course (4 days) at Crystal Dive Koh Tao and were very excited! Above all, our instructor Vera made this course super special for us! We felt super safe at all times and had fun and joy both above and under the water! Thanks again to Vera! Would come back at any time!Accommodation can also be booked in combination with the diving course - TOP price! 🙂

Never planned on doing scuba diving but a friend really recommended Crystal Dive as a one time chance to get my PADI Open Water certification. My instructor (Melanie) was really patient, since I had many fears to overcome under the water.Also the accommodation right kn the beach in a bungalow was great!Can recommend 10/10

We came here to do our rescue diver certification. It was great, we learned so much and still it was fun. We even stayed longer to also do our wreck and deep spec.Special thanks to George for teaching us and keeping us save all the time! Also thank you Michaella for doing the EFR training with us. And finally thanks to Evan for assisting and surviving 🙂 our rescue diver exercises and the scenarios.The whole team is well organised and super friendly. Definitely a place to recommend!

I loved the Open Water course with Crystal so much that I immediately enrolled in the advanced course. For the advanced course, my instructor, Melanie, took my diving to the next level!She was always there for me, making sure I felt safe and confident. Melanie is not only an amazing dive master but also a genuinely kind person. Many thanks to the Crystal team and especially to Melanie! This adventure will always hold a special place in my heart.
