We did your PADI Discover Scuba from Crystal. Special thanks to Kelvin, our instructor, for being so enthusiastic, supportive and a great trainer. Crystal is super professional and they take great care of their students. An amazing diving experience!

Did my open water + advanced scuba courses at crystal dive center, koh tao. It was a great experience. Special shout out to Cat and Harris, our dive instructors, who were really patient and motivating throughout the course. Had some great dives, including a night and a wreck dive as part of the advanced course. The stays are right next to the beach. Overall, really great experience. Would totally recommend.

Had an amazing experience at Crystal Drive finishing my open water. I had the instructor Alex, who was amazing and went above and beyond the expectations. After having difficulties equalizing, he came in on an extra day so that I can complete the course. Would highly recommend.

Had Ben as an instructor and would recommend him to anyone. Very experienced and had a laugh throughout. If anyone is looking to dive Crystal is the place to go and definitely ask for Ben!

I did my Open Water and Advanced with Ana and Evandro, specifically Evandro teaching me. They are both fantastic instructors, and couldn't have had a better time. They are great teachers, with Evandro clearly explaining and demonstrating all the skills and techniques. I never felt worried as I knew they were always there to guide me. Thanks for everything and I can't wait to be back!

I recently did my Open Water and Advanced Open Water certification at Crystal Dive and the experience was great. The staff members there were always friendly and my instructor Vic was incredible, as he is both very knowledgeable and wholesome. The dive locations were also great. Also, when considering the prices for the courses, this is arguably one of the best places on Earth to get a diving certification. Overall, I strongly recommend Crystal for any new or experienced divers.

Couldn’t have chosen a better place to get my open water in Koh Tao, Sandie and Aex were incredible instructors, being able to stay in a private place made the process a lot better, also being able to train in a pool before going into the ocean, 4 days training instead of 2 like other schools, you really learn properly

I did a discovery dive here and I absolutely loved it. I was supervised by Alex, he made sure I knew what to expect from each dive, checked on me throughout the dives and helped me stay calm. I even got to meet a local legend (Steve the Pufferfish). I like that you can also convert from a discovery dive to the open water course, which I would've done if my schedule allowed. But next time I'm in Koh Tao, I'm definitely coming back to Crystal Dive 😁
