I did my Advanced with George, who gave me the best diving experience. The dive sites are amazing and he does a really good job as an instructor! I would definitely recommend this experience to anyone who enjoys diving and is ready to step up their game to the next level.

The most seamless experience of getting certified. The Crystal Dive team took care of everything during my stay, it was a wonderful time. I registered initially for solely Open Water but felt so comfortable with them that I finished my Advanced Open Water too. If you visit Koh Tao, prepare to extend your stay because the diving experience is exemplary.

Amazing dive school. My instructor was Michaella, and she was the best instructor me and my buddy could have asked for. She ran us through everything we needed to know at a pace we felt comfortable at for my OP and advanced. 10/10 recommendation.

I’ve done the open water course with Kelvin as instructor and Trant as a dive master and it was great! really enjoyed this experience and very glad I chose Crystal as my diving school.Both Kelvin and Trant were so professional and kind, made me feel very comfortable and in good hands, and made these days both fun and interesting.The deal with the accommodation was the best deal we saw on the island and the resort is also nice and good for staying there.Highly recommend on Kelvin if you have an option to choose your instructor, he’s really great!

What an experience! After researching what felt like thousands of dive shops in Koh Toa we selected Crystal. Crystal stood out above the rest and we automatically got a great feel for the place as soon as we stepped foot inside. As I was nervous we booked a discovery scuba day to try out scuba. Cat our instructor was super professional, thorough and passionate about scuba and the ocean. We went to the pool to learn the basics and headed out on the dive in the afternoon. I was really nervous but Cat was incrediblely reassuring. Being around her made me feel safe and calm. We loved the discovery so much we booked onto our Padi open water, requesting Cat. As well as booking the onsite accommodation which was right on the beach.We had one day academics, one day in the pool and 2 days diving. Cat was super knowledgeable, passionate and a joy to be around. We are even planning to return to Crystal later in our trip to do our Advanced, with Cat of course! A huge thank you to Cat for making the experience so incredibly powerful, memorable, and for introducing us to the magic of scuba.

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.
