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 😁

I did my advanced open water qualification with Alex and it was amazing! He was a great instructor, giving clear directions and making sure we were comfortable with all our diving scenarios, it really helped me to make the most of my dives with Crystal dive. The dive school is very professional and well run, with discounted accommodation during the course too! I was even lucky enough to visit Sail Rock on my second day of the course which was my favourite dive so far! Would strongly recommend to anyone wanting to dive in Koh Tao!

Did my Open water certification. The instructor, Ben, was amazing! He made everyone feel safe and properly taught us the fundamentals of diving. 100% recommend him as your instructor.The price for the open water was slightly more expensive than other places but they had a pool which was great for learning on the first day.Rated 4 stars because they told us that we would get free accomodation for open water (4 days) and advanced (2 days) but when we were about to book the advanced certification, they pulled out a 300 baht per night room fee. Apparently we had to pay for both open water and advanced at the same time to get all 6 nights free but that was not what we were told when we initially booked. Even though we mentioned the original agreement for the accommodations to the receptionist, he did not care and had a "it is what it is" attitude.All in all, great place for new divers to get the open water certification, but there are cheaper places on the island to get more certifications (advanced, specialties...)

I recently had the pleasure of diving with crystal dive Koh Tao, and I can’t recommend them highly enough!The facilities are all top notch, with a comfortable and well-maintained equipment. Kelvin was highly experienced and incredibly passionate about diving. He took time to ensure that as a beginner I felt at ease.The dive sites themselves were also stunning! Each dive was also very well-organized and the guides provided excellent briefings, highlighting what we could expect to see on our dive.The atmosphere in general is extremely friendly and relaxed, which made it easy to meet fellow divers and make friends!Overall, Crystal Dive exceeded my expectations, whether you’re a seasoned diver or a newbie looking to get certified, this is the place to go. I can’t wait to return for more underwater adventures!
