I just wrapped up my Open Water certification at Crystal Dive in Koh Tao, and I had an incredible time. Greg, my instructor, was really fantastic – he explained everything so well and made the whole process really enjoyable. I'd definitely recommend them to anyone looking to get certified. The fact that they include accommodation during the course was a huge perk, too.

I just completed my rescue, dpv, sidemount, and deco specialties with Crystal. They are awesome — everyone, from the instructors to the DMs and boat crew, was nice, patient, and very professional. Oli and George are the best instructors ever! I had a blast the whole time. For me, diving with Crystal: it's as good as it gets!

I did both my Open Water course and then the Advanced Adventurer course with Vera - a big recommendation! Vera is very competent, structured and motivated in teaching knowledge & skills, which made me feel very safe in the water and enjoy my diving experience. I would do another course with her anytime! 🤿

I booked my open water - with accom inc - had my own private bungalow! Loved it!!! As I have been wanting to learn how to dive my whole life!! Finally got the chance to do it! The price was very reasonable! My dive instructor Anna was fantastic!!! She was so so so patience and reassuring! The best 🙂 and I been recommending this place to everyone I met. This was actually recommended to me by a friend also! I will definitely stay and dive with them next time I’m in koh Tao! The centre is also @ a very good location next to the port! Surrounded by loads of restaurants etc.one thing thought the bungalows does now have hot water!!!! But it’s okay as it hasn’t been cold at all!Sunset view is lovelyThe in house restaurant- reasonable prices

Here I was able to finish my diving training and then do several dives.I felt safe and comfortable at all times.Previously I had only booked three nights here. In the end it ended up being a full week.In addition to the discount on overnight stays when diving with Crystal, the location of the accommodation is also very attractive.The room itself is basic, but was completely sufficient for us. The bathroom was also fine and basic. Everything was clean and the bed was comfortable for us. Not too hard and not too soft either.The only thing is: There is no separate shower here and there is little hanging and storage space. But that didn't bother us.If we go to Koh Tao again, we will try to stay with Crystal again and dive with the great team.Thanks for the nice time.

Instructor : Benjamin ( UK guy )How was it : the best instructor I have met , I have tried instructor from China , pattaya and Kohtao island , the most in detailed and caring one is Benjamin from crystal dive Kohtao . On top of this the price is totally ok compared with pattaya one or in China .

After looking at many options to complete an open water diver program at Koh Tao, we chose Crystal Dive and we couldn’t be happier with our choice. Our instructor Kelvin was great from day 1, he made us feel comfortable and very safe and he was very patient when explaining the fundamentals of diving. Would definitely recommend to go for it, we requested accommodation as well and the rooms were great right by the beach and next to the dive center. Thank you Crystal Dive and Kelvin for our making our first diving experience unforgettable!
