We have taken the PADI open water diver course and it is truly great. The monitors are super nice and very patient until we learn everything.We received 2 theoretical classes, a practical class in the pool and a written exam. Everything is very easy and the information is easy to digest.They gave us all the material that was very well preserved and in our exact size.Finally we did 4 dives. The instructors gave us a great feeling of security and took good care of us. At no time have we felt insecurity underwater.In conclusion, Crystal Diving is an excellent diving school where you can learn various diving courses accompanied by spectacular instructors.

Crystal dive was amazing, my instructors Katy and George were so helpful and took the time to help me when I struggled with a skill. We had Noah on our ocean dives and he also was so helpful. I can’t thank the team enough proably, wouldn’t have passed without their support!

Definitely recommended! My partner and I did PADI open water course with Crystal and it was really good. Tom and Austin were amazing! They were very attentive, patient, always explained everything in details. We felt very safe with them and they also made the whole experience a lot of fun. It was so much fun, we were very tempted to continue with advanced course as well, but had to move on, sadly (hopefully will be back!).Crystal is recommended - it is big, but you are not left on your own, or feel like noone cares. They are very attentive and organized. They also have their own pier which makes it faster and easier (we did not get to use it really due to weather, as we went to other bays. But it did not bother us, I was very glad to see other parts of the Island and they were very beautiful!).The accomodation was free for 4 days and it was a private room with attached bathroom. It was quite clean, comfortable, at the Crystal school - so very convenient for early mornings, only cold water (but it's so hot in Asia, we never use hot water anyway). No wifi by the way. There is AC, but we would not have used it had there been a mosquito net on windows (note to management - with mosquito nets guests will be able to open windows more and use AC less, good for environment and saves money for you, maybe consider?). Overall accomodation was good and also we got 4 days so it was not rushed.Overall the whole experience was amazing.

What an amazing few days ✨🐠🤿💫!!I decided to dive here at the recommendation of a friend, and I have zero regrets.Such a friendly atmosphere from all the instructors and staff alike. I did the PADI Advanced Open Water course here with two incredible instructors, Katie and Kelvin, who both made the experience unforgettable🙏🤩. The course was loads of fun and I was made to feel secure throughout the technical dives.I also joined my friend’s Open water course dives with his instructor. Ben was also amazing and so chill, he even lent his personal GoPro for me to film my friend’s first dive.The accommodation was offered free of charge with the padi course, though, despite this, was high quality. We had a clean room with plenty of space and an en-suite. It was also is a great location to make the most of nearby bars, etc…

Excellent school. I recently took the Open Water and Advanced Open Water courses at Crystal, and I must say, it was an impressive experience! The team at Crystal, Sandy, Michaella and Larissa provided a top-notch learning environment that exceeded my expectations. People at Crystal are very friendly to mingle with. Highly recommend.

Loved Crystal!!! Finished my 4 open water dives for certification with Claire Semple yesterday and today. She was awesome. Supportive, empathetic, clear headed and encouraging , Claire helped me fall in love with the sport. Our epic dives at Twins and White Rock today were breathtaking. Couldn’t have asked for a better teacher and buddy underwater. Worth a trip to Koh Tao for this experience. Unforgettable. Thank you, Claire and Crystal Dive!!!
