Can’t recommend Crystal diving enough! Me and 2 friends did our discovery diving and open water courses here and it was such an amazing experience. This was the first time any of us had used scuba gear but thanks to our instructors, Kelvin and Claire, we felt at ease from the off and quickly became comfortable underwater. They were also extremely knowledgeable about the dive sites around Koh Tao meaning that we were in the right place at the right time to see some amazing corals and marine life (special mention to the huge hawksbill turtle we swam with on our very first trip!).

I was lucky to book with Crystal Dive when i was in Koh Tao and even luckier to get Bo as my instructor.I finally wanted to see the inside of the wreck and did my Padi "wreck diving specialty" with them. They were the only Center that really provided what others only promised: in two days, starting very spontaneously the next day, they were able to deliver the course for me.It was very special inside the wreck und made me happy - a good moment in life! Thank you.Bo as an instructor is laid back but at the same moment very professional - he knows what he is doing - so i felt likewise very laid back, which made the experience great and calm.I can highly recommend Crystal and Bo!

Had an amazing experience with Crystal Dive on the discovery dive. First time using scuba gear, Kelvin and Claire made us feel safe while showing us some awesome reef systems and marine life. We felt informed and the vibes were always good. Signed up for the open water certification upon arriving from the dive. Highly recommend for anyone traveling to Koh Tao!

I went scuba diving for the first time today. We booked the Discovery class and it was incredibly fun. There were three of us and we had two instructors: Kelvin and Claire. They were both really nice, made us feel calm, and gave me a super safe feeling while diving. I had so much fun that I signed up for the diving certification right away. Thanks!

Had an amazing experience with Crystal Dive!! George was so welcoming when we first arrived and gave us great recommandations of things to do on the island. Sandy and Jonah, who were our instructors, were extremely nice and patient with me during the Open Water dive course. They made sure I felt comfortable every step of the way and helped me overcome my fears! I loved my experience. I would 100% recommend this diving center. Thanks again for everything! 🙂

3 months ago, we discovered diving with you while passing our Open Water. We were fortunate to have two instructors for every three students. Everything was perfect: serious, complete practice in the pool before practicing at sea, top equipment, super cool atmosphere on the boat: a great learning experience which completely gave us confidence. Thanks to this we are at 40 extraordinary dives between Thailand and the Philippines >>> thank you Crystal Dive (Kosro and Honey)

So, last Summer (2023), I did my Advanced at Crystal and six month later I came back to do my Divemaster. Everyone at Crystal is so professional and friendly. Really recommend it if you’re looking for a fun dive school with high safety standards. Will definitely come back (again)!

Scuba diving was not something I planned on doing on my trip but I am very glad I did. The whole team at Crystal dive were excellent!I did the open water course with Kelvin (and Jonah) as our instructor and had an amazing time. I was a little nervous about some of the skills we needed to perform but Kelvin was super patient and reassuring while making sure everyone was okay and having fun - couldn’t recommend any more!:)
