My experience with Crystal Dive Koh Tao was absolutely great! I originally came to the island for a refresher and some fun dives but was immediately convinced that this was the perfect place for my Advanced Open Water course. My instructor Melanie was professional, extremely thorough, knowledgeable and shared many tips for diving and the island. I really enjoyed every single dive and learned so much through her. I especially loved the perfect buoyancy dive and the sail rock dive! I felt very safe and cared for during my entire course. The atmosphere in the team was great, and the instructors clearly sparked the passion for diving of both students and fun divers. I'll surely come back and maybe even complete my Dive Master course with Crystal!

Did my basic diver experience with Crystal Koh Tao and very happy that I did it with Kelvin who was amazing, he helped me feel very comfortable and reduce my stress for my first dive ! I felt very safe from start to finish with all the processes and will recommend it to anyone who wants to have a good experience !

Did my SSI divemaster with crystal and really enjoyed the experience. The program was designed in which I got to improve my skill and knowledge in diving, also to experience and learn about teaching diving and interacting with students and real clients. The instructors are very knowledgeable and attentive, they are ready to help you if you have questions. It was also super lovely to be able to meet and spend time with the fellow dive master candidates there, we got to do a lot of fun dives together during our training, many beautiful memories created.

I had the best time diving with Crystal! The centre is perfectly located on the beach with great accommodation on site. The staff members are all approachable, kind and professional which is really important for someone like me who was completely new to diving. Kelvin was my instructor for both my open water and advanced and he made the whole experience unforgettable. What can I say he was patient, super knowledgable and struck a perfect balance between fun, laid back but still super professional. Ciara was assisting us throughout both our OW and advanced courses and she was amazing!! She was always positive and bubbly and was a great addition to the group, she made the whole experience really fun!😊 We got photos taken by Vicky and couldn’t be happier with how they came out - so would highly suggest paying extra for that as it’s a memory you can cherish for life! Thanks again Crystal, until next time!

I did my Open Water course with Kelvin and am very excited! I was a little afraid beforehand, but the first day in the pool took my fear away completely, it's so cool what's possible! And diving is a lot easier than I thought. The small groups are great, but on the boats it can get a bit stressful because many groups start at the same time. On the first day in the sea you still have to practice a lot of skills, on the second day you are a little freer in diving and can relax more.The accommodation was free, great offer!

Really enjoyed my crystal dive experience with Michaella, she really put the effort to make sure we learnt everything and was very considerate, making sure equipment was clean also. Was so much fun, my open water course was also very good with Nina. 🤙👌😍 I imagine it is the case for all dive sites but only issue I found was the snorkel sometimes wasnt very clean with little time to clean that yourself before use. May be a good idea to provide soap so we can clean the goggles etc. ourselves before diving.

Was so lucky to have Michaella as my diving instructor for both the open water and advanced courses. This was my first time diving and I always felt absolutely safe underwater with her as the instructor. In only five days, my dive buddy and I, became super comfortable in the water with all the gear and we had so much fun. I have I only great things to say about this experience. An absolute highlight of my trip 🙏🏼🙏🏼🙏🏼 thanks!

had an incredible experience at Crystal Dive Koh Tao, completing both my Open Water and Advanced courses with them. A huge shoutout to my instructor Evan, who made the entire journey smooth and enjoyable. As someone who isn’t a great swimmer, I was quite nervous at first, but Evan’s patience, clear instructions, and calm demeanor kept me feeling safe and confident throughout. The professionalism, friendly atmosphere, and top-notch training at Crystal Dive made it an unforgettable adventure. Highly recommended for beginners and experienced divers alike!

Oh my god! olalalala! sacrebleu! Oli, George, Anna, Mimi,Johnathan, James, Tod, Tom, Claude, Anna&Evan, Na, Neils, all the people on the boat and everyone at Crystal Dive I forgot to mention but I keep in my heart! Thank you! I’m not going to say how good were the lessons and the teaching and the gears and the professionalism because it’s been said over and over again, but what I’ll say is : we cried for our rescue because it was tough! But also, we laughed, and we laughed, and laughed some more. And it was… great? Amazing? Of course it was… and one day we leave on that stupid speedboat and life has to carry on, but you’ll leave a tiny piece of you there.I wish to all of you all the best, and may everyone that come to learn with you have has much fun as we did!

Did my SSI advanced here with Kelvin. Top instructor with a lot of expertise, good explanations, loads of patience and luckily just a nice guy. He also maintains a good balance between learning moments and enjoying the dive. Crystal is also an excellent diving school. Material could use an update.
