Had 2 fun dives with DM Alex. Friendly and guided us nicely underwater. Also he had his own camera so we got some photos and videos as well!

I did the Open Water Diver here spontaneously and without any previous experience. George and Todd were great.The whole staff is extremely friendly and helpful. The accommodation was included for the duration of the course, very spacious and absolutely clean.Overall a great experience. 10/10

I tried the Discover Scuba Diver here a few days ago, then did the Open Water and then the Advanced Open Water Diver. I usually don't feel comfortable when I can't see the bottom of the ocean and have never wanted to go diving. That's why the Discover Scuba Diver was spontaneous and initially just a challenge to myself. However, I enjoyed it so much and I felt so comfortable right from the start that I couldn't stop 😆The prices in Thailand are really unbeatable when it comes to diving.If you book a course, you have the opportunity to receive accommodation from the diving school for 300 baht per night for the duration of the course. We were also happy to accept the offer 🙂

I got both my Open Water and Advanced diving certifications here, and it was a truly amazing experience. From the first moment I felt at ease, and that was because of the fantastic diving instructor Bo. He explains everything very clearly and you can tell that he has been doing this with great pleasure for years.And not just Bo, the other staff and divers were also super nice. I really couldn't have asked for anything better. If you ever want to learn to dive, this is the place.

Just completed the open water diving course with Ben & Jonah! Unreal time, they were extremely safe and made us feel at ease throughout, whilst also making it really fun! Highly recommend choosing these specific instructors!

On our trip we really wanted to try diving and what better place to try it than on Koh Tao!We came to Crystal Dive based on a recommendation and were not disappointed. We started with a Basic Diver course to find out how we like diving. After the Basic Diver we were fascinated and definitely wanted to continue with the Open Water Diver and in Mayo we had the perfect diving instructor! Despite his young age, he is extremely experienced, professional, personable and always gave us a good feeling.Another plus point is that if you dive with Crystal, you get accommodation directly on site for free or at a reduced price!We actually wanted to do the Advanced Open Water with Mayo, but unfortunately we couldn't do it due to illness. Then unfortunately we were told that we had to move out because we didn't start any diving activities...We understand that the rooms should be reserved for divers, but we still found it a bit of a shame since we have already done the BD and OWD at Crystal and have also stated that we still want to do the AOW.It also didn't seem like all the rooms were fully booked so we couldn't have stayed another 2-3 nights to get healthy and start the AOW course. It's a shame that influenced our overall experience somewhat afterwards.Nevertheless, everything as far as diving was concerned was great and we will definitely go back one day to add the AOW!

Great overall experience learning diving at Crystal Dive in Koh Tao. Couldn’t have asked for a better instructor than Attila for the open water and advanced adventurer courses.

I completed my open water and advanced adventurer course here and had a great time while doing so, all the staff are friendly and helpful. I had Alex as my dive instructor who was a really chill and cool guy, even going out his way to rearrange my dive dates due to a sudden injury. I would definitely recommend this dive school

Very good diving club, location wise, right on the beach, they have their restaurant with the longest menu I've ever seen, I did the open water with Alex and the advanced adventurer with Kelvin, both are really good instructors, patient and always gave 100% of themselves.The course itself was very enjoyable, I wish it would've lasted a bit more 🥲I came with no experience underwater and it only made me hungry for more!Definitely recommend coming here

Crystal Dive is a very good diving school where you are simply introduced to the world of diving and everything is explained well step by step. My diving instructor was George with whom we had a lot of fun for 3 days.Price-performance is top you pay 11,000 baht and get a nice private room for 3 nights, including the Openwater certification and everything that goes with it!

Incredible dive school! Got my open water SSI certification there, lasted 2 days and a half and was great! I was instructor Alex, who was amazing, super clear instructions, patient and made sure we all felt comfortable.I highly recommend Crystal Dive, accommodation was included which is a huge plus to get to the pool and boat easily.
