Could not recommend Crystal Dive enough! Planned on doing our open water certification but in the end stayed to do our Advanced certification as well. Our instructor Perry was amazing. So nice and patient and really put a good feel factor with every dive. Also had instructor Glenn join us on our Advanced cert who also added so much to our experience. Have fallen in love with diving

I did my Advanced Open Water + Nitrox certifications there with George C. in April 2024 and I had a great experience! Staff is cool and George was an excellent instructor, always putting safety first.Definitely recommended!

I’d really recommend this diving school. I did my PADI open water, and they really take the time to teach you how to do scuba diving. The accomodation was included, which was convenient. First you practice in the pool with all important skills before getting into the sea, which was a good way of learning and to feel comfortable. Groups are small which was also a plus. Tom was a great instructor, very experienced, thank you! 🙏🏼

Me and my partner did the open water course with Crystal Dive after a recommendation from a friend. No previous diving experience. We were very pleased with our experience. Vic, our instructor made us feel comfortable from start to finish, and with his training we felt confident in the water and thoroughly enjoyed the experience. Thanks Vic 🤙🏼🤙🏼The accomodation is basic, (needs a little more attention to cleaning) but it was included and was lovely to have a private room and bathroom and be so close to the beach and obviously the dive course.

We did our open water padi with crystal dive and it was fantastic. A four day course with four day free private accommodation. The site is on the beach so no need to walk far with the heavy bags either. Our instructor Tom was really helpful and friendly. Would definitely recommend.

Finished my Openwater with Crystal and had Ana amazing time. Melanie was such a great teacher and not only taught us everything but was pointing out interesting and cool fish whilst diving in the ocean. Even fought off a triggerfish for the group.Also a huge thank you to Mathijs would lead me to complete my Advanced course. An amazing time diving in some very unique and beautiful dive sites.

My boyfriend and I completed our open water diving certification last month and it was truly one of the most amazing experiences I have ever had. At first I was unsure whether I should get my diving license because I can't swim particularly well. However, after speaking to our instructor George, I felt very motivated and encouraged to give it a try. George was always helpful and supportive when I had questions or concerns. Thanks to its clear communication underwater, I always felt safe. He really is an excellent diving instructor and puts a lot of emphasis on us learning the important skills correctly. Celine, who is currently doing her divemaster, was always there to support and help us. Thanks to George and Celine we had an unforgettable experience. I can highly recommend the diving school and especially diving instructor George!

I fell in love with diving here. Originally my intention was just to take the Open water course but enjoyed it SO much that I ended up taking the Advanced Open water, Nitrox and Wreck specialty followed by the Rescue course.I felt super comfortable breathing under water from the get go. Even when I struggled a bit with one skill, our instructor Bo helped me build the confidence to do it successfully.He is super engaging, easy to understand and is a lot of fun - a top notch educator.Class ratios were super safe with 4 students to 1 master instructor and 1 assistant.It’s worth mentioning that Crystals Open water course is over 4 days versus 2.5 at some other schools which was a deciding factor.I’m stoked to travel all over Southeast Asia and dive some of the world’s best sites now equipped with PADI specialty certifications!If you’re looking for a life changing experience look no further than Bo at Crystal Dive!

The open water course at Crystal Dive is definitely recommended. Had a great four days. Mathijs was our instructor and we couldn't have asked for a better instructor! Mathijs takes all the time to give you a nice, familiar and confident feeling under water! Crystal Dive's service is also top notch. We liked the open water course so much that we immediately opted to take the advanced course
