As a first time diver, I felt in safe hands at Crystal. Kelvin, my instructor, was very patient and instantly made me feel at ease. My first ocean dive is an experience I'll never forget- thanks again Kelvin!

I did the Open Water and Advanced course, and I find Crystal dive an amazing diving school for multiple reasons:- Professionalism: They are very thorough with explaining the principles of diving, how and why you need to do certain things, and they have very good equipment. I would advise you to do the in person theory classes as they give you a better understanding of the diving principles, although if you have less time, an elearning option is also available.- Safety: They create a safe environment. I felt at ease during the whole course.- Staff: My instructors Alex and Maria are amazing. They created a safe and fun environment. The groups are small, and for my advanced, I even had Alex as a private instructor.Thanks a lot 🙏

Great diving school with an ideal location, especially to the harbor.Diving instructor Melanie was great! I can only recommend her because of her calm and trusting nature. Learning to dive at Crystal Dive/Melanie felt very safe and was a lot of fun.The room that was included was okay but not luxury.

I went to Crystal dive to get my open water qualification, I loved it so much I ended up getting my advanced a day later. My instructor, Tom Schluter, was super encouraging and made learning the skills fun and easy. I highly recommend Crystal dive to new and advanced divers, awesome environment and awesome experience.

The diving school is right by the sea, the school's boat has the best berth and the team is super nice. Mayo, our diving instructor really impressed us. Even though he was only 21 years old, he led us through the course with the utmost professionalism. He was the perfect teacher from A-Z. Safe, competent, “strict” and funny at the right moments.Thanks Mayo! We liked being your ketchup.

I arrived at Crystal for my rescue course and left an Instructor.Oli was in charge of my divemaster training and was a very good teacher.I worked there for a short time then did my IDC.I did it with Bob and he was awesome. He really gave us tons of material to nail our exam.But beyond a good preparation, I really felt he cared about us (the students) and this made all the difference.Overall Crystal was a very nice place. They succeeded in creating a very social environment through well organized snorkel tests and other events.The shop is well managed and equipped. They provide computers for everyone which is not the case with every dive shop.They also do a great job at following the standards for their courses, which is a very safe thing.I totally recommend this place.

Thanks to Cat & George, for giving us our first dive experience! They made the training fun and engaging and the time out at the ocean was great. We was worried about spending a whole day doing this activity with us only on the island for 3 days but it was so worth it!

Did my PADI advanced open water here. Was a fairly experienced diver with 30 dives already gained a lot from the experience. They had mostly all the elective dives for advanced diver available. I did the course with Alex and George and both were great. Crystal Dive was also super helpfully flexible - I was sick with a cold one day and was able to delay the rest of the course for a day. The boat was great too.
