I did my four open water dives with Submarine Diving School for my PADI licence and couldn't recommend them more highly. My instructor, Wisni, was very supportive and always on hand to answer questions. The whole team is very friendly and does a great job running the dive center smoothly.

Words can hardly express how comfortable I felt at this diving school. I completed my Open Water Diver certification here, having had no prior experience with diving. Consequently, my respect for the open sea was immense. However, I felt incredibly comfortable and safe at all times. Wisni is an amazing individual and instructor. He takes the time to explain everything in a way that is easily understandable. Truly, every single person at the diving school has left a lasting impression on me. Following the certification, I booked three more dives, and I will definitely come back for the Advanced Open Water Diver course. Thank you so much for everything!

This was our first Scuba Diving experience. Well organized team, you have to make a reservation before arrival and our instructor Mr. Sherly gave the full guidelines and we signed the paper before we start the session. Then they gave us a practical session before we jump into the deeps. We bought a GoPro camera for make out own videos. They provide only photos. Anyway it was one of my bucket list and its a life experience. Thanks for the team. Checkout the images under water beauty 🐠💙

Good and affordable diving shop with great staff. I took 5 dives and saw 1 shipwreck, 2 reefs and a 25 m deep sea trench. Prices are cheaper than other shops and these guys don't compromise on safety so check it out.
