Super nice experience at dive concepts on Lembongan! Thanks to Kaka, Leah and Emma I got my Open Water certificate. It was educational, but above all very pleasant. The underwater world was beautiful and we saw a lot of beautiful things. In between dives relax on the boat. The material was good and everything was finely arranged. Definitely recommended if you want to learn to dive and have a good time

I took the Open Water Diver course and it was a fantastic experience. The atmosphere at the diving school is very nice, the equipment is well maintained and the organization was well organized to perfection. We were taught in a small group with very personal guidance. Kaka, Emma and Leah were enthusiastic, experienced and professional and especially made us feel at ease. The dive sites were phenomenal with beautiful fish and marine animals. All together it was an unforgettable experience and I would definitely come back here again.

Loïc and Tiziana were very reassuring, attentive and always encouraging. Loïc explains the instructions in a clear and accessible way, which helped me a lot. I couldn’t have dreamed of better accompanists. Many thanks to both of them for their support throughout my Open Water training! Skates, turtles and countless fish are beautiful, the diving points are exceptional.

I completed my SSI Open Water Diver certification on Nusa Lembongan, and it was a fantastic experience from start to finish. A big thank you to Silvère, who led the entire course. He is an excellent instructor – calm, patient and very professional. He explained everything clearly and made sure everyone felt safe and confident underwater. As a beginner, that made the learning experience really comfortable. After finishing the course, I also joined a fun dive with him, which was a perfect way to enjoy the beautiful dive sites around Lembongan. Another highlight were the boats – they are spacious, comfortable and very well organized for the dives. The certification is also officially registered through the SSI system and available in the SSI app, which makes it easy to access your certification anytime. The whole team was friendly, professional and very well organized. I can definitely recommend this dive center if you want to do your SSI Open Water course or fun dives in Nusa Lembongan. Thanks again to Silvère and the whole team for an amazing diving experience!

Great experience with Dive Concepts Lembongan. I spent Open Water training with them, and I loved it. Silvère was a very good instructor, calm and pedagogue. Tiz, who was accompanying her in future dive master, was also at the top. I recommend 100%!

I passed my open water course today with Dive Concepts and i honestly don’t have one bad thing to say. My dive masters were Silvere and Tiz, they provided the most support when needed and answered every question I had. They have a high level of expertise so when completing your first dives I felt extremely confident and comfortable. I couldn’t recommend this dive center enough if you’re looking to dive in Nusa lembongan!
