Had a blast completing my PADI open water diving course which I completed in 4 consecutive days! If you’re short on time, you can definitely complete the course in 2-3 days 👍🏻 Read More

Ahmed  Elbedwihy

I had 2 weeks off and decided to do my open water with Nemo. I really loved the experience with the team as they really made me feel like I was family more than just a customer. The instructors are amazing, always shared their insight and were just all around great.. Read More

Ranwa Zahr

Can't recommend this team / place enough. Did my Open Water, Advanced Open Water and now doing Rescue certification with them. Walked in to the place a bit shy and reserved as I had a very healthy fear of Open Water, and didn't quite know what to expect. Read More

Karim and the team made our day; they knew exactly where to find turtles and never rushed us. I felt completely safe and had so much fun!
