5.00Awesome time, we stopped at 3 locations on the reef. We booked the introduction to scuba and we got to dive 2 times, the first dive was learning what to do and the 2nd dive was 50 minutes of just exploring while scuba diving. Very very fun, our instructor was awesome. The ride out to the reef was about an hour and a half, take sea sick tablets if you get sick because you lose sight of land for a large chunk of the ride.

5.00Already at the reception, the staff was charming, very professional and gave a good and smiling feeling. The messages were short, to the point and with humor. It seems that the dynamics between the staff members are very good, which gave us the guests a good experience. Even in the water, explanations were given by the expert Hadar. The lunch was wonderful and satisfying, especially for a vegetarian like me. Highly recommend everything. It was a unique and unforgettable day.
Fantastic day out
