WHAT our guests say

Divers Say

I've been on four trips with Simon, and all have exceeded my high expectations. These trips aren't just organised dive tours, there are always extra value activities planned in advance or negotiated on site. You'll always come back from one of Simon's trips a better diver and a better photographer, highly recommended
