StandoutExceptional marine biodiversity

Waterfall Bay in the Similans offers a relaxed dive, usually a nice drift along a gently sloping reef. We often spot leopard sharks resting on the sand patches, and the bommies are home to plenty of angelfish and parrotfish. It’s a good spot for newer divers, or anyone looking for an easy second dive, with depths usually staying around 15-20 meters. You’ll find some decent hard corals, a pleasant reef to cruise over.
