Because Gab Gab beach is located on the US Naval Station, this very easy beach dive is accessible only if you get clearance to dive on the base. Otherwise, a boat dive is the only option.
The dive offers an abundance of corals and sloping reefs. Anemones and various invertebrates dot the coral reef, which also offers good hiding places for turtles. This also makes a good night dive, as entry and exit are quite easy and conditions usually mild.
