Little Sister is a reef formation lying in 70 to 90 feet in water, in the middle of a large sand patch. Beautiful sponges and seafans home a variety of tropical fish . Huge lobsters, moray eels and of course the resident hawksbill turtle "Sissy" can be seeen there on most days. Only 10 minutes away from Simpson Bay.

Due to the depth, only fairly experienced divers will be allowed to dive there.
