Awful for scuba...very shallow all the time and long way out, Just OK for snorkeling,no shells,only small fish near ends of cay.It is a small cay.We found much better waters and beaches in south Eleuthera.
As commented, this Cay/beach is indeed shallow; perfect for young children to snorkle. While our 5 year old caught crabs at the waterline, our 8 year old easily swam to and explored the "island" 50 yards offshore. Plenty of fish, sea fans, brain coral, and more. Shaded parking too.
