Hanauma Bay Nature Park is one of the more popular recreational swimming, snorkeling and picnicing areas on Oahu. This sunken volcanic crater is a snorkeler's paradise, with thousands of tropical fish and other marine animals, a few turtles, and a pristine coral reef in fairly shallow water, at most 20 feet deep.

This is the very best beach area if you are new to Scuba diving or snorkeling with a diversified population of fish and a rich coral reef.
