Hanauma Bay

This "Curved" bay was declared a protected marine life conservation area and underwater park in 1967.
This is THE BEST protected cove if you are new to scuba diving or snorkeling with a diverse population of marine life and a large, rich coral reef.
Advanced snorkelers and divers can also enjoy the beauty of this bay as the reef extends throughout the cove into deeper water.
The bay floor is actually the crater of an ancient volcano that flooded when the exterior wall collapsed and the ocean rushed in.
