I can't think of the name of the beach, but the natives would be able to tell you. It's on the Eastern shore of Oahu, past Diamond Head. It's in a crescent shape, and so far down from the parking lot, that they have trams to take you down. We're too old to do snorkeling, but this almost gives me the courage to try. Crystal clear blue waters with many varieties of fish. The other place that I've heard many people rave about are the green turtles that you would take from Maui. Have fun. Wish I was going with you. We were just in Hawaii on a 2 week land trip. We love it there.
