(CNN) — On the eastern end of Oahu, Hanauma Bay Nature Preserve offers a white sand coral beach enclosed in a breached volcano.
This marine-protected area, 10 miles from Waikiki Beach, was the first beach to ban smoking in Hawaii, a move to protect tropical fish in the area.
Dr. Beach, also known as coastal expert and Florida International University professor Stephen P. Leatherman, issues his annual list on the basis of 50 criteria, including water and sand quality.
He's recently started placing more emphasis on beach safety, environmental management and no-smoking policies.
Oahu bans smoking at all beaches on the island.
Hanauma Bay Beach Park has limited parking, so Dr. Beach recommends taking the Waikiki Beach Shuttle.
But don't try to visit on Tuesdays. The beach is closed to let the fish rest.
Hawaii took two of the top 10 spots in the annual rankings, but Florida had the most beaches listed with three.
North Carolina, Massachusetts, California, New York and South Carolina each had one beach in the top 10.
