Nude Beaches--Legal or Not?

There are no legal clothing-optional beaches on Oahu but guys still manage to find someplace to go naked.  You may be able to find a secluded beach or cove somewhere but you should proceed at your own risk.  Oahu also has the largest police presence in Hawaii.   From time to time, police do patrol unofficial nude beaches and can arrest or ticket nude offenders.  Wearing something that completely covers your genitals is advisable.
