There are several different types of nude beaches. Some are considered "Officially Recognized Clothing-Optional Beaches" where local authorities have set aside specific areas and marked them for nude bathing. Here it is totally legal to be completely naked, even though it is a public place. Other beaches that are not officially designated by local authorities can also be considered nude beaches, if the local populace and government have designated them so by tradition but not necessarily by law or signage. Some beaches that are usually considered to be the more traditional type where bathers where swimming apparel will also be lenient on allowing nudists to bathe naked, but that may depend on the part of the world the beach is located in and whether or not it is a family-friendly beach.
