Clubs for people who like to be nude usually have nude swimming. These are usually called naturist clubs or naturist retreats. A retreat is like a camp or park. It is usually away from the city. Many years ago they were usually called nudist clubs. The name nudist club is less common now. If there is enough space, the club may have other nude sports. They sometimes have nude volleyball or nude basketball. They sometimes have nude soccer (football) if they have a big space. Sometimes people use boats without clothes. People sometimes use a sailboat, rowboat or canoe nude. Sometimes a camp or retreat owned by a church has nude swimming or other sports.
