Description: Alum Creek Beach, a state park beach on the southwest side of Alum Creek Lake, is the largest inland beach in Ohio. The sandy beach stretches just over a half mile. In Ohio nudity (exposed genitals) is illegal - so topless women and men in thongs will not get hassled by rangers. The thong and topless crowd stay at the south end of beach to avoid conflict with more fully clothed bathers. You may occasionally encounter fully nude bathers in the tall grass at the south end of the beach - but be discreet. This site is very popular with gay men.
