Lighthouse Beach

Lighthouse Beach is a small section of the Fire Island National Seashore that is adjacent to Robert Moses State Park on New York's Long Island. It was notable for having sections that were officially designated as clothing optional prior to 2013.

The beach is named for the nearby Fire Island Lighthouse and was formerly the largest recognized clothing optional beach in New York. On 5 February 2013, the Fire Island National Seashore announced its plan to begin enforcing New York State anti-nudity laws on all Fire Island beaches, including Lighthouse Beach, ending clothing optional usage. However, the decision does not change the official status granted for the practice of female toplessness, which is still allowed.
