Overview
Established in 1964, Fire Island National Seashore stretches across 26 miles of the 32-mile long barrier island off the southern coast of New York’s Long Island. It encompasses 17 communities that were present when it was created, but otherwise it is mostly roadless and wild. Backcountry camping is allowed in the Otis Pike Wilderness (1,363 acres), the only federally designated Wilderness area in the state of New York.

Highlights
Fire Island Lighthouse, William Floyd Estate, Sunken Forest Trail, Otis Pike Wilderness
Must-Do Activity
About 2.2-million visitors come to Fire Island annually, but not necessarily to the National Seashore, which is primarily accessed by ferry boats from Long Island. A short walk down the coast can usually escape the crowds, but be aware that the area around Fire Island Lighthouse is an unofficial nude beach. Visitors can also tour the home and grounds at William Floyd Estate, a 613-acre historical site on Long Island once home to a signer of the Declaration of Independence.
Best Trail
There are nature trails at Fire Island Lighthouse, Sailors Haven, Watch Hill, and Fire Island Wilderness Visitor Centers, plus the beach is wide and good for walking.
