National Park Service · New York
A 26-mile barrier island off Long Island where the best parts, the globally rare Sunken Forest and the Otis Pike Wilderness, are reached only by a seasonal passenger ferry across the Great South Bay.
Field briefing
Fire Island National Seashore starts with access, not mileage.
Before you go
From late May to early October, two passenger ferries cross the Great South Bay: Sayville to Sailors Haven for the Sunken Forest, and Patchogue to Watch Hill for the wilderness. There is no entrance fee, but you pay to park at the mainland terminal and for a round-trip ferry ticket, and you should confirm the seasonal schedule and the last return run before you go. The Fire Island Lighthouse end is the exception, reached on foot from Robert Moses State Park without a ferry.

Weather, crowds, and what the season changes about the trip.
Cool and breezy with highs in the 50s and 60s, ferries starting up in mid to late May.
Pack Windproof layer, closed shoes for cool boardwalk mornings, and a check of the ferry start dates.
Warm and humid, highs in the 80s, strong sun on open beach and biting insects in the marsh.
Pack Sun shirt, hat, plenty of water, and insect repellent for the Sunken Forest boardwalk.
Mild, clear, and often the best beach weather, with ferries tapering off through October.
Pack Light layers, a wind shell for the ferry crossing, and a confirmed return-trip schedule.
Cold, windy, and quiet, with no ferry service and minimal facilities. The boardwalks stay open but you must walk in or boat in.
Pack Full wind and cold protection, and a plan that does not depend on any island services.
Sunken Forest
A globally rare maritime holly forest tucked behind a double dune, with 300-year-old hollies. Reached by ferry to Sailors Haven, then a level boardwalk loop.
Watch Hill
The other ferry-served hub, with a marina, a marsh boardwalk, the only car-free lifeguarded beach, and the gateway to the wilderness.
Otis Pike Fire Island High Dune Wilderness
New York State's only federally designated wilderness, seven roadless miles of dune and beach east of Watch Hill, hiked along the open shore.
Fire Island Lighthouse
The 1858 black-and-white tower near Robert Moses State Park, reached on foot along the beach or boardwalk rather than by ferry.
Put permit timing ahead of ambition, then build the route around what is actually approved. For one day in Fire Island National Seashore, make Sunken Forest the non-negotiable, add Watch Hill only if the first stop runs clean, and keep Otis Pike Fire Island High Dune Wilderness as the flexible finish.

There is no NPS lodge or developed drive-in campground at Fire Island, and the island communities are car-free. The one in-park overnight option is backcountry camping in the Otis Pike Wilderness, which needs a free permit and is hiked in from Watch Hill. Most visitors base on Long Island in Sayville, Patchogue, or Bay Shore near the ferry terminals, or stay in one of the private Fire Island community rentals served by the commuter ferries. Watch Hill has a small concession-run campground reached by the Patchogue ferry, reserved separately through the concessioner.
Camping reservations
Fire Island has no road-accessible NPS campground. Watch Hill offers a small developed campground reached by the Patchogue ferry and booked through the concessioner, and the Otis Pike Wilderness east of Watch Hill allows free backcountry camping by permit. Everything else is mainland lodging or private community rentals.

Getting there
Arrival note
Fire Island sits just south of Long Island, separated by the Great South Bay.
Transfer plan
There is no bridge to the central communities, so most visitors drive or take the Long Island Railroad to one of the bay-side towns, Sayville for the Sailors Haven and Sunken Forest ferry or Patchogue for the Watch Hill ferry, then cross by boat.
Car strategy
The Fire Island Lighthouse and the eastern Smith Point end are the two car-accessible exceptions, reached through Robert Moses State Park and the William Floyd Parkway.
Pair this with lodging: the best base is the one that protects the departure window, pickup point, or weather buffer.
For the best-known parts, yes. The Sunken Forest at Sailors Haven and the Otis Pike Wilderness at Watch Hill are reached only by seasonal passenger ferry from Sayville and Patchogue. The Fire Island Lighthouse and the Smith Point area at the two ends are the exceptions, reachable by car.
No. There is no entrance fee. You do pay to park at the mainland ferry terminals and for a round-trip ferry ticket, which together are the real cost of a Sunken Forest or Watch Hill visit.
Yes, in two ways. Watch Hill has a small concession-run campground reached by the Patchogue ferry and reserved through the concessioner, and the Otis Pike Wilderness allows free backcountry camping by permit. There is no road-accessible drive-in campground.
The Sunken Forest is a globally rare maritime holly forest growing behind a double dune system, with American hollies up to 300 years old. You reach it by ferry to Sailors Haven, then walk a level boardwalk loop through the canopy.
