Campgrounds and RV parks near East Hampton, NY

East Hampton sits on the South Fork of Long Island, about two hours east of New York City by Sunrise Highway (Route 27). RV travelers use the town as a base for Atlantic beaches, protected bays, and the maritime woodlands that stretch east toward Montauk Point. Camping options are limited within the town itself, so most visitors reserve at state parks and private grounds along the South and North Forks, or across Long Island Sound in Connecticut. The closest oceanfront camping is Hither Hills State Park, a large New York State campground on the Atlantic between Amagansett and Montauk. Eastern Long Island Kampground sits across Peconic Bay on the North Fork near Greenport, a shorter drive but a different coastline. For travelers arriving by the Cross Sound Ferry from New London, Rocky Neck State Park and Niantic/I-95 Exit 72 KOA are common stops in Connecticut, and Aces High RV Park serves the same corridor in East Lyme. Expect strong summer demand, seven-night minimum stays at the most popular sites, and short shoulder-season windows in spring and fall.

State park sites on Long Island and in Connecticut are reserved through ReserveAmerica. For New York State parks, camping reservations can be made up to nine months in advance. Same-day reservations are allowed until 3 p.m. on the day of arrival, and walk-ins are permitted on campsites only. For Hither Hills, popular summer weeks sell out within minutes of the release. Create an account in advance, save preferred dates, and be logged in right when the nine-month window opens. Out-of-state fees apply, so residency affects the nightly rate. Private grounds such as Eastern Long Island Kampground, Niantic/I-95 Exit 72 KOA, and Aces High RV Park take reservations directly through their own websites or, for KOA, the KOA network. Book private grounds early for July and August weekends and watch for cancellations if the initial window is full.
