Cupsogue Beach County Park is a 296acre park at the east end of Fire Island and the west end of Westhampton Island, known locally as Dune Road, one of Long Island's easternmost barrier islands. The park is surrounded by the Atlantic Ocean, Moriches Inlet and Moriches Bay.LocationThough the park exists on both sides of the Moriches Inlet and is located entirely within the Town of Brookhaven, it is only accessible from the western terminus of Dune Road, which itself is in the Town of Southampton. The closest bridge to the park is for Jessup Lane in the village of Westhampton Beach between Moriches Bay and Moneybogue Bay. The park's eastern border is the Brookhaven/Southampton town line and the village of Westhampton Dunes.Park descriptionThis 296acre barrier beach park offers lifeguard-supervised swimming, sunbathing, fishing, scuba diving, and special events. A food concession, restrooms, first aid center (staffed by an EMT during the summer months), showers and changing rooms are all situated at Cupsogue's pavilion. Camping and recreational vehicles are permitted along the access road running parallel to the outer beach. Diving is permitted at slack tide on the bay side of the park only, where water depth is approximately 12ft.
