This 275 acre Indian Island County Park, at the estuarine mouth of the Peconic River, is open to the public year-round for a variety of activities. Camping is immensely popular at Indian Island, with trailer and tent campsites open to organized groups, individuals and camping clubs. Restrooms and shower facilities are available for the comfort of all campers. What was formerly the "island" at Indian Island County Park is now connected to the mainland by a causeway composed entirely of white sands. Remote, yet easily accessible to all, this "island", complete with picnic tables, grills, comfortable benches and views of a glistening and peaceful Flanders Bay, offers one of the finest picnicking sites available in Suffolk County.
