Selden Neck State Park offers four primitive boat-in/boat-out riverside campsites along the Connecticut River on a 607-acre island accessible only by water.

Each campsite includes a firepit, picnic table, and outhouse, with downed timber available for fires, though there is no potable water, docking, or mooring facilities.

Reservations are required and cost $5 per person per night for one-night stays between May 1 and September 30, with all visitors required to depart by 8 p. m.
