River Highlands State Park offers two primitive boat-in campsites on the Connecticut River, accessible only by canoe or kayak with a maximum one-night stay at $5 per person per night.

Each site features a fireplace and pit toilet, though campers must bring all drinking water and pack out all trash, with no mooring or docking facilities available.

Reservations are required and can be made up to 11 months in advance through ReserveAmerica; the park is open May 1–September 30.
