Campgrounds and RV parks near Great Bend, NY

Boating, fishing, and paddling drive most trips to this area. The St. Lawrence River fronts several nearby state parks, with boat launches and dockage at Keewaydin State Park and Kring Point State Park, and marina slips available at Swan Bay Resort and Marina. Anglers target smallmouth bass, northern pike, walleye, and muskellunge across Goose Bay and the main river channel. Families typically pair river time with the region's landmark attractions: Boldt Castle on Heart Island, Singer Castle, boat tours out of Alexandria Bay and Clayton, and the Antique Boat Museum. Sackets Harbor Battlefield, on Lake Ontario, covers the War of 1812 naval history that shaped this stretch of the border. Inland, the Natural Bridge / Watertown KOA Journey area puts riders and hikers within reach of ATV trails and the western Adirondack foothills.

The practical RV season runs from late April through mid-October. New York State Parks in the Thousand Islands cluster follow this pattern, with Kring Point State Park open from the last Friday in April through Columbus Day, and Grass Point State Park and Keewaydin State Park operating on similar spring-to-fall schedules. Keewaydin State Park's marina operates May through October, with ice fishing and cross-country skiing available in winter, though its 48 campsites are seasonal. Summer is peak. July and August bring the warmest weather, longest daylight, and the highest demand for waterfront sites. Weekends at the state parks fill early, so bookings well in advance are standard. September delivers cooler nights, thinner crowds, and reliable fishing, and is often the best value window for flexible RV travelers. Winters are cold and snowy, driven by lake-effect systems off Lake Ontario. Most private campgrounds close for the season. Natural Bridge / Watertown KOA Journey itself operates from mid-May through mid-October, so winter travelers should plan on off-site lodging or dry-camping options elsewhere.

State park sites in this corridor are typically wooded or open riverfront pads with a picnic table and fire ring. At Kring Point State Park, about half of the 100 campsites sit on the waterfront, individual sites do not have water or sewer hookups, and shared water spigots are located throughout the loops. Showers and a dump station are on-site, and a portion of sites offer electric. Keewaydin State Park has 48 campsites overlooking the river, plus an Olympic-sized swimming pool, marina, showers, and a dump station, though sites do not have individual hookups. Big-rig RVers often prefer private grounds for full hookups: Natural Bridge / Watertown KOA Journey offers full or partial hookup sites with pull-thru access, 20/30/50 amp service, laundry, a dump station, and an indoor heated pool. Exposed riverfront sites can get windy, so awnings should not be left extended when the site is unattended.
