Welcome to the Natural Bridge / Watertown KOA

Two of New York's finest vacation areas - the Adirondack Mountains and the Thousand Islands - practically meet right at your site when you set up camp here. Roomy, shaded sites are set under a canopy of mature trees. Take a spin around the campground in an old fashion wagon ride, join in on the fun-filled theme weekends, and slip into our heated indoor pool for some all-weather play & chill. Just minutes from this KOA, campers can enjoy rafting, fishing and ATV trails. Hike or horseback ride in the Adirondacks - or marvel at the region's beauty on a scenic train ride. Tour the grand Singer and Boldt castles or join in one of the boat excursions that weave among the lovely Thousand Islands. Pool is open all season. Max pull thru: 65 feet (but keep on the watch for longer site upgrades!). Your hosts: James & Stacia Madden.
