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 & relaxation. 

Just minutes from Natural Bridge KOA, campers enjoy rafting, fishing and ATV trails. Hike or horseback ride in the Adirondacks - or marvel at the region's beauty on a scenic kayak 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 NOW OPEN FULL SEASON (May 13 - Oct 17) <<
