Lewis A. Swyer Preserve

At the Lewis A. Swyer Preserve, 120 miles up the Hudson River, the daily tides change the fresh water level in Mill Creek by more than four feet. Frequent flooding of the adjacent flat land has created the freshwater tidal swamp that is one of only five in New York State. This site features a half-mile boardwalk that leads visitors through three natural communities: a freshwater tidal swamp, a freshwater tidal marsh and freshwater intertidal mudflats. Ever-shifting tides reveal different secrets of the preserve with each passing season, and diverse species flourish in and around the swamp’s waters. The Swyer Preserve is owned and managed by the Nature Conservancy.
