The Wallkill River National Wildlife Refuge is a 5,000 acre tract that straddles the New York/New Jersey border at Orange County, N.Y., and Sussex County, N.J. It was established in 1990 primarily for the preservation of wetlands. It is home to migratory birds and waterfowl as well as the endangered bog turtle. The Appalachian Trail runs through the refuge. Best access is via the 2.5 mile Liberty Loop trail that starts in Pine Island, N.Y.
