The Wallkill Valley Rail Trail is a 23.7-mile (38.1 km) rail trail and linear park that runs along the former Wallkill Valley Railroad rail corridor in Ulster County, New York, United States. It stretches from Gardiner through New Paltz, Rosendale and Ulster to the Kingston city line, just south of a demolished, concrete Conrail railroad bridge that was located on a team-track siding several blocks south of the also-demolished Kingston New York Central Railroad passenger station. The trail is separated from the Walden–Wallkill Rail Trail by two state prisons in Shawangunk, though there have been plans to bypass these facilities and to connect the Wallkill Valley Rail Trail with other regional rail-trails. The northern section of the trail forms part of the Empire State Trail.
