The trail is supported by the New York State Department of Environmental Conservation (NYSDEC), the Taconic Hiking Club, the Trust for Public Land, the National Park Service, Williams College, Rensselaer Land Trust, the Massachusetts Department of Conservation and Recreation, and the Williamstown Rural Lands Foundation.

From Berry Pond, the trail descends the ridgeline into the village of Hancock, Massachusetts, then ascends the second ridge, which straddles the New York border.

The trail follows a series of high, open summits and ridgeline overlooking the Hudson River Valley to the west.

[1] Overnight camping is allowed on the trail; a seasonal campground with facilities is located at Berry Pond.

The Taconic Crest Trail originally extended 29 miles (47 km) from Berry Pond in Pittsfield State Forest to North Pownal, Vermont.
