A.T. Detour at Harriman State Park

May 9, 2022

Appalachian Trail & Ramapo-Dunderberg Trail:
Detour in effect at Harriman State Park

 

To avoid a major road crossing of the Palisades Interstate Parkway (NOBO mile 1,399.5) in Harriman State Park, New York, a section of the Appalachian Trail (A.T) and Ramapo-Dunderberg Trail will soon be closed, and a temporary detour put in place. While this detour has not yet been fully blazed, hikers are encouraged to follow the detour as shown on the map linked below to cross the Parkway via the Anthony Wayne Overpass. We will update this post when the closure of the current A.T. route over the Parkway has been fully implemented and the detour is in full effect.

 

This temporary detour is in effect until a permanent route is determined by State Park staff.
