New York's of trail contain very little elevation change compared to other states. It is rather rugged terrain nonetheless, with many short though nearly-vertical ledges and small cliffs. From south to north, the trail summits many small mountains under in elevation, its highest point in New York being Prospect Rock at , and less than half a mile (800 m) from the border with New Jersey. The trail continues north, climbing near Fitzgerald Falls, passing through Sterling Forest State Park, and then entering Harriman State Park and Bear Mountain State Park. In Harriman State Park, the trail passes through the famous Lemon Squeezer, a narrow crack between huge boulders. At Bear Mountain State Park, it goes through the park zoo, where the lowest point on the entire AT, at above sea level, is located in front of the bear cage. Immediately afterward it crosses the Hudson River on the Bear Mountain Bridge, then climbs into Hudson Highlands State Park where it follows a ridge over several low-elevation peaks. It then passes through Fahnestock State Park and continues northeast and crosses the Metro-North Railroad's Harlem Line at Pawling, which is also the only train station along the length of the trail. It enters Connecticut via the Pawling Nature Reserve. The section of the trail that passes through Harriman and Bear Mountain State Parks is the oldest section of the trail, completed in 1923. The Appalachian Trail in New York is maintained and updated by the New York-New Jersey Trail Conference.
