North of Manhattan are several large patches of wilderness in the lower Hudson region. Among them is Harriman State Park, a wonderful network of hiking trails featuring a commuter train stop near the trailheads on the southeast and northwest sides of the park. It is the largest parkland near NYC that allows camping, yet it is often quite sparsely utilized by city dwellers.

Among the trails is the Long Path that runs from the New Jersey side of the George Washington Bridge in Fort Lee, and weaves 350 miles north (564 km) to Albany NY. For anyone who finds that jaunt too short, Harriman is also intersected by the infamous Appalachian Trail that spans 2175 miles (3500 km) from Maine to Georgia.
