At the T-intersection, turn left; pass by the parking area for Loew's Theatre; at the end of the road enter the park.
Directions to the Palisades Park section of the Park:
Keep heading east on DeGraw Avenue Teaneck Road and turn right onto Grand Avenue. Drive about 1.1 miles and turn right onto Roosevelt Place (at the sign for the park) and head to the end of the road and into the park.
