The south town line is the border of New Jersey, and the west town line is the border of Orange County. The break in the Ramapo Mountains at Suffern formed by the Ramapo River causes the town to be the site of the New York State Thruway and I-287, New York State Route 17, and a railroad line. The Palisades Interstate Parkway runs through the northeast corner of the town, with an exit at the Haverstraw town line on the northern border.
