The Whiteface Highway, also known as NY 431, begins at an intersection with NY 86 in Wilmington. The highway heads to the west, ascending in elevation as it approaches Whiteface Mountain. It heads through a pass between Morgan and Esther Mountains, two smaller mountains adjacent to Whiteface Mountain, on its way to an intersection with County Route 72 (CR 72), the last highway that NY 431 intersects. Just west of CR 72, NY 431 passes through a toll booth and becomes a toll road. The NY 431 designation continues along the highway to the Union Falls Overlook, a scenic view in elevation about one mile (1.6 km) into the scenic drive.
