River Road, as it exits from 95, takes you up to a traffic light in Washington's Crossing; there is a couple gas stations caddy-corner from each other and a bank/supermarket on the other. You take a right at that light onto Washington's Crossing Road (natch
), also known as Rt. 523, down to a 4-way stop sign; make a left at that stop sign, go about 150 yards and the park entrance is on your left. Has a big flagpole sitting in a stone base. Can't miss it.
