Get a map and find Sandy Hook. Once inside the park, drive to area G which gives you the closest access to Gunnison Beach. Not all the beaches at Sandy Hook are nude. You must use the designated area at Gunnison. If that lot is full, you must go to an overflow lot and walk a greater distance. Take the boardwalk to the beach and you're there!
