From the Lewisburg, PA area, follow Route 45 West through Mifflinburg, then over the mountain to Woodward. Turn left at the Woodward Inn. Woodward Cave is then 2 miles.
Do not follow any GPS instructions that follow unpaved mountain roads. The mountains around Woodward are covered with dirt roads that sometimes show up on GPS mapping but you want to stay on paved highways.

Map Quest just doesn't know where we are. Ignore anything that says 2107 State Route 45.
