​Kinzua Sky Walk

Keating, Pennsylvania

The Kinzua Sky Walk was once a railroad bridge, used to transport coal, oil, and lumber across Pennsylvania’s Kinzua Gorge. When a powerful tornado destroyed the bridge in 2003, it was rebuilt as a pedestrian walkway, with glass panels installed so visitors can look down into the gorge. You also get a nice, long stroll over the wilderness, as the Sky Walk extends for 624 feet.
