Kinzua Bridge State Park
The 329-acre Kinzua Bridge State Park is in McKean County and features remnants of the 2,053-foot railroad bridge (viaduct) that was a National Engineering Landmark. A tornado has knocked down much of the bridge.
The bridge overlook gives great views of the viaduct and the Kinzua Creek Valley. The accessible overlook is great for viewing fall foliage and the Kinzua Creek Valley. Peak viewing times are the first two weeks of October.
