Pennsylvania Scenic River · McConnells Mill State Park
Slippery Rock Creek drops through McConnells Mill State Park in one of the most dramatic sandstone gorges in Pennsylvania, delivering Class II–IV whitewater past historic grist mills and mossy boulder gardens. The gorge section is one of the premier intermediate whitewater runs in western PA, and the fall color through the gorge is some of the best in the state.
