About McConnells Mill

McConnells Mill State Park is western Pennsylvania's main climbing area — a well-cemented Pennsylvanian sandstone gorge (Pottsville / Homewood Formation family) along Slippery Rock Creek, an hour north of Pittsburgh. The Slippery Rock Creek Gorge runs roughly north–south so cliffs face both east and west; treat the aspect as various. Sub-areas are Breakneck Bridge, Rim Road Climbing Area, North Country Trail Area, The Projects, and McConnells Mills Ice & Mixed (winter). The heavily forested gorge holds moisture — expect long drying after wet spells and vicious mosquitos June–August. October through April is the pleasant season with prime friction. Rock climbing or rappelling is prohibited on rocks along any road inside the park. PA DCNR — free day-use, no permits.
