Slippery Rock Creek


Slippery Rock Creek is a small stream in Western Pennsylvania, a tributary of Connoquenessing Creek. From its source in Hilliards in Butler County, it flows through McConnells Mill State Park before flowing into the Connoquenessing in Ellwood City. Then, the Connoquenessing flows into the Beaver River just three miles south from the mouth of Slippery Rock.
Slippery Rock Creek is a favorite for whitewater kayakers and canoeists from Pittsburgh and Ohio. With Class-II and -III rapids and engaging beauty, it attracts regular paddlers from novice to advanced level. Slippery Rock Creek, however, can be very dangerous. The rocks are indeed deceptively slippery, and throughout the year, there are numerous reports of drowning incidents, mostly near the McConnells Mill State Park.
