McConnells Mill State Park

McConnells Mill State Park encompasses the spectacular Slippery Rock Creek Gorge. Created by the draining of glacial lakes thousands of years ago, the gorge has steeps sides and the valley floor is littered with huge boulders.

The operational gristmill built in the 1800s, shows how waterpower ground grains into flour in the days before modern electricity-powered mills. It is open for tours.

The park provides an abundance of activities from casual picnicking and fly fishing to climbing and rappelling for the experienced. Whitewater boating or rafting is a popular sport, for those who have plenty of training, as the rapids in the park are powerful and turbulent.

The trail of geology educates geology enthusiasts, pointing out glacial activity and rock erosion patterns that naturally formed the scenic gorge.

McConnells Mill Heritage Festival is held on the last full weekend in September, hosting corn grinding demonstrations and a Civil War encampment.
