McConnells Mill State Park is free and open to the public.

What to Expect:

McConnells Mill State Park is open from sunrise to sunset, year-round. It's a good park for active folks, with plenty of good hiking through scenic Slippery Rock Gorge, whitewater rafting down Slippery Rock Creek, and two climbing and rapelling areas. For the less adventurous, a crushed stone path winds down from the main parking area to the base of the gorge, the historic mill and the covered bridge. Switchbacks keep the path from being too steep, but don't forget it's uphill on the way back!

McConnell's Mill:

The gristmill for which McConnell's Mill State Park is named was one of the first rolling mills in the country, processing corn, oats, wheat and buckwheat for local customers. The historic gristmill is open on weekends and holidays from 11:00 a.m. to 5:00 p.m., from Memorial Day through Labor Day. Free, scheduled tours begin every hour.
