Nestled amidst striking scenery and the deep gorge of the Slippery Rock Creek, in Lawrence County, Pennsylvania, a National Natural Landmark, McConnell's Mill State Park is a great place for an adventure. You can tour the restored rolling gristmill or the covered bridge. There is also scenic hiking, whitewater boating and two rock climbing and rappelling areas. Fishing is permitted anywhere along Slippery Rock Creek with the exception of the dam structures. There are two picnic areas adjacent to the parking area at the northern end of the gorge near the Old Mill.
