McConnells Mill State Park, in Lawrence County, encompasses 2,546 acres of the spectacular Slippery Rock Creek Gorge, which is a National Natural Landmark.
Created by the draining of glacial lakes thousands of years ago, the gorge has steep sides while the valley floor is littered with huge boulders. Scenic overlooks and waterfalls are popular natural attractions.
Visitors can tour a historic gristmill and covered bridge built in the 1800s.

Seasons and Hours
The park is open every day of the year, sunrise to sunset. Day use areas close at dusk. The historic gristmill is open on a limited schedule.
Contact the Moraine State Park office for facility seasons and hours.
McConnell’s Mill sits adjacent to the park’s covered bridge and a beautiful dam and dates to 1868 (replacing an older mill that was destroyed in a fire). The mill was used as a gristmill and originally had a working waterwheel that powered it at one point.
When Thomas McConnell purchased the mill in 1875, he updated the machinery, making the mill one of the first in the country to use rolling mills. It would cease operations in the late 1920s.

Today, McConnell’s Mill is not only a beautiful focal point in the park but also features several interesting displays. The interior of the mill is open Wednesday to Sunday from Memorial Day Weekend through late September.
