Hiking

The Kildoo Trail offers a delightful journey through McConnells Mill State Park, tracing the lively Slippery Rock Creek. You'll find yourself amidst green woods, passing numerous small waterfalls, and eventually reaching the impressive Kildoo Falls, where you can even walk behind the water. The terrain varies from smooth to rocky and root-filled, with gentle ups and downs, making this 3.8-mile (6.1 km) hike a scenic adventure.

This easy route, with only 286 feet (87 metres) of elevation gain, typically takes about 1 hour and 39 minutes to complete. It's a great option for families and is dog-friendly, provided your furry friend stays on a leash. Parking is available at the state park, and while the trail is generally easy, good hiking boots are recommended due to the varied and sometimes uneven surfaces.

Beyond the natural beauty, the Kildoo Trail is rich in history, connecting you to the historic McConnells Mill and a picturesque covered bridge. You'll also find unique opportunities to access large boulders within the creek's rapids, offering different viewpoints. This trail is a fantastic way to experience the natural and historical landmarks of the region, especially during spring wildflowers or vibrant fall foliage.

McConnells Mill and Covered Bridge

Highlight • Historical Site

Daniel Kennedy opened a gristmill on Slippery Rock Creek in 1852. The mill was rebuilt after a fire in 1868. McConnell acquired the mill in 1875, replacing the waterwheel with turbines and grindstones with rolling mills, making it one of the first of its kind in the country. The mill ground various grains until it closed in 1928. The ownership passed to the Commonwealth of Pennsylvania in 1957, leading to the formal dedication of McConnells Mill State Park. Today is the mill. Today, interpretive tours of the historic mill are available at 1:00 p.m. and 2:00 p.m. in the summer. For interpretive tours for groups, call the Moraine Park office at 724-368-8811.
