McConnell's Mill State Park

Breakneck Falls in McConnell's Mill State Park

McConnell’s Mill State Park is one of the most highly regarded and scenic parks in Western Pennsylvania and is located less than 35 minutes from the OH-PA border. The park preserves the Slippery Rock Gorge and Hell’s Hollow, a tributary stream that flows through a narrow gorge and over a beautiful waterfall. Perhaps the most scenic spot in the park is Cleland Rock, a large rock outcropping the sits atop the rim of the gorge and gives you a great view of the valley below. Part of the famous North Country Trail passes through the park, which will span 8 states and 5200 miles upon its eventual completion. At the center of the park is McConnell’s Mill: the historic mill for which the park was named.
