McConnell's Mill State Park

Occupying a massive 2546-acre plot inside of the Slippery Rock Creek Gorge, McConnell's Mill State Park contained not one but two National Natural Landmarks. The scenery contained within McConnell's Mill State Park shouldn't be missed, as it's counted among some of the most breathtaking landscapes in Pennsylvania state. 

Hiking is a favorite past time here, with over 11 miles of trails available forgets to jump on and explore. Due to these trails getting difficult to navigate depending on the season, all of them are blazed to keep hikers on track while they travel through bits of rugged terrain. Guests who are looking for a casual stroll will enjoy the ironically named Hells Hollow Trail. 

It's only about a half a mile long and offers some spectacular views of the Hells Hollow Falls. Guests should take care when approaching the falls, as the ground surround them can get quite slippery. If you're someone looking for a real challenge, the Alpha Pass Trail offers steep grades and several preserved structures from the 1800s including the Old Mill. 

Make sure to grab a trail guide at the park's central offices before setting out. Park officals suggest a fully charged cellphone, sturdy hiking boots, and fresh water if guests are going to attempt any of the longer hillside trails. If you'd like to bring your doggo on a hike make sure you have a leash to keep them on, as unrestrained dogs aren't allowed in Pennsylvania State Parks. 

Free climbers and rappellers are both welcome in McConnell's Mill State Park, with two different areas catering to both sports. For advanced climbers, there's Breakneck Bridge, located near the Old Mill. The Rim Road climbing area is more for intermediate climbers and can be found at the southern edge of the park. Canines can accompany guests to these spots but have to stay restrained outside when guests enter the climbing offices.
