Hammersley Wild Area, Natural preserve in Potter County, Pennsylvania.
Hammersley Wild Area is a protected area spread across Potter and Clinton counties in north-central Pennsylvania. It covers forested valleys, high plateaus, and stream corridors that flow through the interior without roads crossing them.
Heavy logging swept through the area during the late 1800s before timber operations shut down around 1900. The forest then grew back on its own over the following decades, producing the dense second-growth woodland that covers the land today.
The Susquehannock Trail System runs through the preserve for 10.78 miles, enabling visitors to connect with Pennsylvania's natural heritage.
There are no paved roads inside the area, so sturdy footwear and weather-appropriate layers are a must before setting out. The trails cross hilly terrain and can feel remote, so carrying a map and allowing extra time is a good idea.
Hammersley Wild Area is considered the largest roadless forest territory in Pennsylvania, shaped entirely by natural stream systems rather than any human infrastructure. This means it is possible to walk deep into the state and find complete silence, far from any traffic.
