Johnson Run Natural Area

Johnson Run Natural Area is a protected forest area in Cameron County featuring steep valleys and boulder-studded plateaus separated by flowing streams. The landscape displays varied terrain where water has carved deep channels through the surrounding woodland.

The natural area preserves stands of old-growth forest containing Eastern Hemlock and Eastern White Pine trees that have reached substantial size. These ancient woodlands represent forest conditions that existed before intensive human land use.

This protected landscape maintains ecological systems while offering opportunities for research, education, and observation of Pennsylvania's native wildlife.

The natural area welcomes visitors year-round and allows dogs to accompany their owners on the trails. Prepare for uneven ground and variable conditions depending on the season and recent weather.

The deep valleys were carved by water erosion over long periods, revealing geological layers that show how streams shaped the landscape. This natural process makes the site valuable for understanding regional geology.
