Wilderness Landscape & Natural Heritage
Nyes Run Natural Area is located within Loyalsock State Forest in north-central Pennsylvania, encompassing a rugged and unspoiled tract of mixed hardwood and hemlock forest along the upper reaches of Nyes Run and its tributaries. This 258-acre parcel preserves one of the finest examples of old-growth eastern hemlock and white pine ecosystems in the region and is especially notable for its dense canopy and mature forest structure. The area features steep slopes, rocky ravines, and clear cold-water streams that provide critical habitat for native wildlife including brook trout and a diversity of bird species. The natural area was designated to protect these ecologically significant forests and water resources from logging and development, maintaining a representative sample of pre-settlement Pennsylvania woodland. Visitors are drawn to Nyes Run for peaceful hiking and immersive nature study. The area does not have developed facilities or marked trails; accessing it requires navigating rugged forest terrain and small footpaths. Historically, the surrounding Loyalsock State Forest was heavily logged in the 19th and early 20th centuries, making the preservation of Nyes Run’s old-growth stands especially significant. The natural area offers a glimpse into the state’s ecological past and remains a refuge for conservation-minded hikers and naturalists seeking solitude. Bird-watchers appreciate the presence of forest interior species, and anglers find small trout streams in the vicinity. With minimal human disturbance, Nyes Run Natural Area is an ideal destination for backcountry exploration and wild forest experiences within Pennsylvania’s broader system of state forest lands.
