This run tours the Detweiler Run Natural Area, which is part of the greater Rothrock State Forest. Typical of central PA, you'll enjoy a hefty serving of rocks and guaranteed solitude since it is further into the forest than other local classics. Measuring nine miles total, you'll begin on the Mid-State Trail alongside a creek, with options to cut the run short once you reach Shingle Path. Those willing to push all nine miles will be rewarded with solitude, dense stands of pine and hemlock, and even some partial views in the wintertime.

Description

Noted by both Rothrock and this photographer, Detweiler Run Natural Area hosts stands of old-growth pine, hemlock, and birch, plus other hardwood species. The understory is shrouded by rhododendron, and the dense canopy offers cooler temperatures even into the summer. In fact, mature hemlock trees have been known to filter nearly 99% of light before it reaches the forest floor, making for a unique selection of stunning wildflowers and unique fungi found nearby.

One of the many things that makes this run great is a large campsite managed by Rothrock near the trailhead. One of only eight designated sites in the forest, you can contact the ranger station here to inquire about reserving the site for free. Parking is also available at the junction of Detweiler Road and Bear Meadows road, just be sure not to block any gates. Cell reception is limited, too, so be sure to download the route and directions prior to heading into the forest.
