South Prong Trail (TR 517)

Flatrock and Roaring Plains Wilderness

The Flatrock and Roaring Plains Wilderness is a vast wilderness within the Monongahela National Forest in the Allegheny Mountains of West Virginia. It includes Mount Porte Crayon, the sixth-highest point in the state—and only 93 feet lower than Spruce Knob.

Similar in characteristics with Dolly Sods but without the crowds, the Flatrock and Roaring Plains wilderness features the highest plateau in the eastern United States and the highest sphagnum bogs in the state. Along the tops of the mountains are rocky plains mixed with red spruce and mixed hardwood trees, along with blueberry heath, with an understory comprising of bogs, grasses, rhododendron, mountain laurel, and azaleas. It generally has fewer open meadows and windswept rock formations.

The Flatrock and Roaring Plains Wilderness features 15 miles of easy to strenuous trails. There are also extensive informal trails to Mt. Porte Crayon although the paths have become very difficult to follow because of vegetation regrowth.

  • The Flatrock Run (TR 519), Roaring Plains (TR 548), and Boars Nest (TR 518) trails make for a difficult 11.2-mile loop trail (when combined with walking along Forest Road 19 and County Roads 45/1 and 45/4). The route includes a greater change in elevation, at 2,200 feet, than any other trail in the national forest.
  • The South Prong Trail (TR 517) consists of 4.4-miles of an easy-to-moderate difficulty single-track path that begins and ends along Forest Road 19.
