Short on length but long on natural beauty, this is one of the gems of the Trans Allegheny Trail system! It’s also two trails in one. The Roaring Run Trail flows for five miles up the Kiskiminetas River, while the Rock Furnace spur follows Roaring Run for 1.5 miles upstream. Both trails are naturally beautiful with extensive stands of wildflowers, stately hardwoods, and water cascades. Both also are historical: Roaring Run Trail sits along what once was the Main Line Canal and passes several canal traces, while Rock Furnace Trail features a wooden suspension bridge and the stone ruins of an iron furnace from which it got its name. Roaring Run Trail begins at a trailhead at the end of Canal Road and extends for five miles alongside the Kiskiminetas River. The initial three miles have a crushed limestone surface and are fairly level, while the final two miles involve some steep climbs. The final mile to the Edmon trailhead is tar-and-chip. The Rock Furnace spur features a moderate grade over its 1.5 miles and has a tar-and-chip trail surface. More than 15 miles of mountain biking and hiking trails are located on the hillside above the Roaring Run Trail.
