The 1.5-mile Rock Furnace Trail is a scenic path in Roaring Run Recreation Area. The trail follows Roaring Run Creek from its confluence at the Kiski River to a small parking area off Brownstown Road. The steep, hilly trail makes for a scenic outing, taking in many small waterfalls along the creek. During spring, look for wildflowers in bloom, especially trillium that covers the stream valley hillsides.
The trail was built along a former gas well access road, and the highlight of the route is a 72-foot cable bridge built by volunteers to cross the creek. You'll also see the stonework remains of the Biddle Iron Furnace (a.k.a. the "Rock Furnace") near another landmark"Camel Rock," as it's locally known. The furnace operated during the era of canal transport, from 1825 to 1850.
At the southern end of the Rock Furnace Trail, by the canal, you can pick up the Roaring Run Rail Trail.
