The Rock Furnace Trail is a moderate 3-mile out-and-back spur trail that runs through the scenic Roaring Run Reservation Area in Apollo, PA.

The trail leads from Brownstown Rd down to the Kiski River and follows Roaring Run Creek the entire length of the trail. There are numerous small waterfalls along the creek and 1-mile in, you'll cross a suspension bridge.

You'll also find the stonework remains of Briddle Iron Furnace (aka Rock Furnace) which operated from 1825 to 1850. "Camel Rock" is also directly on the trail, jutting out from the side of the path with an overhang cave underneath.

Dogs and biking are both allowed on this trail.
