Charcoal Hearth Trail
2.7 miles, most difficult
This is the longest and most rugged trail in the park.
With its trailhead at the falls on Thaddeus Stevens Historic Trail, Charcoal Hearth Trail climbs steeply for 10-15 minutes to Graeffenburg Mountain before leveling off, then descends gradually, ending by a quiet stream near the Furnace Dam and pond. On the descent, watch for four historic charcoal hearths (noted on the map) and an old wagon road.
Keep a watchful eye out for squirrels, chipmunks, birds, and deer.
