From the trailhead, head into the woods on the red-blazed Coppermines Trail. Just past the trailhead, you’ll come to a fork. Bear left and follow a branch trail that parallels a cascading stream and leads in 750 feet to the sealed-off entrance of the lower mine – a relic of Dutch explorations for copper in the 1600s.
Retrace your steps to the fork and bear right, soon passing the ruins...
the red-blazed Coppermines Trail. In another 400 feet, the barricaded entrance to the upper mine is to the right of the trail. The trail now narrows to a footpath and soon levels off, with a cascading brook in a deep ravine on the left.
In another mile, you'll come to a series of open grassy areas, with panoramic east-facing views. Lower Yards Creek Reservoir is visible directly below, and the northern end of Mt. Tammany may be seen to the south. The A.T. continues south along the ridge, with more views to the left of the trail.
After enjoying the vista, retrace your steps back to the first junction with the Kaiser Trail (now on your left), and follow this blue-blazed trail downhill. For much of the way, the trail is a grassy woods road, but in places it has narrowed to a rocky footpath. After about a mile of relatively easy walking, you'll come to a trail junction at a huge log, with a sign for a spur trail to the Coppermines Trail. Turn right and follow this short red/blue-blazed trail. After crossing two brooks, you’ll reach a junction with the red-blazed Coppermines Trail. Make a left here, retracing your steps as you descend through the gorge, and follow the red blazes back to the trailhead, where the hike began.
