Take New York State Route 17 to Hancock, NY. Cross the bridge into Pennsylvania. (There are two bridges in town, the other crosses the Delaware River but stays in New York - becomes N.Y. Route 97 - that's the wrong bridge!).
After crossing the bridge into Pennsylvania, the road forks at the big 'Welcome to Pennsylvania' sign. The left fork is PA Route 191, the other is a short local road. Stay to the right (on the local road) at the big sign.
Go straight about one block, until that short local road ends, then make a right. You will pass an industrial yard to your right with a chain link fence. The trail is hidden up on top of the incline, in the woods, to your left.
Explore around, there are several steep dirt paths and roads up to the trail, one is big enough for a 4WD vehicle. Find the trail. Then go back and find safe parking.
Once on the trail, you will be surrounded by overhanging trees and beautiful, secluded forest. Further along, there are impressive cliffs 20 to 30 feet high to your right. The roadway is smooth, with occasional rocks and lumps of coal. The color of the roadway (coal dirt gray) is the only unattractive feature of the trail. Otherwise it was a lovely walk.
The only problem is the (infrequent) sharing of the trail with motorized vehicles. In four hours on the trail on Memorial Day Weekend 2010, we passed by one family on ATVs, and one 4WD truck.
Bring enough water, do not expect your dog to drink from streams, as there are none that are convenient from the trail.
The trail is very nice to the Starlight Station (now a town shed), more to come as we explore.
