Silver Thread Falls is a very easily accessible waterfall in the Delaware Water Gap on the Pennsylvania side. It is rather tall, but very narrow, and I think that makes it a very beautiful waterfall. Dingmans Falls is right on the same boardwalk/path, so you get double the waterfall fun.
1) As you’re driving along US-209 in Pennsylvania, you will enter the town of Dingman’s Ferry. Continue south on US-209 for a short distance.
2) There will be a sign for Dingman’s Falls, and you will turn right onto Johnny B. Mountain Road.
3) Head down Johnny B. Mountain Road to the parking lot for the falls.
4) Head down the handicapped accessible trail. Silver Thread Falls will be the first falls you encounter.
Note about Dingman’s Ferry: This is one of the few places where you can drive into New Jersey across the Delaware River. There are only a few bridges that allow access across the river, so if you’re looking for some waterfalls in New Jersey, this may be a good place to cross. (Buttermilk Falls and other New Jersey waterfalls in the Delaware Water Gap are most easily accessed by crossing this bridge.)
