I went to Dingman's Campground, which is about 10 minutes away from the famous Dingman's Bridge. The bridge is old, wooden decked structure, and the one dollar toll is collected by a man standing in the middle of the road with a plastic bucket on the Pennsylvania side of the bridge. A trailer adds an additional one dollar to the toll.
The campground is very nice, with large sites, and patrolled by park rangers as well as the camp staff. Of the more than 100 sites, there were probably only about 30 filled, so I managed to find a nice quiet location, with no neighbors within six sites or so. The campground also offers "river front" sites, but a walk to those sites discouraged me from paying the extra five dollars for the privilege.
For a National Park the rates were rather steep at thirty two dollars a nite. The price for firewood was very fair, twelve bucks got you a real nice sized stack. After two nights of a fire, I still had some left over.
I spent an afternoon driving about, and visited a couple of the falls that the area is famous for, as well as spent some time down by the river. Canooing is very poplular, and about every 30 minutes, another group of eight canoos would land.
