Kristen, I assume you're talking about the C&O trail. The trail is dotted with free camping spots, most of which include a potable water cistern/pump and a portajohn. There are also some pay campgrounds (one example is along the trail near Brunswick, it has hot showers). If you're talking about the GAP trail, that is different. There are no campsites on the trail, but there are a few pay campgrounds, but they're few and far between.
