One of the nicest campgrounds in the DC area. Sites are well maintained, as are the restroom and shower facilities, and the sites are fairly large and well separated. Loop C is best for privacy and tent camping, Loop B for groups, and Loop A for RVs and campers (no electric hookups). Campground is near several trails and has easy access to the bike paths. Note that you have to pay for park entrance separately from the camping reservation. It’s a bit of a drive to get to the campground from the park entrance, so work that into your schedule.
