We tent camped there two years ago,  at one of their premium sights ( totally worth the extra $) I grew up camping and had never been at a campground that was this clean. I mean the bathrooms were pristine at all times. ( I actually felt bad when a moth flew in with me the one night because there weren't any bugs in there, EVER). They have 2 pools, a hot tub, $1.00 putt putt ( great coarse, with all proceeds going to a childrens hospital) splash pad, laundry,  game room, cafe, playgrounds....It is located fairly close to DC and the zoo. The only downside, is that it's near highways, so at times, you can hear traffic and you are forced to buy firewood from the campground and it could get pricey because there arent any local sellers like most places We had an amazing, relaxing stay and I would highly recommend staying there if you're visiting DC or just passing through.
