Bull Run Regional Park, if that's the one you mean, is very pretty. Most of the campsites are spacious, wooded, and the bathhouses are clean. Lots of nice hiking trails, particularly the ones along Bull Run Creek. There is a waterpark - haven't been in it, but my grandchild loves it - also putt putt golf. Unfortunately, there is quite a bit of noise from a nearby rifle range, and, as the campground is close to Dulles Airport, occasional noise from planes overhead. The campround is about 15 minutes from the town of Centreville, VA, where there is shopping and a good selection of chain-type restaurants. Also, if you wish to see sights in DC, depending upon traffic, you can get there in about 40 minutes on Route 66 East.
We have stayed there many times over the years before we went fulltime. About 85 miles from our former house in Penna. About twice a year for ballgames, Fourth of July DC fireworks. Always worked great for us. Near a Metro station for inner DC travel.
We were there a few yrs ago, though we didn't consider it a deal breaker. Found the power box located no were near the water/sewer connections, had to do the extension cord thing. Also the sewer connection was to high not allowing for proper drainage. I've read some of the other sites have similiar issues also.

We have stayed there a few times and use it as a base when visiting relatives that live near there. The Metro station is a short distance although I-66 can get real crowded during certain times of the day. We enjoyed our stays and will most likely return when we visit our family again.
Over all it sounds like a pretty good place. I mean all campgrounds have pros and cons. Some are just horrible, I would love to purchase one and completely make it over. Anyway, thanks for the info. It makes me feel better knowing I am not stepping into a junk yard. Happy camping
