We arrived here on June 24 for 4 nights to visit Washington D C. There are not many campgrounds in the area and the few here are pricey. This park is a very large county park, located in Reston, Va.; with a great water park for the kids and adults alike with water falls, water slides, and a man made river where you can raft on provided innertube's. There is also a lake on the property where you can rent paddle boats; or for a fee of $5 launch your own kayak. There was no swimming in the lake, but I noticed several people fishing. Our site was level and quite nice with trimmed grass surrounding the campground. Campsites here are either primitive or electric only. We had 50 amp service and there was also a dump station with fresh water provided at a central location by the bath house. There was also 20 miles of hiking trails throughout the park. We were located about 2 miles from the Washington Metro Train Station and we used to commute about 20 miles into Washington DC on two separate days. Our campsite was $40 per night after a $5 discount for seniors. We had good cell service, TV over the air and I was able to get dish satellite reception for the first time on this trip. Plenty of shopping nearby and the catholic church was located just outside the park. I rate this park P****.
