Come here yearly in December for Devil Dog Ultras. Never been disappointed. Haven't stayed in any of the bunk houses, but the bathrooms are clean and stocked, plus there's a shower.
Cabin Camp 5 is awesome! We make an annual trek here on Thanksgiving to spend the day with friends and family. The main hall will is rustic but well furnished and maintained. The kitchen meets all of our needs and has all of the equipment you would expect. There's also a gigantic stone fireplace. And since the camp is inside Prince William Forrest Park there's plenty to do outside the cabin.
Nice bit of a get away in the northern Virginia area. You would be surprised on how away you feel while being close. There is extremely limited cell coverage however.
