Oaka Ridge Campground is deep at "end" of Prince William Forest (13 miles from forest entrance gate). 

There are three loops, front to back. Loop A are walkin only sites for RVs and tents. Loops B and C reservable. Loop B sites are for large families or groups. Loop C is more remote. Each loop has a bathroom building, Loop B is the only one with showers. There are no hookups in the campground, but drinking water is available near each bathhouse. Loop C had a working utility sink, the one in Loop B was closed. Not sure if A had one.

Free firewood is available behind the host's site.

We were in Loop C and could hear activity at Quantico. Lots of air noise too, from both airplanes and helicopters. We stayed 5 days, including a weekend. Saturday was the noisiest day with all the group camping activities. 

Sites varied greatly in size. Some seemed entirely too close, others spread apart. At times, sites seemed backwards - I kept saying they should reverse the one way direction so back in sites were easier. 

Ticks were really bad. We killed dozens and ended up taking at least one with us when we left.

The showers were hot, water pressure and shower heads good. Shower stalls offered more privacy than most, each having a locking door and small dressing area with a bench, and an adequate sized shower curtain, too.

Bathrooms could have been much cleaner. 

Only because of the ticks, we would not stay here again. We had Deep Woods Off, but seemed to do no good.
