Primitive camping in virginia , must have campfires allowed and preferably 3+ mile hike to a campsite. Military moral camping trip i am trying to save

My shop has 11 of us all ready to go camp at false cape state park and hike the 8.3 miles to our campsite and just have a night or two in silence. We planned extensively ...until we realized campfires were banned at false cape. With it being late November for our trip and also kinda killing the whole camping vibe without a fire I unfortunately have to rule out our choice of false cape state park. Are there any primitive camp sites, minimal ammenties, secluded, fires allowed and 3+ miles hike out within an hour ish of langley afb? Please and thanks! I see cavalier wma but its a bit of a small area so not much of a hike
