The Cranberry Wilderness in southern West Virginia on the Monongahela National Forest is the largest USFS wilderness area in the eastern US. It is not near any major population center and has a very remote feel. According to Blue Ridge Outdoors, "The 47,815-acre Cranberry Wilderness located in Monongahela National Forest is not for the faint of heart. It’s called Wilderness for a reason; sundered only by unmarked trails, this seemingly endless temperate jungle of Appalachian hardwoods and red spruce is bestrewn with moss-covered rocks and dappled with wildflowers."
