Reddish Knob is located on the border between
Augusta County,
Virginia and
Pendleton County,
West Virginia, in the
George Washington National Forest. Reddish Knob stands within the
watershed of the
Potomac River, which drains into
Chesapeake Bay. The northwest side of Reddish Knob drains into Stony Run, thence into the
South Fork of the
South Branch of the Potomac River. To the south, Reddish Knob drains into the North Fork of the
Little River, thence into the
North River, the
South Fork of the
Shenandoah River, and into the Potomac River. To the east, Reddish Knob drains into the Briery Branch of the North River. From Reddish Knob, a scenic gravel road continues south along the ridge crest that forms the boundary between Virginia and West Virginia, passing Shenandoah Mountain Picnic Area in a couple of miles. Further south lies the
Ramsey's Draft Wilderness, which contains several stands of virgin hemlock. To the north, a rough road provides access to a number of ridge top balds that have great primitive campsites. Several developed recreation sites are nearby. Hone Quarry has a picnic area, campground with widely spaced sites, and a small lake. ==Recreation==
