Brown Mountain and Rockytop Loop

Brown Mountain and Rockytop Loop is an 18.6-mile backpacking circuit that starts and ends at Brown Mountain Overlook on Skyline Drive, milepost 77. It links Brown Mountain Trail, Big Run Portal, Rockytop Trail, Big Run Loop, and Rocky Mountain Run, dropping into the Big Run wilderness valley before climbing back to the overlook. The park's itinerary sets it up as a three-day trip for experienced hikers. Its written distance is 18.6 miles while the assembled trail line measures 17.75, so treat the figure as approximate and plan for roughly 18 miles.

The first day follows Brown Mountain Trail toward Big Run Portal and a backcountry campsite. On day two, cross the bridge to Rockytop, follow its long ridge section, then take Big Run Loop and continue along Big Run Portal to camp again. The final day stays on Big Run Portal to Rocky Mountain Run, then follows that trail and the short Brown Mountain return to the overlook. The suggested daily ranges are about 5.5 miles, 8–10 miles, and 3.4–5.4 miles; the location of the second campsite shifts distance between the last two days. Expect about 16 hours of hiking across the itinerary, before camping and long breaks.

Rockytop is the high, rugged middle stretch. A route account describes talus slopes and rough, brushy footing on the ridge, with westward openings toward Massanutten Mountain and Lewis Peak. The last roughly two miles descend about 1,500 feet toward Big Run, so save energy for a sustained drop into the valley rather than assuming the ridge is a quick out-and-back. A sampled elevation profile ranges from roughly 1,300 feet in the valley to about 2,800 feet near the overlook and suggests around 3,100 feet of cumulative climbing.

Big Run is the route's central valley and its main camping and fishing setting. Big Run Portal crosses several streams. When water is high, especially in spring or after heavy rain, crossings can reach knee or waist depth. The route can be harder to follow where it crosses the water; pause to find the marked continuation before stepping onto a midstream island or leaving the bank. Do not force a crossing that is unsafe.

Use Brown Mountain Overlook at milepost 77 as the trailhead. Overnight camping requires a Shenandoah backcountry permit, arranged before leaving; camping is dispersed, so choose a legal site away from streams, trails, roads, and other restrictions. The route description lists no food service or potable-water stop, so carry meals and a way to make natural water safe. Campfires are allowed only at park-built fireplaces, and none is identified on this route. Dogs are allowed on these trails on a physical leash no longer than six feet.
