A short loop, but with big, steep climbs. Many runners do three or more repeats of this loop as a significant hill workout. Simple logistics are another hallmark of this run, since aid is available at your car betwwen loops and the trailhead is only 65 miles west of the Beltway.
From the parking area on Route 211 take the Buck Hollow Trail 0.2 miles to the intersection with the Buck Ridge Trail. Take a left onto the blue-blazed Buck Ridge Trail and begin the steep ascent. At the top of the ridge, make a right onto the yellow-blazed Hazel Mountain Trail (mile 3.0) and in 0.5 miles come to the Hazel Mountain parking area on Skyline Drive. From there, take the blue-blazed Buck Hollow Trail back to your car.
