Approximately 6-mile roundtrip hike from VA-80 in Hayter's Gap to the Great Channels of Virginia on Middle Knob. Incredibly scenic hike along Clinch Mountain from Hayter's Gap to Middle Knob along the 14-mile Brumley Mountain Trail, one of the East's newest long (10 miles+) hiking trails. Although the Brumley Mountain Trail runs all the way from Hayter's Gap to Hidden Valley Lake off of US-19 in Moccasin Gap, this guide features the trail's most heavily used, easternmost 3 miles that travel to the Great Channels of Virginia.
