No, "Monster Rock" is not paying homage to heavy metal rock-n-roll bands. However, the rock is very appropriately named, as it rises above the Monster Rock Trail portion of the Walker Mountain Trail in Virginia.
Ridgeline Near Monster Rock
Once a part of the original Appalachian Trail, Monster Rock used to be a semi-popular destination for hikers. However, the Walker Mountain section of the Appalachian Trail was bypassed starting in 1977, due to lack of water sources along the Walker Mountain ridgeline. However, the Monster Rock Trail/ Walker Mountain Trail can still be followed to the redirection point at Crawfish Valley. Since 1977, the Appalachian Trail was instead redirected through Rich Valley to Garden Mountain and along the southern edge of Burke's Garden, where multiple water sources are available during that stretch of the trail. As a result, Monster Rock lost popularity due to fewer visitors.
The trail starts just west of the Big Walker Mountain Lookout parking area. The trail starts at an elevation of 3466', rising over 200' elevation in less than 0.5 miles to Monster Rock. The trail follows the ridgetop, occasionally steep and always forested. Shortly before reaching Monster Rock, there is a scenic overlook (indicated by a sign) that has a gorgeous view northwest towards West Virginia.
The tree-cover is dominated by oaks and maples, very typical of an Appalachian ridge. Rhododendrons and mountain laurels bloom along the ridgetop, including at Monster Rock itself. Deer are frequently found within the forest, as well as songbirds and hawks. Occasionally turkey vultures can be seen from the scenic overlook.
