The summit is most easily accessed from Grayson Highlands State Park by following the Appalachian Trail southbound for 3.5 miles (5.6 km) to a blue-blazed trail leading to the summit, which is covered by trees and marked with four National Geodetic Surveytriangulation station disks; a standard station disk marked with an equilateral triangle and three standard reference disks marked with arrows pointing towards the station disk. One reference disk has been obscured by dense overgrowth. Because the Appalachian Trail passes within a half mile of the summit, the area is especially popular with hikers.
The Mount Rogers area contains a unique record of the geohistory of Virginia. There is evidence from the rocks that volcanoes were part of the landscape. Roughly 750 million years ago, rift-related (divergent) volcanoes erupted along the axis of what later became the Appalachians, and one remnant of that volcanic zone, with its volcanic rocks, still can be seen at Mount Rogers. Massive rhyolitelava flows erupted at the mountain during the Precambrian rifting event. Mount Rogers is also the only place in Virginia that preserves evidence of ancient Proterozoicglaciation.
