Join us as we head up to explore the Blue Ridge Tunnel. This 4.5-mile hike features a former rail tunnel that runs underneath Rockfish Gap, connecting Augusta County and Nelson County. Be sure to bring your headlamp or flashlight, as the tunnel does not contain any lighting for its nearly mile-long path underground. If you do not have a headlamp or flashlight, one will be available for use. Minors must be accompanied by an adult.
