This trail actually starts at Green Rock Picnic Ground at milepost 34 on Hwy 130. It's mostly downhill with some great natural features that are good for catching air while going fast. Let it rip! Some rocky and moderately technical sections require skill.
It starts on the rim of Libby Creek Canyon and then drops and follows the creek to Barber Lake and Barber Lake Road, which is the old highway and is paved.
Before simply heading down the pavement to the Centennial Visitor Center, consider jumping on one of several entry points to the Corner Mountain Trail
system. Head left or right on Barber Lake Road and look for brown USFS Trail signs and some of the classic blue diamonds marking them as Nordic trails.
