This trail follows Libby Creek, and is a rocky combination of old forest Rd, doubletrack, and some singletrack. It is well signed and marked with blue diamonds. For those faint of heart, it might best be ridden as a loop taking Barber Lake Rd uphill -> US 130 -> Green Rock Picnic Area and riding Barber Lake Trail back down to Barber Lake. Libby Creek Loop is an extra loop off of Barber Lake Trail near the Green Rock Picnic Area. The Corner Mountain trail system is also accessible from the Barber Lake area from Barber Lake road just above and below the lake and makes for a longer ride.
