In order to access C Trail, you'll have to ride portions of the DRLA Trail. Combine this trail with the Henry Lake Trail and you'll add another 6 miles to your ride. Want more? Add the RCW Trail!
Start this trail at the end of the RCW Trail. Keep left and ride the easy singletrack through the trees. About 1/2 mile in you'll pass through an area where there has been an old burn. The trees all survived, but it really cleared out the underbrush. At mile 1.0 you'll cross the junction with the Henry Lake Connector Trail. Stay left at this junction. At mile 1.2 you hit the end of the C Trail and will come to a confusing set of junctions. At the first junction there is a sign, but it is buried in the bushes. Left takes you to the Pipeline Trail and right takes you to a second junction where the Trail of Woe crosses FR 220. Either way gets you back to the DLRA Trail, but the Trail of Woe is quicker.
Like the other trails in this area, this trail is easy to follow and made up of nice, flowy singletrack. There are a few junctions along the way, but they are well signed and easy to follow.
