Trail Description

The route is an extension of Seaside Visitor Bureau Mountain Bike Route 1, The Lewis and Clark Mainline. Beginning at the turn-around point for Route 1, the route continues to follow the Lewis and Clark Mainline to its intersection with Saddle Mountain Road. Beyond the turn-around point for Route 1, the original road was washed out in a flood forcing a 2-mile detour higher up the side of the canyon. This portion of the route includes a moderately steep climb and descent. The final 2.5 miles resumes a gentle climb to Saddle Mountain Road. The combined routes offer two options to riders. They can be done as a 22-mile round-trip loop beginning and ending at the Entry Gate 71 at Lewis and Clark Road. They can also be done as an 11-mile one-way ride by arranging for a pick up at Lewis and Clark Mainline Entry Gate 57 at Saddle Mountain Road which is accessible by car. The route provides some pretty views of the Coast Range Mountains including the north side of Humbug Mountain. There is a pleasant view of the Lewis and Clark River from a small bridge just off of the Lewis and Clark Mainline at Bridge 11 Road.
