Lewis & Clark Mainline

  • TRAIL DISTANCE

    13.7 Miles

  • ELEVATION GAIN

    323 ft.

  • Maximum elevation

    619 ft.

  • Difficulty

    Easy

Trail Description

The route follows the Lewis and Clark River crossing 5 bridges and passing by a small dam and fish ladder. The route was originally a logging railroad that was converted to a haul road as trucks replaced steam trains after World War I. The most outstanding remnant of its railroading past is the single-lane steel Bridge spanning the spectacular South Fork Gorge 2.4 miles from the entry gate. Other remnants include pilings from a small trestle visible on the west side of the route at the first bridge 1.7 miles from the gate and remains of the old road bed which can be seen at various points. Otherwise, the ride offers many great views of the river and forest and provides access to some great fishing spots along the route. The ride is mostly level with some gentle climbing. Since the route follows the same road in and out, it can also be ridden as a shorter ride.

The Ride

Ride past Entry Gate number 71 on Lewis and Clark Road. If the gate is closed, go around the left gate post and ride straight ahead on the paved road past an office and shop area at 3/4 miles on the right. The road surface changes to gravel beyond the office. Continue through gate 75
just past the buildings. If the gate is closed go around the gate on the right side.
  • At 1.7 miles cross a small bridge. Pilings from an old trestle can be seen off to the right from the north end of the bridge.
  • At 2.4 miles cross a single-lane steel bridge spanning the South Fork Gorge.
  • At 2.9 miles cross a single-lane bridge over the Lewis and Clark River.
  • At 3.2 miles pass a dam and fish ladder on the right.
  • At 4.9 miles cross a single-lane bridge over the Lewis and Clark River.
  • At 6.8 miles cross a single-lane bridge over the Lewis and Clark River.
  • At 6.9 miles reach the ride turn-around. The original railroad grade is visible on the other side of the roadside berm at the turn-around point. At this point the road makes a curve to the left and begins a steep climb.

For more information on the Lewis and Clark Mainline beyond this point, refer to Seaside Visitor Bureau Ride Route #1A, Upper Lewis and Clark

Mainline. Turn around at this point and follow the same route 6.9 miles back to the entry gate and Lewis and Clark Road.

The route makes three more steep climbs before finally achieving the summit. The overall climb to the summit is a moderate 5% grade for 2.7 miles but it is done in a series steep climbs with moderate stretches in between. Continuing on the Spur 2 Road, the route descends to the Lewis and Clark Mainline at an average grade of -11% for one mile. The ride then follows the Lewis and Clark Mainline back to Entry Gate 71 crossing four bridges and passing a small dam and fish ladder and Gate 75 on the way.

The Ride

Go through Entry Gate number 71 on Lewis and Clark Road and ride straight ahead on the paved road past an office and shop area at 3/4 miles on the right. Continue through Gate 75 just past the buildings. If the gate is closed go around the gate on the right side. Stay on the well-traveled road for 2.4 miles crossing two one-lane bridges.

  • At 2.4 miles and just past the steel South Fork Bridge, take the South Fork Road on the far right.
  • At 3.6 miles, take the left fork onto the Spur 2 Road (unsigned) and begin a steep climb.
  • At 4.2 miles, ride past a corral on the left side. No one seems to know for sure what purpose this corral serves but judging by the 8 foot tall fences, it probably has something to do with deer or elk.
  • At 5.0 miles, keep left to continue on the Spur 2 Road (unsigned).
  • At 6.0 miles, reach the summit and begin a steep descent.
  • At 7.1 miles, ride through Gate 62 and turn left onto the Lewis and Clark Mainline.
  • Follow the Lewis and Clark Mainline for 6.3 miles back to the entry gate, crossing four one-lane bridges, passing by the Warrenton Water Supply Dam and passing through Gate 75.

Technical

Ride Time: 1.5 hours. Several climbs with grades in excess of 15%. Steep descent. The final climb to the top is very steep on loose gravel. Traction can be a problem on this section. The steep descent to the Lewis and Clark Mainline has a section with deep ruts and loose rock that requires caution. Expect weekday truck traffic on the Lewis and Clark Mainline.
