In typical riverside trail fashion, the ride becomes more challenging as it progresses upstream, with upper Quartz Cr Tr5 proving unrideable/dangerous for many people.

Lewis River Tr31 offers some brief examples of steep hillside terrain but is merely challenging and not usually life threatening.

The lower section practically defines the meaning of flow, with fast, twisty, mossy trail that goes on and on.

Since FR90 parallels Lewis River Tr31 and provides access at both ends of the trail, the ride could be done as a shuttle.

The terrain is flat enough and offers enough variety to justify riding OAB.

FR90 crosses Lewis River Tr31 at 9.7mi and 14mi (upper TH).

Those seeking a more aggressive ride might consider starting at the 9.7mi TH or the Lower Falls Recreation Area, and riding Lewis River Tr31 and then Quartz Cr Tr5 to the Snagtooth Tr4 intersection.


A CCW lollipop loop can be created by adding Wright Meadow Tr80, Bluff Tr24 and Cussed Hollow Tr19. This increases the climbing without significantly increasing the distance.

If camping in the area or looking for more local terrain, check out Spencer Butte Tr30 and Wildcat Tr25, accessible from the Spencer Butte or Cussed Hollow TH on FR93.

Popular with day-hikers, expect to share the first few miles of trail with families and their pets.

The upper trailhead ends at the Lewis River Horse Camp, so expect to see the occasional horse wandering by on the trail.

Be sure to give the horses plenty of room (get completely off the trail) and speak gently as they are passing, especially if on steep hillside terrain where they might be easily spooked.

Directions: NW Forest Pass required right at the TH. See Map. See the Topo Map for the other trailheads. View Larger Map. No Map?.

  • TH: From the FR9039 parking area, ride across the bridge and join the trail on the right side of the road.
  • 5.4mi: Having passed the Bolt Camp Shelter and the fastest section of the trail, go past the intersection with Speed Tr31E (which accesses FR90 but requires fording the river and may not be well maintained due to lack of use). Terrain becomes more intense, with short hillside climbs and detours due to washouts.
  • 7.8mi: The end of the steepest climbing, culminating in a 1mi section that most will have to hike.
  • 9.2mi: Some fast riding through dense forest to the Bluff Tr24 TH, then cross FR90 at 9.7mi. Pass the Lower Falls Recreation Area at 10.9mi.
  • 12mi: After some climbing, reach the Wright Meadows Tr80/Cussed Hollow Tr19 TH and some local Middle Falls trails, then resume climbing to the upper TH, at FR90. Turn around and head back, or continue on to Quartz Creek Tr5.
