The Oregon Timber Trail

The Oregon Timber Trail runs 670 miles from the Idaho border near Hells Canyon to the California border in the Cascades. This is a dedicated mountain bike route, not a road tour. Expect sustained singletrack, technical root sections, volcanic pumice fields that eat your tires, and some of the most remote riding in the continental United States.

Overview

The OTT was developed by the Oregon Timber Trail Alliance as a mountain bike-specific long route that links Oregon's working forests, wilderness areas, and national forests. Unlike the more famous Oregon Backcountry Discovery Route (which is primarily for motos and Jeeps), the OTT is built for fat-tire bikes capable of handling true singletrack. Most bikepackers ride it on a hardtail or a long-travel gravel bike with 2.2-inch tires minimum.

The Route

The route begins at Hells Canyon on the Snake River — one of the deepest river gorges in North America — and climbs immediately into the Wallowa Mountains. The Wallowas are the northeastern section's defining feature: exposed granite ridgelines, high alpine meadows, and views that extend into Idaho. This section is technically demanding and often the most physically challenging per mile despite not being the highest terrain on the route.

Heading southwest, the trail passes through the Blue Mountains and the Ochoco National Forest before hitting the volcanic landscape of central Oregon. This is where the OTT becomes unlike anything else in the lower 48. The Newberry National Volcanic Monument, Deschutes National Forest, and surrounding lava fields create a Martian riding environment. Pumice is both beautiful and brutal — it destroys tires and slows momentum on descents.

The final section through the Cascades takes you through the Three Sisters Wilderness corridor, past Waldo Lake (one of the purest lakes in the world), and into the dense Douglas fir forests of southern Oregon before ending near the California border.

Key Challenges

Resupply is genuinely difficult on the OTT. Several sections are 80–100+ miles from any town with a grocery store. Pre-shipped food packages to small-town post offices are the only reliable strategy for the remote central Oregon stretch. Download the OTT's resupply guide from the Alliance website before you go.

Tire selection is not a minor decision. The pumice sections of central Oregon are extraordinarily sharp and will flat conventional clinchers repeatedly. Tubeless with quality sealant is not optional — it is the only approach that works. Carry plugs, patches, and a CO2 system in addition to a hand pump.

Water in the central Oregon volcanic sections can be surprisingly scarce despite the forested appearance. Carry more than you think. The lava rock absorbs snowmelt quickly, and springs marked on maps may be seasonal.

The Wallowas section in early season (before late June) can hold significant snow on north-facing slopes. Check with the Wallowa-Whitman National Forest ranger station for current conditions if you're riding before July.

Best Time to Go

July through September is the reliable window. The Wallowas are often not rideable until early July due to snowpack. August and early September are ideal — trails are dry, temperatures are manageable, and the fall colors begin arriving in the higher elevations by mid-September. Smoke from western wildfires is a real factor in August. Monitor air quality before committing to exposed ridge riding in heavy smoke.

Gear Notes

A mountain hardtail or a capable gravel bike with 2.2-inch minimum tires is required. A full-suspension bike is a joy in the technical sections but adds weight to the climbs. Most OTT bikepackers run a 29er hardtail with a frame bag, handlebar bag, and seat pack setup in the 15–20 lb total loaded weight range.

Carry a comprehensive tool kit. You will be many hours from a bike shop for long stretches. A chain breaker, spare links, spare derailleur hanger (specific to your bike), and the ability to do basic cable repairs are non-negotiable.

How Others Did It

FKT records hover around 6–7 days for the fastest riders, though these are exceptional efforts by professional-level bikepackers. Most people who thru-ride the OTT take 12–20 days, allowing for rest days, a few town stops, and the occasional weather delay. The OTT Alliance Facebook group has active beta sharing with current conditions from riders on the route.
