In this guide
Klamath County has a trail system that riders in Bend and Ashland know about and most people outside the region do not. That is the appeal and it is also why the information online about it is thin and often out of date.
So here is what the trail organisation that actually builds and maintains these trails says, and where we could not verify something, we say that instead of making up a number.
Spence Mountain
Klamath Trails Alliance describes Spence as over 50 miles of singletrack, 15 miles west of Klamath Falls on the shores of Upper Klamath Lake, and calls it one of Oregon's up-and-coming mountain bike destinations. E-bikes are allowed.
What makes it work is the combination: purpose-built flow trail with technical options off it, lake and Cascade views from the upper trails, and enough mileage that you can ride a different line each day for a long weekend. Bald eagles and deer are ordinary sightings rather than an event.
New trail keeps going in. Badger and Chinquapin have both opened recently, with Chinquapin built as an intermediate flow trail, and KTA has been improving both trailheads with more parking at the Highway 140 trailhead.
A note on trail names and stats. Several guides publish a precise mileage, an elevation range and a list of named trails for Spence. We could not confirm those against KTA, whose own figure is the softer over-50-miles. Pull current trail names and status from the Klamath Trails Alliance site or from Trailforks and MTB Project rather than from a blog post written three years ago, this one included.
Moore Mountain
The in-town system. Moore Mountain sits minutes from downtown Klamath Falls, close enough that you can ride to the trailhead from a hotel rather than driving to it, and low enough in elevation that the season runs longer at both ends than the higher systems.
KTA lists it as one of the four main trail systems in the county. We were not able to retrieve their Moore Mountain page to confirm mileage or current trail names, so rather than repeat figures we cannot source, the useful advice is to pick up the free Klamath Trails Pocket Map. It covers all four systems and is available at Zack's Bikes, Discover Klamath and A Leap of Taste.
Brown Mountain and the Volcanic Country
The backcountry end of the spectrum, out in the Fremont-Winema National Forest. This is volcanic rock, old growth and genuinely technical ground, and it rides best from late summer into early fall once things dry out and before the weather turns.
Treat this differently from the built systems. It is national forest, which means live fire closures, road closures for culvert work and seasonal public use restrictions that change through the summer. The forest has had fire-area emergency closures and Stage 1 and Stage 2 restrictions in place this season. Check the Fremont-Winema alerts page the morning you go, not the week before.
The OC and E Woods Line State Trail
Oregon's longest linear park, 100 miles built on the railbed of the Oregon, California and Eastern Railroad. Construction started in July 1917, reached Sprague River by 1923 and Bly six years later; logging use ended in 1990 and Weyerhaeuser railbanked the right of way to the state.
It is gravel-bike and mountain-bike ground rather than singletrack, open to hiking, biking and horses, and open in all seasons to non-motorized use.
| Section | Distance | Surface |
|---|---|---|
| Urban, Klamath Falls to Olene | 7.6 miles | Paved. Toilets at Reeder Road and Wiard Park |
| Gateway, Olene to Sprague River | 31 miles | Gravel |
| Sprague River to Bly | 24 miles | Loose rock. Flush toilet at the Bly trailhead |
| Woods Line Spur, Beatty to Sycan Marsh | 33 miles | Loose rock. Toilets at Horse Glade trailhead |
Two closures are live and both matter. A wildfire closure shut the trail from Dairy to Beatty in August 2026, with part of the trail under evacuation. And the entire Woods Line section has been closed since the Bootleg Fire in July 2021 and remains closed.
There is no drinking water anywhere on the OC and E. Carry everything you need. Only the first 36 miles from Klamath Falls carry the state regional-trail designation, which is why you will see both 36 and 100 quoted as its length.
Riding Smart Out Here
Two things separate a good day from a bad one in this county, and neither is fitness.
The first is checking status. Klamath Trails Alliance is the organisation that builds and maintains these trails, and their site is where current conditions live. For anything on national forest, the Fremont-Winema alerts page is the one that matters, because fire closures here are frequent and they move.
The second is water. This is high desert on one side of the county and volcanic plateau on the other. There is no water on the OC and E at all, and not much you would want to drink anywhere else. Carry more than the distance suggests.
Before you ride
Check Klamath Trails Alliance for trail status, and the Fremont-Winema alerts for anything on forest ground.
Pick up the free Klamath Trails Pocket Map at Zack's Bikes, Discover Klamath or A Leap of Taste. It covers all four systems.
Download offline maps. Cell coverage goes away quickly outside town.
Carry a repair kit for anything backcountry. Help is a long way off on the Brown Mountain end.
Yield to hikers and horses, especially on the OC and E where all three share the corridor.
Ride the built systems in spring through fall. Brown Mountain wants late summer into early fall.
One correction worth making, because it circulates: Dirt Mechanics is not a bike shop. It is a recreational excavation company that builds and designs trail, and it has been doing the construction work at Spence Mountain. The local shop that Klamath Trails Alliance names as a partner is Zack's Bikes.
When to Ride
| Season | Conditions | Where |
|---|---|---|
| Spring | Wildflowers, mild temperatures, some mud at elevation | Moore Mountain first, Spence as it dries |
| Summer | Long days, dry trail, hot afternoons | Spence early and late; OC and E in the cool hours |
| Early fall | The best window of the year. Dry, cool, quiet | Everything, including Brown Mountain |
| Late fall to winter | Snow at elevation, lower systems hold on longest | Moore Mountain, and the urban OC and E section |
Moore Mountain's lower elevation is the reason it gets named as the season-extender at both ends. When Spence is under snow, town is often still rideable.
Riding From the Driveway
The thing that changes when you live here is not the trails. It is that a ride stops being a plan. Spence is fifteen minutes from a lot of ground in this county, and the OC and E starts downtown.
Klamath County runs 11.7 people per square mile across 5,950 square miles, and land is priced accordingly. We sell parcels on owner financing with no bank and no credit check. Down payments typically run $150 to $175, monthly payments typically $150 to $250 on terms of 60 to 96 months, with a document fee of $250 on most parcels. Every one is backed by the Peace‑of‑Mind Guarantee.
There is a 21-day camping limit on your own ground here, covered in camping, RVs and tiny homes. If you walk as well as ride, our hiking guide covers the wilderness areas, and the adventure sports guide covers what else operates in the county. Current inventory is on our Oregon land page. Our Klamath County parcels are spread around the county rather than gathered in one subdivision, mostly out toward Chiloquin, Beatty and Bonanza.
