Mountains. Rivers. Solitude.
The Klamath Mountains Loop begins in Ashland, Oregon, a vibrant college town celebrated for its lively arts scene and the renowned Oregon Shakespeare Festival. Enjoy the comforts of civilization while you can; the route quickly leaves pavement and people behind as it climbs into the remote highlands of the Siskiyou Crest. At over 7,000 feet, the surrounding views are nothing short of incredible.

The descent from the Crest brings you to the mighty Klamath River, a crystal-clear Wild & Scenic waterway that drains a major portion of northern California and southern Oregon. Following the final demolition of four hydroelectric dams in October 2024, the Klamath returned to its natural free-flowing state for the first time in 106 years, restoring more than 420 miles of salmon habitat throughout the watershed. The route snakes alongside the river for 57 miles, offering countless opportunities to admire its beauty, or even slip in for a refreshing dip.
After many miles following the canyons carved by the Klamath and its tributary, the Salmon, the route returns to the rugged mountains with a steep, remote gravel ascent up Eddy Gulch to Blue Ridge. Traces of gold mining still scar the landscape, a reminder of a bygone era when the region buzzed with activity. Today, you’re unlikely to encounter another sole as you make your way toward Eddy Gulch Lookout, where breathtaking 360° views await. The South Fork and Etna Summit Alternates are included as paved options to avoid the challenging climb over Blue Ridge.
Another climb over Carter Meadows Summit leads to Callahan and the southern edge of the Scott Valley. Sheltered in the rain shadow of the western mountains, the valley unfolds into a broad expanse of farmland and historic ranches, a welcome change from the narrow, forested canyons earlier on the route. The small town of Etna, a popular resupply point for Pacific Crest Trail hikers, makes an ideal stop to stock up on groceries or spend the night.
The route follows the Scott River to its confluence with the Klamath, returning riders to the main river as they continue upstream alongside its waters for 17 miles. Vast wildfire scars dominate the surroundings, and the landscape feels noticeably drier and more expansive than the lower canyons of the Klamath River. One final climb to Toll Road Gap along the southern flank of the Siskiyou Crest returns the route to Oregon, completing the loop in Ashland.

TERRAIN
The main route features three distinct mountainous sections: the Siskiyou Crest, Blue Ridge/Carter Meadows Summit, and again over the southern flank of the Siskiyou Crest. The climbs and descents are challenging, in both elevation gain/loss and steepness. The initial climb from downtown Ashland to Mount Ashland ascends nearly 4,700 feet over just 15.6 miles. The climb up Blue Ridge toward Eddy Gulch Lookout is especially steep, with maximum grades reaching 21%. While the summit rewards riders with incredible views, the South Fork or Etna Summit alternates provide options to bypass some of this extra climbing. Regardless of the chosen route, every option departing Forks of Salmon involves significant climbing to reach Etna. Although slightly higher in elevation, Carter Meadows Summit (elev. 6,207 ft.) offers a more gradual climb compared with Etna Summit (elev. 5,987 ft.)
Between these major climbs, the route is generally flat or gently graded as it follows the river canyons.
Overall, the main route is 64% paved and 36% unpaved. Both alternate routes and the spur into Medford are fully paved.

LOGISTICS
The route formally begins and ends in Ashland, Oregon, but you can start and finish anywhere on the loop that is most convenient to you. Ashland makes an excellent launching point thanks to its accessibility and wide range of accommodations and services. For those flying in, Rogue Valley International-Medford Airport is located 17.4 miles north of Ashland in Medford. The Medford Airport Spur follows the Bear Creek Greenway and offers an easy, pleasant connection to the loop’s starting point in Ashland.
The route was originally designed and researched counterclockwise but can be ridden in either direction. There are no significant advantages or drawbacks to choosing one direction over the other.
This route can be ridden anytime between early summer and fall (typically mid-June through October). Depending on the severity of the previous winter, snowfields and drifts can linger on the high-elevation ridges of the Siskiyou Crest well into June. The highest point on the route is near Observation Peak on the Siskiyou Crest at 7,061 feet, just north of the Oregon-California border.
Conversely, the lower canyons of the Klamath River can be swelteringly hot during the summer months. July and August are the hottest periods, with average highs in the mid-90s and record temperatures reaching up to 115°F in Happy Camp. The lowest elevation on the route is near Somes Bar, only 542 feet above sea level. To avoid both the intense heat of the lower canyons and lingering high-elevation snow, the best time to ride is often September and October, with a possible narrow window in late-June.
Wildfire is a very real concern along the entirety of this route, as evidenced by several large burn scars visible along the way. Fire season typically peaks from July through October, which unfortunately overlaps with the ideal riding season. Because conditions vary from year to year, riders should regularly check current wildfire status through the National Interagency Fire Center at advcy.link/fireinfo. Ranger stations in Happy Camp and Fort Jones can also provide up-to-date information on active fires and local fire danger.
Careful resupply planning is essential on this route due to its remoteness. While camping opportunities are plentiful, most services are concentrated in just four towns: Ashland, Happy Camp, Etna, and Fort Jones. It is 128 miles between Happy Camp and Etna, with only limited convenience stores available in Somes Bar and Callahan along the way.
Surface water is plentiful along most of the route, but should always be treated or filtered before drinking.
The ideal bike for this route is a bike that’s comfortable on gravel but still efficient on pavement. A gravel bike designed for long-distance with the largest tires you can fit, at least 45mm, is a solid choice to keep the ride smooth and enjoyable.
