Ride the Rock Creek Skalkaho Loop
From Missoula, climb Rock Creek’s canyon and Skalkaho Pass, then descend to Hamilton and ride the Bitterroot Trail back. Expect 5 interstate miles and 93 with no resupply.
What to Expect
Remote, committing, and deeply rewarding. This is a Short Route for riders with touring experience, durable equipment, and the judgment to manage a long service gap and mountain weather.
Rock Creek’s forested canyon, the climb over Skalkaho Pass, and nearly 50 miles beneath the Bitterroot Mountains create three distinct acts. Along the way, riders follow one of Montana’s celebrated trout streams and pass the roadside cascade of Skalkaho Falls, before the protected Bitterroot Trail brings the route gradually back into town.
The loop covers 167.7 miles with 6,354 feet of climbing. The centerpiece is a steady climb to Skalkaho Pass, above 7,000 feet, with rough gravel and long descents before the flatter Bitterroot Trail. Expect a narrow, forested creek canyon, high subalpine forest near the pass, and wide ranch valleys with mountain views to the west.
There is no on-route resupply between Rock Creek Road and Hamilton, roughly miles 27 to 120. Much of the route has limited cell service, primitive camping, and no quick mechanical support.
Late spring through early fall is the practical season, depending on snow and road conditions at Skalkaho Pass. Mountain weather can bring cold rain or snow even in summer, while lower valleys can be hot.

Plan Your Ride
Allow several days, confirm that Skalkaho Pass and forest roads are open, and leave Missoula or Clinton with enough food for the long gap to Hamilton.
Trip Planning & Logistics
The loop begins and ends in Missoula and includes about 5 miles of interstate riding. Check Montana road conditions, Lolo National Forest notices, and pass conditions immediately before departure. Build flexible days around the primitive campgrounds.
Use a gravel or mountain-capable touring bike with low gears and durable tires. Carry water treatment, extra food, bear-safe storage, layered clothing, lights, navigation backup, and equipment for independent repairs.
Numerous U.S. Forest Service campgrounds line the route, most primitive and first-come, first-served. A small number of rental cabins may be available. Indoor lodging is concentrated in Missoula, Hamilton, and other Bitterroot Valley communities.
Stock up in Missoula or Clinton. Carry all food needed through the roughly 93-mile service gap to Hamilton, plus an emergency reserve. Treat water collected from natural sources.
Expect remote riding, changing gravel, wildlife, and rapidly changing mountain weather. Store food securely in bear country. The interstate segment requires high visibility and traffic awareness. Do not attempt Skalkaho Pass when snow, fire, or road closures make travel unsafe.
Routes change. Bridges wash out, businesses close, and construction pops up overnight. We strive to keep routes updated as those things happen. When we learn about a change, we reroute around sections that have become dangerous, update service information as businesses open, close, or move, and reroute around temporary road and bridge closures or construction. Digital routes are updated as soon as we’ve reviewed a reported issue.
You’re often the first to spot these changes out on the road. Help us keep this route accurate for the next rider by reporting anything you notice with our Route Feedback Form.

Frequently Asked Questions
A collection of free, cyclist-submitted routes built for shorter trips. Each route is designed for a trip of one to five nights, ranging from a quick overnight ride to a longer multi-day adventure. It’s the most accessible of our three route networks: no purchase required, no advanced experience assumed, just a well-vetted route you can ride over a weekend or a week off.
We launched Short Routes in August 2022 with an initial set of 12 routes, created specifically because our epic, long-distance routes don’t work for everyone. Someone with a week of vacation, or someone new to bike touring, needs a different starting point. We developed that first collection in partnership with BIPOC, LGBTQ+, women, and intersex cyclists, with routes centered near major cities like Los Angeles, Seattle, Minneapolis, Austin, Atlanta, Washington, D.C., Philadelphia, and Boston, so people could find a route close to home rather than needing to travel somewhere remote first. Since then, the collection has grown through rider submissions and partnerships with other organizations like East Coast Greenway Alliance.
It’s the only one of our three networks built primarily by the community, for the community. Typically, the route builder is local to the area, providing special knowledge about transportation logistics, services, points of interest, and more. Anyone can submit a route, but every submission goes through a staff review: checked for traffic speeds, shoulder width, surface conditions, and whether services like food, water, and camping are realistically spaced for a loaded touring bike.
Riders who don’t have weeks to spend in the saddle, and riders who’ve never done a multi-day bike trip before. The collection was built with input from locals and includes routes near major cities, so that cyclists who live far from the endless miles of gravel roads or remote bikepacking routes have great routes mapped near them.
No. Many of our Short Routes are built to be beginner-friendly, though all are worth riding no matter your experience level. Because each one runs just one to five nights, it’s a much lower commitment than a cross-country tour, which makes it a good place to start if you’ve never done a multi-day ride.
Anyone can submit. You don’t need any official affiliation with Adventure Cycling. Head to our route submission form, and come prepared with three things: at least 10 photos from the route, a written description covering the highlights, navigation notes, services along the way, seasonal considerations, and a short bio about you as the route’s creator, and a Ride with GPS route that includes automatic cuesheetsand custom points of interest for things like lodging, food, bike shops, and any hazards.
It needs to take a beginner one to five nights, cover 50 to 200 total miles, and be located anywhere in the U.S. or Canada. Beyond that, we’re mainly checking for safety. A route can’t put a fully loaded touring cyclist through excessive hazards, so we look at things like traffic speed, shoulder width, road surface, and whether food, water, and camping are realistically spaced along the way.
It helps if you rode it within the past year or so. Those submissions move through review faster, since conditions on the ground are more likely to still match what you’re describing. Older routes can still be submitted, but they may take longer to review since we may need to double-check that services and conditions haven’t changed.
Review typically takes several weeks. We check every submission for safety and accuracy and reserve the right to edit before publishing. If your route is approved, we’ll follow up with you by email.
