Continental Divide Trail – Chief Joseph Pass
Nez Perce escape route through alpine granite
Chief Joseph Pass sits at 7,241 feet on the Continental Divide, marking where the Nez Perce crossed into Montana during their 1877 flight from the U.S. Army. This remote section of the Continental Divide Trail follows old mining roads and pack trails through the Bitterroot Mountains, connecting Lost Trail Pass to Big Hole Valley. You’ll navigate loose granite switchbacks, cross seasonal snowfields even in summer, and encounter the remnants of turn-of-the-century mining operations including collapsed cabins and rusted machinery scattered along Divide Creek.
This is expert-level terrain requiring full skid plates, recovery gear, and experience with high-altitude driving. Snow can persist until July, and afternoon thunderstorms roll in fast above treeline. No cell service for 40+ miles, and the nearest fuel is back in Salmon, Idaho. What you get is solitude in some of the most pristine alpine country in the lower 48, plus a piece of American history that most people only read about.

Frequently asked questions
Can a lightly modified 4Runner or Jeep handle this trail, or does it need serious buildup?
A lightly lifted rig with skid plates can manage it, but rock sections demand real articulation and at minimum all-terrain tires. Stock or mall-crawl builds will get hurt — frame damage and oil pan strikes are real risks here. Lockers are strongly recommended.
When does the trail actually become passable after winter, and how late into fall can you run it?
Snow typically clears from the high sections by early-to-mid July, though late snowpack years can push that to late July. By mid-October you're gambling on early storms closing the pass. July through September is the reliable window.
Do you need a permit to run Chief Joseph Pass, and are there any fees?
No permit is required to drive the trail itself through Bitterroot National Forest. Dispersed camping is free but follow Leave No Trace rules and check current fire restrictions with the Bitterroot NF before you go — fire bans hit this area hard in dry summers.
What's the hardest section of the trail and what specifically makes it technical?
The most punishing sections are the exposed granite shelf roads on the upper traverse — loose rock, significant drop-offs, and no room to turn around if you commit wrong. A single misread line can put a tire over the edge. Spotter communication and slow deliberate movement are non-negotiable here.
Are there water crossings and is there reliable water available for camp along the 28 miles?
Yes, there are water crossings — depth varies by season but early July crossings can run thigh-deep with fast current, so scout before you commit. Water sources exist along the route but treat everything — cattle and wildlife share this drainage. Carry at least a day's emergency supply regardless.
