Bitterroot Divide Continental Crest Trail
Continental Divide logging roads through big timber
The Bitterroot Divide runs the spine between Montana and Idaho along old logging spurs and mining access roads that crisscross the Continental Divide. Starting near Lolo Pass, this network of Forest Service roads threads through dense timber and alpine meadows, hitting waypoints like Nez Perce Pass and the old Ward Creek lookout site. You’ll cross the divide multiple times on roads that range from well-maintained gravel to rutted two-track with embedded rocks and seasonal mud holes.
Moderate difficulty with some technical sections requiring high-clearance 4WD and careful line choice around stumps and washouts. Best driven July through September when snow clears above 6,000 feet. No permits needed on Bitterroot National Forest roads, but fuel up in Missoula—nearest services are 40+ miles away once you’re committed. Abundant dispersed camping along ridgelines with views into both Montana valleys and Idaho wilderness. This is classic Montana backcountry: big timber, bigger views, and the kind of solitude that reminds you why you bought that truck.

Frequently asked questions
Can a stock Tacoma or 4Runner handle this trail, or do I need a lift?
A stock high-clearance 4WD handles it fine. The logging roads are rough but not technical — you need ground clearance and low-range, not a built rig. A lifted setup just gives you more peace of mind on the washboarded sections.
When does the Bitterroot Divide route actually open after winter, and when does it close?
July through September is the reliable window. Snowpack at 7,100 feet can keep upper sections blocked well into June, and early October storms can shut things down fast. Check current road conditions with Bitterroot National Forest before you roll.
Do I need any permits or passes to run this route?
No permit required for vehicle travel or dispersed camping on Bitterroot National Forest land. Standard Leave No Trace rules apply — no fees, no registration, just follow forest road regulations and fire restrictions, which change seasonally.
What's the hardest section of the trail and what makes it gnarly?
The steeper ridge climbs between Lolo and the mid-route high points are where things get honest — loose gravel, off-camber shelf road, and no guardrails with serious exposure. It's moderate overall, but those sections punish inattention and reward slow, deliberate driving.
How far is the nearest gas from the trail, and should I carry extra fuel for this route?
Missoula is your last reliable fuel stop before the northern trailhead, and Hamilton covers the southern end near Lost Trail Pass. At 45 miles of slow forest driving, carry at least a 5-gallon auxiliary can — there's nothing in between and cell service is zero the entire route.
