Trans-America Trail — Dillon to Missoula via the Anaconda-Pintler Wilderness Divide

Big sky, no crowds, Continental Divide dirt.

Moderate

Sam Correro’s Trans-America Trail runs some of its most dramatically lonely miles across southwest Montana, linking Dillon north through the Beaverhead-Deerlodge National Forest before cresting the Continental Divide fringe near the Anaconda-Pintler Wilderness. The route stitches together forest service two-track, old mining access roads, and gravel county byways, passing through the ghost town environs of Wisdom and crossing the Big Hole Valley floor before the terrain tilts upward again toward the Skalkaho Pass road — a standout moment of exposed switchbacks with sheer drop-offs on one side and a wall of spruce on the other. Wildlife density here is high; moose, black bear, and elk share the road with regularity. Georgetown Lake sits mid-route and is a reliable fuel and camp-water stop.

A stock high-clearance 4WD handles this segment in dry summer conditions, but the window is narrow — snow closes the higher forest roads by mid-October and the pass can hold drifts into late June. Run it July through September. GPS with downloaded TAT tracks from the official source is mandatory; forest service signage is inconsistent and logging traffic sometimes obliterates two-track with fresh ruts. Fuel up in Dillon and again in Anaconda or Philipsburg — gaps exceed 80 miles on the back sections. Cell service is spotty to nonexistent in the National Forest interior. What you take home from this one is big sky Montana in its rawest form, with almost no other overlanders in sight.

Frequently asked questions

Can a stock 4Runner or Wrangler run this segment without modifications?

Yes — stock high-clearance 4WD handles this segment fine under normal summer conditions. Skid plates are worth having given the rocky jeep tracks near the Anaconda-Pintler high country, but lifts and lockers aren't required.

When does this route actually open and close each year?

July through September is your window. Snow lingers on the high passes into late June, and early October storms can shut things down fast. Check with Beaverhead-Deerlodge National Forest for current road conditions before you roll out.

Do I need a permit or is there a fee to drive this route?

No permit or fee is required to drive the route through Beaverhead-Deerlodge National Forest. Dispersed camping is free; follow Leave No Trace and stay out of any posted wilderness zones where motorized travel is prohibited.

What's the hardest section and what should I expect?

The climb through the Anaconda-Pintler high country is where the trail tightens up — narrow two-track, loose rock, and limited turnaround space. Nothing extreme, but it demands attention; a single wrong line can put a rocker panel on granite at 7,000 feet with no one around to help.

How far is it between reliable fuel stops on this 210-mile segment?

Dillon has full services at the start; Anaconda and Missoula cover the finish. The middle stretch has nothing — carry enough fuel for 150+ miles of low-gear mountain driving, which burns significantly more than highway estimates suggest.
