Havre to Athol Road Trip: Routes, Stops & Hidden Gems

The drive from Havre, Montana, to Athol, Idaho, roughly 500 miles, follows the ancient path of the Missouri River and the Mullan Road, a historic military wagon route. The most direct path is via US-2 West to Shelby, then I-15 South to Helena, and US-12 West through MacDonald Pass into Idaho.

This route takes you through the Continental Divide twice, offering a geological cross-section of the Northern Rockies. Expect a driving time of about 8 to 10 hours without stops, but plan for at least two days to enjoy the journey.

Wildlife crossings are frequent on US-12, especially at dawn and dusk. Keep an eye out for deer and elk. The route has several designated scenic overlooks; take breaks at rest areas like the one at MacDonald Pass.

For families, the carousel in Missoula's Caras Park is a hit, and the historical museum at Fort Missoula has interactive exhibits. Pets are welcome at most rest areas but not in state parks; check signs.

To avoid fatigue, schedule a stop every two hours. Explore hidden gems using how to find the best stops and hidden gems between cities. Consider an overnight in Missoula to break the drive.

The highways are well-maintained, but winter conditions can be treacherous. US-12 over MacDonald Pass is steep and winding; check road conditions at MT 511. I-90 from Missoula to Coeur d'Alene is a four-lane freeway, the only section with rest areas every 30 miles.

• Fuel stations are sparse between Havre and Shelby (70 miles) and Garrison to Drummond (40 miles). Plan to fill up in larger towns.
• As of 2024, gasoline averages $3.80/gallon in Montana and $4.20 in Idaho. Budget around $120 for the trip.
• No tolls are on this route.

The route passes through the Lewis and Clark National Forest, where you can stop at the Gates of the Mountains Wilderness for a boat tour. Near Drummond, the Garnet Ghost Town offers a glimpse into Montana's gold rush era. In Idaho, the Cataldo Mission, built in 1853, is the oldest standing building in the state.

For local flavor, stop at the Trestle Creek General Store in Hope, Idaho, which serves huckleberry milkshakes. In Thompson Falls, the historic Falls Motel offers diner-style meals.
