Drive from Columbia Falls, MT to Pinedale, WY: Route Guide

The drive from Columbia Falls, MT to Pinedale, WY covers roughly 670 miles, typically taking about 10.5 hours of pure driving. This route crosses the Continental Divide twice, traversing the wild landscapes of Montana and Wyoming.

You'll follow US-2 East, then I-90 East, and finally US-287 South into Wyoming. The journey showcases the dramatic transition from the Rocky Mountain front to the high desert of the Green River Basin.

Fuel costs average $0.12 per mile for a typical sedan, totaling about $80 for the trip. Gas stations cluster in towns like Missoula, Butte, and Dubois, so plan to fill up when you see them.

• I-90 through Montana is well-maintained, with rest areas every 50-60 miles.
• US-287 in Wyoming is less traveled; services are sparse—carry extra water and snacks.
• Road construction is common during summer; check Montana DOT and Wyoming DOT alerts before departure.

Drive times exceed 10 hours, so schedule breaks every 2 hours at rest areas or small-town parks. For families, the Children's Museum of Montana in Great Falls is a popular diversion, while pets are welcome at many rest stops, but keep them leashed.

Watch for wildlife, especially deer and elk, at dawn and dusk. Mountain passes like Homestake Pass near Butte can be windy; slow down and use lower gears.

The route passes near Glacier National Park, which is a UNESCO World Heritage Site, though the park is actually north of Columbia Falls. Farther south, Yellowstone National Park, also a UNESCO site, lies just east of the route near Cody, WY.

Local commerce thrives in towns like West Yellowstone, where you'll find outfitters and cafes. The how to find the best stops and hidden gems between cities can help you plan detours.
