Afton WY to Havre MT: Scenic Drive Guide & Hidden Gems

Crossing from Afton, Wyoming to Havre, Montana, you'll traverse the Wyoming Range, the Snake River Plain, and the high plains of central Montana—a 445-mile journey that takes about 7 hours of pure driving time. The route begins at an elevation of 6,240 feet and ends at 2,500 feet, offering a dramatic shift in climate and landscape.

The most iconic landmark you'll encounter is the Afton Antler Arch, spanning Main Street with over 3,000 elk antlers—a unique testament to the region's wildlife legacy.

Just south of Afton, the route clips the edge of the Bridger-Teton National Forest, where you can detour to Granite Creek Hot Springs, a mineral pool set against a rugged canyon.

As you follow the Snake River toward Jackson, the Tetons loom to the east, but the true highlight is the Grand Tetons themselves—a UNESCO World Heritage Site that's part of the Greater Yellowstone Ecosystem.

Once in Idaho Falls, the Snake River Greenbelt offers a serene riverside walk, and the Idaho Falls Temple's illuminated spires are a local landmark.

Further north, the sagebrush plains and buttes signal the approach to Montana's vast open spaces. The towns along the way—Ashton, St. Anthony, Rexburg—are agricultural hubs where you can sample local honey or visit a roadside stand. In Montana, the Hi-Line region is known for its grain elevators and historic railroad towns; Havre's business district boasts original brick storefronts and the iconic Havre Daily News building.

Today, the most reliable route is a combination of US-89, US-26, I-15, and US-87. While the drive is manageable, you'll find that fuel stops are sparse between towns, especially in the 120-mile stretch from Idaho Falls to Dillon, Montana—plan accordingly.

• Fuel costs: Expect to pay $3.50‐$4.00 per gallon; a car averaging 25 mpg will need about 18 gallons, costing between $63 and $72 one-way.
• Road conditions: I-15 is well-maintained, but US-89 and US-87 are two-lane highways with sections of rough pavement, especially near the Montana-Idaho border.
• Weather hazards: Snow and ice can persist into June in the high passes, and high winds are common on the plains in spring and fall.
