Havre to Alpine Road Trip: Stops, Times & Worth It

Starting in Havre, Montana, known for its historic Great Northern Railway roundhouse, and ending in Alpine, Wyoming, gateway to the Snake River Canyon, this drive traverses the Hi-Line, the Rocky Mountain Front, and high desert plains.

US-87 and I-90 are the primary arteries, with an estimated drive time of roughly 10 hours and 650 miles. The route passes through diverse ecosystems, from prairie grasslands to pine forests and alpine peaks.

Fuel economy: Montana has lower gas taxes, but Wyoming's can vary; plan for a fill-up in Butte and Idaho Falls. Road conditions are generally excellent on interstates, but rural stretches can be narrow with minimal shoulders.

Most services (gas, food, lodging) are clustered in towns along I-90 and US-26. Beyond these corridors, expect long gaps between services – carry at least half a tank of fuel when detouring.

• Road quality: I-90 is well-maintained; US-287, a scenic alternative, has chip-and-seal sections.
• Tolls: none on the route.
• Weather closures: passes like Homestake and Teton can close in winter.
• Wildlife: watch for deer and elk at dawn/dusk.

For families, the Museum of the Rockies in Bozeman features dinosaur exhibits, and the Grizzly & Wolf Discovery Center in West Yellowstone are educational. Many rest areas have picnic tables and playgrounds.

Pet-friendly: Most hotels along the route allow pets; however, national parks prohibit pets on trails, so plan accordingly. There are several off-leash dog parks in Bozeman and Idaho Falls.

Fatigue: Take breaks at designated rest areas every two hours; the Montana State Line Rest Area near the start is a good first stop.

Hidden spots: The town of Ennis offers a quiet fly-fishing pond, and the Menan Buttes near Idaho Falls are volcanic craters accessible via a short dirt road.

Seasonal: In autumn, the cottonwood trees along the Madison River turn gold – a scenic highlight.

Yellowstone National Park, a UNESCO World Heritage Site, is a major detour near the route's southern end. Also, the Head-Smashed-In Buffalo Jump (in Alberta, Canada) is not on the route, but the nearby First Peoples' Buffalo Jump State Park near Ulm offers similar cultural history.

Geology: The route crosses the Rocky Mountain Front, where the Lewis Overthrust is visible – ancient rock pushed eastward.

Short detours: Lewis and Clark Caverns State Park (near Whitehall) offers cave tours, and the Virginia City ghost town preserves gold-rush era buildings.

Culinary stops: Try huckleberry shakes in Wisdom or a pasty in Butte, a nod to Cornish miners. Local breweries are in Bozeman and Idaho Falls.

Local commerce: Farm stands sell fresh produce in the Bitterroot Valley, and artsy shops in Livingston and Driggs showcase regional crafts.
