Provo to Havre: Epic Road Trip Guide

Stretching 800 miles from the Wasatch Front to the Hi-Line, the drive from Provo, UT to Havre, MT crosses three states and six distinct ecoregions. The route follows I-15 north through Utah and Idaho, then I-90 east through Montana's gold-mining country, finally heading northeast on US-87 to the Milk River valley. Driving time without stops is roughly 12 hours, but plan for two days to appreciate the scenery.

How to find the best stops and hidden gems between cities starts at your own curiosity.

The most direct path uses I-15 north through Utah and Idaho, then I-90 east at Butte, and finally US-87 northeast to Havre. Speed limits range from 65 mph in Utah to 80 mph on most of I-90 in Montana. Winter travel can be hazardous, especially across Monida Pass (elevation 6,870 ft) and Homestake Pass, so check forecasts.

• Fuel: Major stations every 50-100 miles; fill up in Provo, Idaho Falls, Butte, and Great Falls—the longest gap is 75 miles between Malta and Havre.
• Food: All exits offer fast food; sit-down options in Pocatello, Bozeman, and Great Falls.
• Lodging: Overnight stops at Idaho Falls or Butte; Havre has several chain motels.

The route climbs from the Great Salt Lake desert to the sagebrush steppe of southern Idaho, then into the Rocky Mountains. The Montana section passes the Rocky Mountains' eastern front, the Missouri River headwaters, and the vast plains of the Hi-Line. This is cattle ranching and wheat country, with small towns like Dillon, White Sulphur Springs, and Lewistown offering local museums and grain elevators.

One UNESCO World Heritage Site lies off-route: Yellowstone National Park, 90 miles south of the I-90 corridor via US-191. It's the world's first national park and a geothermal wonderland.

Local commerce thrives along Main Streets in towns like Virginia City, a preserved gold rush town, and Havre's historic district with its 1913 Carnegie Library.

All interstate segments are well-maintained, but US-87 between Great Falls and Havre is a two-lane road with occasional gravel shoulders and wildlife crossings. Carry a spare tire and water. Montana is pet-friendly, but many national parks restrict pets; keep them leashed at rest areas.

• Family stops: Idaho Falls' Greenbelt, Yellowstone's Old Faithful, and Malta's Dinosaur Museum.
• Pet-friendly: Rest stops with leash areas at Pocatello and Butte.
• Fatigue: Take breaks every 2 hours; rest areas with picnic tables abound, and the Montana Rest Area at the Divide is particularly scenic.

Hidden off-route spots include the Berkeley Pit in Butte, a mile-wide toxic lake with viewing platform, and the Lewis and Clark Caverns State Park, 15 miles off I-90.
