Price to Dillon: A Scenic Utah-Montana Road Trip Guide

The route from Price, Utah to Dillon, Montana spans roughly 500 miles, crossing the high desert, the Wasatch Range, and the Snake River Plain before ascending into the Rocky Mountains. A key historical fact: this corridor parallels the old Mormon Trail, used by pioneers in the 1840s.

Driving time averages 8-9 hours without stops, but most travelers take two days to savor the landscape. This guide covers everything from fuel costs to family-friendly stops.

From Price, head north on US-191, joining I-15 at Spanish Fork. Continue north through Salt Lake City, Ogden, and into Idaho. At Idaho Falls, take I-15 north to exit 118 for Dillon, then follow MT-41 for the final 55 miles.

Fuel prices vary significantly: expect lower costs in Utah (around $3.50/gallon) and higher in Montana (approaching $4.00). Plan to fill up at major towns like Provo, Pocatello, and Idaho Falls.

• Total driving time: 8-9 hours
• No tolls on this route
• I-15 is well-maintained, US-191 in Utah has some winding sections
• Cell coverage is spotty between Provo and Spanish Fork, and on MT-41

For real-time road conditions, check the Utah DOT and Montana DOT apps. Winter driving from November to March can require chains; check weather forecasts before departing.

If you're wondering is it worth driving Price, UT to Dillon, MT? Absolutely—the scenic variety justifies the distance.

Road quality is generally good, but watch for wildlife, especially deer and elk, during dawn and dusk. In winter, black ice is common on shaded mountain passes.

For families, the Brigham City Dinosaur Park (in Brigham City, Utah) is a great break, with life-sized dinosaur replicas and a playground.

Idaho Falls offers the Idaho Falls Zoo and the beautiful Snake River Greenbelt—perfect for a picnic.

For dogs, many rest areas on I-15 have designated pet-run areas. The Beaverhead Rest Area in Montana is particularly spacious.

Fatigue management: take a break at least every two hours. The Utah Rest Area at Willard Bay has scenic views to refresh you.

Hidden off-route spot: The Lava Hot Springs in Idaho are only 10 miles from I-15—ideal for a relaxing soak.

Shortly after Price, the San Rafael Swell offers dramatic sandstone canyons—a hidden gem for hiking. In Utah, the Wasatch Front provides a stunning backdrop as you drive past Mount Nebo, the highest peak in the Wasatch Range.

Crossing into Idaho, the landscape flattens into the Snake River Plain, with vast lava fields near Arco. The Craters of the Moon National Monument, although slightly off-route, is a must-see for its volcanic terrain (adds 2 hours round-trip).

Local commerce along the way is characterized by small-town diners and family-owned gas stations. In Malad City, Idaho, stop at the Bluebird Cafe for classic American pies.

In Dillon, the Beaverhead County Museum showcases pioneer history. The town's economy revolves around agriculture and ranching.
