Park City to Bozeman Road Trip Guide: Mountains, Wildlife & Gems

Utah State Route 224 meets Interstate 80 in Park City, a former silver mining town turned world-class ski resort. The 600-mile drive to Bozeman, Montana, crosses three states and gains nearly 5,000 feet in elevation. You'll traverse the Bear River Range, the Snake River Plain, and the Madison Range before descending into the Gallatin Valley.

This route shadows the 40th parallel north for a stretch before veering northwest at Idaho Falls. It takes roughly 9–10 hours of pure driving, but plan for two days to savor the landscapes. The route's remote stretches offer few services, so fuel and snacks need planning.

For those wondering how to find the best stops and hidden gems between cities, this guide breaks down every mile.

Route Overview Table

This drive skirts two UNESCO sites: Yellowstone National Park (World Heritage Site) and the adjacent Grand Teton National Park. Though not directly on route, a short detour to Grand Teton's northern entrance via US-26/89 is 30 miles from Idaho Falls.

The landscapes shift from Utah's red-rock canyons and Great Salt Lake wetlands to Idaho's volcanic Snake River Plain, dotted with cinder cones and lava flows. Near West Yellowstone, the Madison River offers world-class fly fishing and views of the Gallatin Mountains.

• Bear River Migratory Bird Refuge near Brigham City: 80,000 acres of wetlands, free entry
• Lava Hot Springs, ID: natural hot springs 20 mi off I-15, perfect soak
• Craters of the Moon National Monument: detour 60 mi west of Idaho Falls, lunar-like landscapes
• Mesa Falls Scenic Byway (US-20): Upper and Lower Falls, 2 hours of hiking
• Yellowstone National Park: West Entrance at West Yellowstone, geysers and wildlife

Local commerce includes artisanal cheese in Idaho Falls (e.g., Darigold store), fly shops in West Yellowstone, and Bozeman's thriving downtown with galleries and breweries. The route passes through Shoshone-Bannock tribal lands; the Fort Hall Reservation near Pocatello offers bison burgers and powwows in August.

For a unique souvenir, stop at the Teton Valley Trading Company in Driggs, Idaho, just 10 miles off US-20. They produce huckleberry products, syrup, and jam.

The route comprises I-80 east from Park City to Ogden, then north on I-15 through Idaho Falls. At Monida, you'll head east on US-20 through West Yellowstone, then north on US-191 to Bozeman. The final stretch from West Yellowstone to Bozeman is a winding two-lane road through Yellowstone National Park's northern boundary and the Gallatin National Forest.

Gas stations cluster around major towns: Ogden UT; Pocatello, Idaho Falls, and Rexburg ID; West Yellowstone and Bozeman MT. Stretches like US-20 between Idaho Falls and West Yellowstone (95 miles) have few services. A fuel stop at St. Anthony or Ashton is prudent.

• Park City to Ogden: 40 min, I-80
• Ogden to Pocatello: 1.5 hr, I-15
• Pocatello to Idaho Falls: 45 min, I-15
• Idaho Falls to West Yellowstone: 2 hr, US-20
• West Yellowstone to Bozeman: 1.5 hr, US-191

Cell coverage is weak east of Idaho Falls; download offline maps. Wyoming's part of the route (only a sliver near Yellowstone) has limited service. A paper atlas is a wise backup.

The best time to drive is June through September when mountain passes are snow-free. Winter driving requires chains or 4WD, and parts of US-191 close temporarily during storms. Check road conditions at 511 for both Montana and Idaho.

US-191 from West Yellowstone to Bozeman is a narrow, winding road with sudden wildlife crossings (elk, bison, bears). Drive at posted speeds (55 mph max) and use high beams in forested areas at dawn/dusk. The road has no shoulders in many sections.

Recommended rest zones every 2 hours: Ogden's 25th Street historic district, Idaho Falls' Greenbelt along the Snake River, and Ashton's city park (picnic tables). For longer breaks, Bozeman's Story Mill Park has trails and restrooms.

• Family-friendly stop: The Yellowstone Giant Screen Theater in West Yellowstone
• Pet-friendly: Most Idaho rest areas have dog runs; Bear World in Rexburg allows leashed pets (outdoor areas)
• Fatigue buster: Window-down stretches on US-20 near the Henrys Fork of the Snake River (milepost 340-360)

Culinary stops range from fast food in Idaho Falls (Idahoan baked potato chain) to gourmet at Bozeman's Plonk (New American). For a picnic, buy huckleberry muffins at the West Yellowstone bakery. Idaho Falls has a farmer's market on weekends (May-Oct).

Hidden off-route spots: Hell's Half Acre lava field (Idaho Falls exit 119, 5-mile dirt road) or the Red Rock Pass overlook on US-20 (historic Bonneville flood route). Both offer solitude and photo ops.
