Big Sky sits at 7,500 feet; Heber City at 5,600 feet. The route includes mountain passes up to 8,000 feet on US-20 between West Yellowstone and Ashton. Road conditions vary seasonally: winter requires 4WD or chains, while summer features construction along I-15 in Utah.

• Fuel stations are plentiful along I-15 but sparse on US-20 between West Yellowstone and Idaho Falls. Fill up in Big Sky or West Yellowstone before crossing.
• Electric vehicle charging is available in Idaho Falls (DC fast) and Logan, Utah. Plan for a top-up at these midpoint towns.
• Tolls: None on this route. All interstates and US highways are free.

Road Quality and Conditions

I-15 is well-maintained, with rest stops every 50 miles. US-20 is a two-lane highway with passing zones; watch for wildlife near Yellowstone. The segment through the Teton Basin near Driggs offers smooth pavement but frequent crosswinds.

Winter driving alerts: The Monida Pass on I-15 (milepost 190) is notorious for heavy snow. Check weather at wyoroad.info for Wyoming and itd.idaho.gov for Idaho. Summer brings roadworks around the Utah-Idaho border—expect delays up to 15 minutes.

This route threads iconic landscapes: the Gallatin River canyon, West Yellowstone’s volcanic plateau, the Teton Valley, and the Wasatch Mountains. Each region offers distinct natural attractions.

• Quake Lake (US-191): Formed in 1959, with a visitor center explaining the earthquake. Boardwalks provide views of drowned forestland.
• Mesa Falls (US-20): A 114-foot waterfall near Ashton, ID. Short paved trail leads to viewing platforms.
• Bear River Valley: Marshy wetlands near Montpelier, ID, ideal for birdwatching. The Bear River Migratory Bird Refuge is 30 miles off-route.
• Cache Valley: Mountain-ringed farmland with historic Mormon settlements. The American West Heritage Center in Wellsville shows pioneer life.

Local Commerce and Culture

Idaho Falls boasts the Idaho Falls Zoo and the Greenbelt along the Snake River. Logan, UT, features the historic Cache Valley courthouse and a thriving arts scene with galleries like the Nora Eccles Harrison Museum. Local businesses include farmer’s markets (seasonal) and cheese-makers like the Gossner Foods dairy in Logan.

In Heber City, the Heber Valley Railroad offers train rides, and the nearby Midway Ice Castles provide winter entertainment. Small towns like Driggs, ID, offer fly-fishing shops and local eateries with huckleberry-inspired cuisine.

Safety concerns include wildlife (deer, elk, moose) at dusk and dawn, especially near forested areas. I-15 through southeastern Idaho has long stretches with minimal services; carry water and snacks. Cell service is spotty between West Yellowstone and Ashton (20 miles with no signal).

• Rest areas: Idaho has 24 rest plazas along I-15; notable ones at milepost 190 (Monida) and 245 (Pocatello Creek). Utah’s I-15 has a rest area near Brigham City with picnic tables.
• Fatigue management: Break every 2 hours. Stretch at the lava flow viewpoint at Craters of the Moon National Monument (20 minutes off-route via US-26).
• Family stops: The Yellowstone Giant Screen Theater in West Yellowstone, the Bear River Migratory Bird Refuge, and the Logan Aquatics Center offer child-friendly breaks.

Pet-Friendly Framework

Most rest areas allow pets on leashes. National Forest lands (e.g., Gallatin, Targhee) welcome dogs on trails. In Heber City, dogs are allowed in parks but not inside restaurants. Check pet policies at hotels like the La Quinta in Idaho Falls.

Veterinary clinics exist in Idaho Falls (Animal Medical Center, 208-523-2133) and Logan. Carry extra water for your pet, especially in arid regions east of the Wasatch.

Hidden Off-Route Spots

Detour 10 miles to Kelly Canyon, ID, for hot springs (Kelly Warm Springs) accessible year-round. Near Montpelier, ID, visit the National Oregon/California Trail Center with interactive exhibits. In Utah, side-trip to Bear Lake (30 miles east of Logan) for turquoise water and raspberry shakes.

Another gem: The ghost town of Mercur, UT, near Tooele (45 min from Heber City), preserves gold-mining history.
