Panguitch to Salmon: Utah to Idaho Road Trip Guide

This route begins at 6,600 feet in Panguitch, Utah, passes through the geologically young volcanic fields of the Great Basin, and ends at the Salmon River in central Idaho. The drive covers roughly 400 miles and typically takes 7 hours without stops.

You'll cross the Utah-Idaho border at the town of Malad City, passing through the Bear Lake Valley. The highway numbers change from US-89 to I-15/US-20/US-93.

Fuel costs are usually lower than the national average in Utah and Idaho. Plan to fill up in Beaver or Tremonton, as stretches between towns can be 80 miles or more. Total fuel cost for a sedan is roughly $35–$45 based on $3.50 per gallon.

Road conditions are generally good: I-15 is a modern interstate; US-93 from Twin Falls to Salmon is a two-lane highway with passing lanes and smooth pavement. Winter storms can cause closures on US-93 north of Challis; check weather before departing.

You'll pass near the Mormon Row Historic District in Jackson, Wyoming, a nationally registered place with early 20th-century log cabins.

Road safety: Wildlife crossings are frequent on US-93 between Challis and Salmon; stay alert for deer and elk at dusk. Speed limits on two-lane roads are 65 mph, but reduce to 55 on curved sections. Use low gear on long downgrades, such as the descent into Arco Valley from the north on US-93.

Family suitability: Many stops are kid-friendly, including the Lava Hot Springs pool (has a zero-depth entry) and the Salmon River. The National Oregon/California Trail Center in Montpelier is a well-known interactive museum with a wagon ride and gold panning.

Pet-friendly: Yellowstone and Grand Teton National Parks allow leashed pets on trails, but much of the geothermal areas are off-limits. In Logan, check out the Aggie Ice Cream – a tradition since 1914 – where outdoor tables are pet-friendly.

Fatigue management: Plan stops every 2 hours. Rest areas at Tremonton and Arco (near the reactor) have restrooms and picnic tables. A 20-minute stop at the Idaho Potato Museum in Blackfoot offers a chance to stretch and learn about the state's staple.

Famous geological feature: Craters of the Moon National Monument and Preserve, a 750,000-acre volcanic landscape with lava tubes and cinder cones, lies 60 miles west of Teton Valley.

UNESCO World Heritage Sites: none directly on the route, but Yellowstone National Park (part of the Greater Yellowstone UNESCO site) is a 100-mile detour from Idaho Falls. The park's thermal features like Old Faithful are 2 hours from the highway.

Local commerce: In Panguitch, browse the historic Main Street with quilts hanging from buildings in the summer. In Salmon, visit Sacajawea Interpretive Center, open daily from June to September, to learn about the Lemhi Shoshone.

Best stops between Panguitch, UT and Salmon, ID include the Bear Lake State Park (both sides), where you can drive the east side and see turquoise water – a car-killing beauty. For hidden off-route spots, turn at Lava Hot Springs, Idaho, 30 minutes from the highway, to soak in natural mineral pools at 112°F.

how to find the best stops and hidden gems between cities is useful for discovering less-touristed gems like the Minnetonka Cave in St. Charles Canyon, a 5-mile detour.
