Ely to West Yellowstone: Epic Nevada-Montana Road Trip Guide

The drive from Ely, Nevada to West Yellowstone, Montana covers about 420 miles along US-93, US-20, and US-191. This route passes through the remote landscapes of the Great Basin and the volcanic wonders of eastern Idaho.

One little-known fact: the section from Arco, Idaho to West Yellowstone follows the path of a massive prehistoric supervolcano eruption, and you can see evidence in the dark basalt cliffs near Craters of the Moon. The drive takes roughly 7–8 hours without stops, but allow two days for a comfortable trip exploring side attractions.

Road conditions are generally good on US highways. However, winter weather can cause closures or require chains, especially over Monida Pass (elevation 6820 ft) on the Montana border. Check local advisories at how to find the best stops and hidden gems between cities.

Accommodation options are limited along the route. Consider staying overnight in Twin Falls or Idaho Falls to break the drive. For those seeking a unique stay, the town of Arco has the historic Motel 66, while West Yellowstone offers countless lodges near the park entrance.

The landscape transitions dramatically from the high desert of Nevada to the volcanic plains of Idaho and finally the forested mountains of Montana. South of Twin Falls, you'll cross the Snake River Canyon, where the Perrine Bridge offers views of the 486-foot-deep gorge.

• Great Basin National Park (near Ely): Ancient bristlecone pines and Lehman Caves
• Craters of the Moon National Monument (near Arco): Vast lava fields and cinder cones
• Mesa Falls (north of Ashton): Scenic waterfall on the Henrys Fork of the Snake River
• West Yellowstone: Gateway to Yellowstone National Park's geysers and wildlife

Local commerce along the route is small-scale. In Idaho, potato farms and Basque culture dominate; in Nevada, mining and ranching are key. Don't miss the Basque restaurant in Twin Falls or the local craft beer scene in Idaho Falls. For souvenirs, the town of West Yellowstone has numerous shops selling Native American crafts and Yellowstone-themed items.

Safety on this route is generally high, but be aware of wildlife crossings, especially at dawn and dusk. Deer, elk, and even moose can appear suddenly. Also, be prepared for long stretches without cell service, particularly between Ely and Jackpot.

• Speed limits: 70-80 mph on interstates, slower on two-lane highways
• Rest areas: Major rest stops at Wells and Twin Falls, plus numerous scenic overlooks
• Emergency services: Limited; nearest hospitals in Elko, Twin Falls, and Idaho Falls

For families, the route offers engaging stops. Kids will love the Lava Flow Campground at Craters of the Moon, where you can walk on the lava. The EBR-1 Atomic Museum near Arco (first nuclear power plant) is educational. In West Yellowstone, the Grizzly and Wolf Discovery Center is a hit.

Pet-friendly options: Most hotels along the route accept pets, but confirm in advance. There are many BLM lands where you can let your dog run, but inside national parks, dogs must be leashed and are restricted on trails.

Fatigue management is crucial. The mind-numbing monotony of Nevada's straight highways can cause drowsiness. Plan to stop every two hours at interesting spots like the Shoshone Falls in Twin Falls or the lava tubes at Craters of the Moon. For hidden off-route spots, consider the City of Rocks National Reserve (southeast of Burley) or the ghost town of Big Springs (near Arco).
