Idaho Falls to Oakhurst Road Trip: Ultimate Guide

The drive from Idaho Falls to Oakhurst covers roughly 780 miles across Idaho, Utah, Nevada, and California. US-20 west from Idaho Falls joins I-15 south near Dubois, then I-80 west across Utah and Nevada. Near Fernley, US-50 west (Loneliest Road) merges to CA-41 south into Oakhurst. The route passes the Great Salt Lake, the Bonneville Salt Flats, and the Sierra Nevada foothills.

A historical quirk: the stretch of US-50 in Nevada was part of the Pony Express trail. Today, it's known for its desolate beauty and small towns like Eureka. The entire drive takes about 12 hours of pure driving, but plan for 2-3 days to enjoy stops.

Fuel stations are sparse in central Nevada. Fill up in Salt Lake City, Wendover, and Ely. Gas prices are lower in Idaho and Utah than in California. Trucks are common on I-80; watch for truck stops with diesel and food.

• Rough cost: $120-$160 in gas (depending on vehicle)
• Rest stops: Every 50-100 miles on interstates; some have restrooms and vending machines
• Road tolls: none on this route

For fatigue management, the Nevada desert can induce drowsiness. Plan stops every 2-3 hours. Recommended rest stops: Bonneville Salt Flats rest area (milepost 4 on I-80) and Cathedral Gorge State Park near Panaca.

• Longest stretch without services: ~100 miles between Ely and Eureka, NV
• Accommodations: mid-range motels in major towns; book ahead in peak season

Natural landscapes vary from the Snake River Plain to the Great Basin desert and Sierra Nevada forests. In Idaho, the lava fields near Arco are stark and ancient. The Great Salt Lake in Utah is a massive inland sea with unique brine shrimp and algae. The Bonneville Salt Flats in Nevada offer a blinding white expanse, often used for land speed records.

• Best landscapes: Craters of the Moon (Idaho), Bonneville Salt Flats (Utah/Nevada), Great Basin National Park (Nevada)
• Hidden gem: Hickison Petroglyph Recreation Area near Austin, NV – ancient rock art off US-50
• Tip: carry sunglasses and sunscreen for the reflective salt flats

Local commerce along the route includes small-town diners and souvenir shops. In Ely, the Nevada Northern Railway Museum offers train rides. In Oakhurst, local shops sell Sierra Nevada arts and crafts. The route also passes through mining towns like Eureka, known for its historic opera house.

• Local food: fry sauce in Idaho, funeral potatoes in Utah, Basque cuisine in Nevada

UNESCO World Heritage Sites: While none are directly on the route, two are nearby: Yellowstone National Park (north of Idaho Falls) and Yosemite National Park (west of Oakhurst, ~1 hour). Consider detours for these iconic parks.

• Yellowstone: 2.5h north of Idaho Falls
• Yosemite: 1h west of Oakhurst via CA-41
• Both require entrance fees; plan ahead in summer

Road quality is excellent on interstates, but US-50 in Nevada has some rough patches. Watch for wildlife, especially deer and antelope at dawn/dusk. In winter (Nov-Mar), sections near the Sierra Nevada may require chains. Check weather forecasts.

• Emergency services: dial 911; cell coverage limited in Nevada
• Roadside assistance: AAA or towing companies in major towns
• Winter driving: carry chains, blankets, and extra water

Family and child suitability is high. The route offers many kid-friendly stops: the Living Planet Aquarium in Salt Lake City, or the Bonneville Speedway Museum. Plan for bathroom breaks every 2-3 hours. Pet-friendly framework: most motels accept pets, and rest areas allow leashed animals. In Nevada, the dry heat requires carrying extra water for pets.

• Family stops: Discovery Gateway Children's Museum (SLC), Ely Railroad Museum
• Pet-friendly hotels: Motel 6, La Quinta, and many independent motels
• Pet care: pack dog waste bags and a collapsible bowl

Climatic conditions vary: Idaho Falls has cold winters and mild summers; Nevada desert has extreme cold at night and heat in day; Oakhurst has Mediterranean climate. The best driving months are May-June and September-October, avoiding summer heat and winter snow. Spring brings wildflowers in the Great Basin.

• Rain: infrequent; dry most of the year
• Elevation: passes over 7,000 ft in the Sierra Nevada; beware of altitude sickness

Culinary infrastructure: fast food chains near exits in urban areas, but rural Nevada has limited options. Pack snacks and water. Hidden off-route spots: the ghost town of Hamilton, NV, near Ely (off US-50) or the Lehman Caves at Great Basin National Park. Both require short detours but offer unique experiences.

• Ghost town Hamilton: accessible by dirt road, 4WD recommended
• Lehman Caves: guided tours $15, beautiful limestone formations
• Other hidden gems: the Ward Charcoal Ovens near Ely, or the Toiyabe National Forest
