Driggs ID to Valentine NE: Epic Great Plains Road Trip

This route from Driggs, Idaho to Valentine, Nebraska crosses the Continental Divide at Teton Pass (US-22, elevation 8,431 ft) and descends into the heart of the Great Plains. It takes approximately 17 hours of driving time without stops, covering 1,100 miles across Idaho, Wyoming, Nebraska, and a corner of South Dakota.

One specific detail: just west of Valentine you'll cross the Niobrara River, which flows east through a scenic canyon system designated a National Scenic River. The river's name means 'running water' in Ponca, and the area is known for its fossil-rich bluffs.

This is not a drive you'll want to rush. As the blog how to find the best stops and hidden gems between cities explains, the best experiences lie off the main drag.

The main thread is US-26 east from Driggs to Casper, WY, then US-20/US-26 east to Ogallala, NE, and US-83 north to Valentine. Pay attention: Wyoming's US-26 between Riverton and Casper is notorious for limited services and severe winter closures.

Fuel and Route Economics

• Average gasoline cost: ~$3.80/gal; expect higher prices in small Wyoming towns like Shoshoni and Douglas.
• Total fuel cost for a 20 mpg vehicle: ~$209.
• Fuel stops are reliable every 50-70 miles on main highways, but between Lusk, WY and Valentine, NE you'll go 170 miles with only one gas station (at Lusk). Fill up in Lusk.

Climatic Conditions & Route Aesthetics

• Summer: 80-95°F, isolated thunderstorms possible in the afternoon across Nebraska sandhills.
• Winter: Frequent closures on Teton Pass (US-22) and US-26 in Wyoming; blizzard conditions common January-February. Use the Wyoming 511 app.
• Spring/Fall: Pleasant but unpredictable; watch for road sand in spring and snow flurries in late October.

Infrastructure Safety & Road Quality

• Interstates (I-25 and I-80) are in excellent condition; two-lane US highways (US-26, US-20, US-83) vary from good to patchy.
• Watch for wildlife: pronghorn, deer, and an occasional moose near the Wyoming-Idaho border.
• Cell service is spotty from Shoshoni, WY to Oshkosh, NE; download offline maps in advance.

Family and Child Suitability

• Carry snacks for dry stretches; the Wyoming towns of Jeffrey City and Lost Cabin have no stores.
• Plan for bathroom breaks: rest areas are spaced about every 1.5 hours on I-80; on US-83, the only public restroom between Merriman, NE and Valentine is at the Highway 83 Visitor Center.
• For kids: the Wind River Dinosaur Center in Thermopolis offers fossil dig experiences.

Pet-Friendly Framework

• National forests (Bridger-Teton, Medicine Bow) allow dogs on trails; the Niobrara National Scenic River has limited pet-friendly campsites.
• Motels: Most Super 8 and Budget Inn locations along US-26 accept pets with a modest fee ($10-20).
• Build in a 15-minute stop every 2 hours at a rural pullout—there are many crossroads where your dog can stretch legs safely away from traffic.

Fatigue Management & Rest Zones

• Safe places to nap: rest areas on I-80 near Sinclair, WY (mile 129) and Ogallala, NE (mile 126) are clean and well-lit. Avoid overnight parking at remote highway pullouts due to wildlife.
• Take a short walk at the Fort Laramie National Historic Site (on US-26 near Torrington, WY) to break up driving.

Hidden Off-Route Spots

• On US-20 east of Casper, turn north on WY-487 to visit the Sweetwater Station, a former Pony Express stop with remnants of a stone stable.
• Near Ellsinore, WY, the 'Lost Springs' area has a concrete water tank built by Chinese laborers in the 1860s.
• In Nebraska, Bridgeport State Park has unusual rock formations called 'Courthouse and Jail Rocks'—a pioneer navigational landmark.

Culinary Infrastructure

• Must-eat: The Baked Potato (Jackson, WY) is famous for potato skins and elk burgers; in Ogallala, the Canteen Drive-In serves hand-breaded chicken-fried steak.
• Vegetarian options are sparse in the Great Plains; pack a cooler with fresh produce from grocery stores in Rock Springs, WY.
• Local bakeries: The Cowboy Store in Lusk (homemade cinnamon rolls) and the Rustic Cafe in Valentine (pasties and rhubarb pie).

Natural Landscapes & Attractions

From the Tetons to the Nebraska Sandhills, this drive is a continuous geological storyboard. The Teton Range rises abruptly from the valley floor near Driggs; 20 miles south of Jackson, the National Elk Refuge hosts the largest elk herd in North America.

• Wind River Canyon (WY): US-20 carves through a narrow marble and limestone canyon just south of Thermopolis; pull over at the viewing area for bighorn sheep sightings.
• Pathfinder Reservoir (WY): A Bureau of Reclamation lake on the North Platte River, popular for windsurfing and bald eagle nesting.
• Sandhills Scenic Byway: From Alliance, NE north on NE-61 to Valentine, the road rolls through grass-covered dunes—the largest sand dune formation in the Western Hemisphere.

UNESCO World Heritage Sites

• The only UNESCO site near the route is the Wapusk National Park (no), but consider a side trip to Yellowstone National Park (UNESCO, 90 miles north of Dubois, WY). Alternatively, you can branch off for the Chief Joseph Scenic Highway (WY-120) to the Sunlight Basin, a geological wonder.

Local Commerce & Culture

Driggs has a lively farmers market on Saturdays (June-Sept). In Thermopolis, the Hot Springs State Park offers free public baths in naturally heated mineral water. Valentine's annual Cherry County Fair in August features rodeo, demolition derby, and a pioneer parade.

Small towns like Lusk (population 1,500) are gateways to the Spanish Diggings, ancient Native American quarry sites. In Oshkosh, the Garden County Historical Museum displays pioneer artifacts from the late 1800s.
