Valentine NE to Evanston WY: Drive Guide & Top Stops

Before the transcontinental railroad, the route now followed by US-20 and I-80 was a corridor for the Oregon Trail. The Nebraska segment near Valentine crosses the Sandhills, the largest stabilized dune field in the Western Hemisphere, covering about 20,000 square miles.

The route crosses the Continental Divide at three points: South Pass (elevation 7,412 ft) and two unnamed saddles in Wyoming. The highest sustained elevation is along I-80 between Laramie and Rawlins, averaging 7,000 ft. Pack for rapid weather shifts: summer storms drop hail, and winter blizzards can close highways for hours.

Most travelers use US-20 west to Casper, then I-80 southwest to Evanston. The direct route (US-20 to US-26 to I-80) covers 630 miles; accounting for fuel and rest stops, plan for 11–12 hours. The best stops Valentine, NE to Evanston, WY are spaced remarkably evenly: every 60–80 miles a town offers fuel and food.

• Fuel costs run around 10% cheaper in Wyoming than in Nebraska due to state tax differences.
• Diesel is widely available at truck stops; gasoline stations become sparse west of Casper on I-80.
• Road quality is excellent; US-20 is a two-lane highway with some passing lanes, while I-80 is a four-lane interstate with a 75 mph speed limit.

Plan fuel stops at: Valentine, NE; Chadron, NE; Lusk, WY; Casper, WY; Rawlins, WY; and Rock Springs, WY. These towns have 24-hour fuel and convenience stores. Carry extra water and blankets in winter.

For families, the route includes the National Museum of Military Vehicles in Dubois, WY (open 2023), but it's a detour. The Fort Caspar Museum in Casper offers a hands-on frontier experience for kids. For a quick break, the Laramie High Plains Arboretum has easy walking trails.

Pet-friendly stops: many motels in this corridor accept dogs, notably in Lusk and Evanston. The veterinary clinic in Valentine is small; larger facilities are in Scottsbluff, NE. Restrooms with pet areas are scarce; bring poop bags and use rest stops.

To manage fatigue, use the rest areas at Burns, WY (mile 77) and Sinclair, WY (mile 216) – they have picnic tables and clean restrooms. The Wyoming Highway Patrol operates a weigh station at Wamsutter that also offers a safe overnight parking area. The 700,000-acre Thunder Basin National Grassland near Douglas is a remote expanse where you can stop and hear only wind and birds.

Valentine's main attraction is the Niobrara River, a National Scenic River with 100-foot-tall waterfalls at Smith Falls State Park. The northern Sandhills bloom with prairie wildflowers in June, such as purple coneflower and blanketflower.

Eastern Wyoming's high plains are punctuated by the Missouri Buttes and Devils Tower, the latter a National Monument and the first declared in the U.S. (1906). Devil's Tower is 70 miles north of I-80 near Sundance; a detour adds two hours.

Local commerce reflects its ranching heritage: Western wear stores, stockyards, and small-town diners serve chicken-fried steak and fry bread. Visit Fort Robinson State Park (near Crawford) for the historic cavalry post and Cheyenne Outbreak of 1879. The park offers lodging in former officers' quarters.
