Las Vegas to Riverton Road Trip: Desert to Rockies Guide

On US-93 north of Las Vegas, the asphalt cuts through the Mojave like a black scar. At mile marker 45, you’ll cross the 36th parallel—the same latitude as the ancient Bristlecone pines in Great Basin National Park. This 670-mile journey traces the edge of the Basin and Range Province, where the Earth’s crust stretches thin, creating the stark basins and abrupt mountain ranges that define the drive from Las Vegas, NV to Riverton, WY. The route is a lesson in aridity and altitude, starting at 2,000 feet and climbing to over 7,000 feet at South Pass.

The drive takes 10–12 hours without stops, but you’ll want to stretch it over two days. The best stops between Las Vegas and Riverton are found along US-93 and I-15, then US-287 through Wyoming. This is not a route for the impatient; it rewards those who pause to read the geological billboards—the tilted strata of the Mormon Mountains, the red-rock canyons of Utah, the fossil-laced Green River Formation. For context, a century ago this corridor was a stagecoach trail; today it’s a tarmac ribbon connecting two disparate worlds: the neon desert and the high-plains frontier.

To maximize your trip, consider how to find the best stops and hidden gems between cities. The route offers everything from ancient petroglyphs to dinosaur quarries. This guide unpacks the logistics, landscapes, and local secrets that make this drive worth every mile.

Most of the route is two-lane highway, especially US-93 in Nevada and US-287 in Wyoming. Passing zones are rare; be patient with slow vehicles. Wildlife crossings are common: mule deer and pronghorn antelope graze near the road, especially at dawn and dusk. In Wyoming, cattle guards and open range mean livestock can appear suddenly. Safe passing zones are marked with dashed yellow lines, but don't assume oncoming drivers see you—many sections have rolling hills that limit visibility.

• Rest stops: Caliente (NV) has a small rest area; Ely offers a full service plaza; Farson (WY) has a general store; Riverton has multiple hotels
• Family stops: Cathedral Gorge (hiking, picnicking); Great Basin NP (cave tours, stargazing); Fossil Butte NM (junior ranger program)
• Pet-friendly: Most national forests and BLM land allow dogs on leash; Lehman Caves does not permit pets; Farson Mercantile has a pet-friendly patio
• Fatigue management: Plan to stop every 2 hours; the scenery is monotonous in places; podcasts or audiobooks help

If you have kids, the route is rich with educational stops. At the Utah Field House of Natural History in Vernal, they can touch dinosaur bones. In Wyoming, the Killpecker Sand Dunes (near Farson) are a natural playground—the largest active sand dune field in North America. For pet owners, the BLM campgrounds at Cathedral Gorge and Great Basin are pet-friendly. Always carry extra water for your dog, as summer temperatures in Nevada can exceed 100°F.

Night driving is inadvisable on US-93 due to wildlife and limited lighting. If you must travel after dark, use high beams where legal. The darkest skies in the Lower 48 lie between Caliente and Ely; stop at the side of the road (pull completely off) to see the Milky Way. Fatigue can creep up on the long, straight stretches. Alternatives: break the drive in Ely (mi 270) or Rock Springs (mi 570). Both have chain hotels and local motels. The Overnight in Ely: the historic Hotel Nevada, built in 1929, offers vintage charm and a ground-floor casino.

The primary highway is US-93 from Las Vegas to I-15 near Crystal Springs, then I-15 north to Salt Lake City. From there, take I-80 east to Lyman, Wyoming, then US-191 north to US-287 through the Green River Basin. The final leg follows US-287 into Riverton. Expect long stretches without services, especially between Alamo and Caliente, NV—a 100-mile gap with one gas station at Ash Springs.

• Total distance: 670 miles (1,078 km)
• Estimated driving time: 10–12 hours (without stops)
• Recommended fuel stops: Caliente, NV (mi 100); Ely, NV (mi 270); Delta, UT (mi 380); Rock Springs, WY (mi 570)
• Road surface: Mostly good asphalt with occasional rough patches in NV on US-93; I-15 and I-80 are excellent
• Cell coverage: Patchy on US-93 between Las Vegas and Ely; strong on interstates; limited in Wyoming between Lyman and Farson

Fuel economy matters here: a full tank from Las Vegas won't reach Ely. Fill up in Alamo (mi 80) or Caliente (mi 100). In Nevada, gas is cheapest in Las Vegas; prices rise by 20–30 cents in rural stations. Wyoming offers lower fuel taxes, so fill up there before heading into the Wind River country. If you're wondering is it worth driving Las Vegas to Riverton, the solitude and geological wonders make it a clear yes.

The first 200 miles reveal the Basin and Range: valley floors of saltbush and creosote, mountains of limestone and quartzite. At Cathedral Gorge State Park (mi 180, just off US-93 in Nevada), walk among slot canyons carved into bentonite clay. The park’s “cathedral” spires are remnants of an ancient lakebed, layered with volcanic ash. Further north, Great Basin National Park (near Ely) holds Lehman Caves, a marble wonderland of stalactites and rare shield formations. The park’s 13,063-foot Wheeler Peak supports the oldest living organisms on Earth—bristlecone pines that have stood for 4,800 years.

Crossing into Utah, the landscape shifts to red sandstone and juniper-sage steppe. The town of Delta (mi 380) is a gateway to the Topaz Mountain gem fields, where you can dig for sunstones and topaz. But the real gem is the Cleveland-Lloyd Dinosaur Quarry (near Price, UT), a Jurassic bone bed containing over 12,000 fossils from Allosaurus and other predators. This site is a UNESCO World Heritage candidate within the Jurassic National Monument. The fossils are so dense that paleontologists have recovered 46 individual Allosaurus skeletons.

In Wyoming, the Green River Basin unfolds as a high-desert steppe at 6,000–7,000 feet. The town of Farson (mi 550) is famous for its enormous ice cream cones at the Farson Mercantile—a local commerce icon. The Wind River Range looms to the north, its glaciated peaks resembling the Alps. Riverton sits at the confluence of the Wind River and Little Wind River, cradled by the Wind River Indian Reservation. The reservation’s history is palpable; the Eastern Shoshone and Northern Arapaho have lived here since the 1878 agreement. Visit the Wind River Heritage Center to understand the cultural depth.
