Torrey to Spearfish Road Trip: Essential Guide

This route crosses three states—Utah, Colorado, and Wyoming—covering approximately 650 miles (1,046 km) of high desert, mountain passes, and rolling plains. The driving time without stops is roughly 10 to 11 hours, but the journey demands at least two days to fully absorb its wonders.

At the midpoint, near Rawlins, Wyoming, the Continental Divide splits the watersheds. The section from Torrey to Salina (UT-24 east) is a two-lane highway carved through ancient rock, where pronghorn antelope often outnumber cars.

When planning, consider how to find the best stops and hidden gems between cities to elevate your experience beyond the major attractions.

Weather can change rapidly in Wyoming; summer thunderstorms cause flash floods in low-water crossings, and winter blizzards can close I-80 for hours. Check road conditions on Wyoming 511. Always carry water, food, and blankets.

• Rest areas: Major rest stops at mile markers 142 (Cedar City side) on I-70 eastbound, near Rock Springs on I-80 (mm 104), and at Rawlins (mm 214).
• Fatigue management: Break the drive into three equal segments of 3–3.5 hours each. Ideal stops are Green River, UT (for lunch), Rawlins, WY (fuel and stretch), and Lusk, WY (overnight stay).
• Family suitability: Kid-friendly stops include the Flaming Gorge Dam visitor center (educational video and fish viewing), and the Lusk to Spearfish segment features the Black Hills Petrified Forest (a private attraction with fossilized trees).
• Pet-friendly framework: Most rest stops have designated pet areas. Hotels in Rawlins and Lusk accept pets; check policies in advance. National Forest lands along the route allow free camping with leashed pets.

Hidden Off-Route Gems

• About 30 minutes north of I-80 near Wamsutter, the Killpecker Sand Dunes are the largest active dunes in Wyoming (accessible by dirt road).
• Near Lusk, the La Prele Path (a short hike) reveals paleo-Indian carvings dating back 10,000 years.
• In South Dakota, before Spearfish, look for the Spearfish Canyon Scenic Byway (US-14A) which offers 20 miles of limestone cliffs and Bridal Veil Falls.

Culinary infrastructure: Green River has Hermosa Market (best Mexican food in the region). Rawlins offers the Wagon Wheel (classic Wyoming diner with steaks). Near Lusk, the Stoplight Store & Deli serves homemade pasties. In Spearfish, the Bay Leaf Café provides farm-to-table cuisine.

From Torrey, the drive passes through Capitol Reef National Park’s orange cliffs and the San Rafael Swell. US-24 east offers views of Goblin Valley State Park (detour required) and the Green River.

• Flaming Gorge National Recreation Area (mile 150) features red sandstone canyons and a massive reservoir. Stop at the Flaming Gorge Dam visitor center.
• In Wyoming, the landscape shifts to the Great Divide Basin: sagebrush steppe and antelope herds. The Red Desert near Wamsutter offers solitude and, in spring, wildflower blooms.
• Near Lusk, the terrain becomes rolling hills with ponderosa pines, heralding the Black Hills. US-85 enters South Dakota past the Running Water Creek canyon.
• Local commerce: In Green River, Robbers Roost Trading Post sells handcrafted Navajo jewelry. Rawlins features the Wyoming Frontier Prison Museum (offering tours of the historic penitentiary).

UNESCO World Heritage Sites: This route does not directly pass any UNESCO sites, but nearby Dinosaur National Monument (100 miles north of Rock Springs) holds a UNESCO World Heritage fossil quarry (part of the Jurassic Morrison Formation). A worthwhile detour if time allows.

The primary route follows US-24 east from Torrey to I-70 in Utah, then I-70 east to I-15 north at Cove Fort (a confusing interchange—watch signs closely). Continue on I-15 north to I-80 east through Wyoming, then US-85 north and US-14 east into Spearfish.

• Fuel stops are sparse between Green River, UT and Rock Springs, WY (about 80 miles). Fill up in Green River.
• In Wyoming, fuel stations cluster at Rawlins, Laramie, and Lusk. Between Rawlins and Lusk, it is 130 miles with limited services.
• Cell service is unreliable across much of Wyoming. Download offline maps for navigation.
• Road quality: Excellent on Interstates (I-70, I-80). Two-lane sections (US-24 in Utah and US-85 in Wyoming) are well-maintained but narrow in places.
