Park City to Show Low: Epic Road Trip Guide

This route traces a segment of the Old Spanish Trail, a 19th-century trade route connecting Santa Fe to California. The section from Park City to Show Low traverses the Colorado Plateau's edge, crossing the Green River at a point where John Wesley Powell's 1869 expedition nearly capsized. The drive covers approximately 430 miles via US-191 and US-160, taking roughly 7 hours without stops. The highway numbers change at Moab, where US-191 becomes the main artery through Navajo Nation lands. A peculiar local quirk: near Bluff, UT, you'll encounter a 20-mile stretch with no services—a remnant of the Mormon pioneer's 'Hole-in-the-Rock' expedition.

The route descends from Wasatch Range alpine forests through the slickrock deserts of Moab, then into the high desert of the Navajo Nation. The San Rafael Swell (mile 50-80) is a geological anticline with striped sandstone cliffs. Arches National Park is just off US-191, but its crowds can be bypassed via the scenic Potash Road (UT-279) along the Colorado River. At Mexican Hat rock formation (mile 200), the landscape shifts to the Monument Valley Navajo Tribal Park. Here, local vendors sell silver jewelry and fry bread at roadside stands.

• Moab breweries: Moab Brewery (traditional pub fare) and Dewey's Grill (river views).
• Bluff, UT: Fort Bluff trading post sells Navajo rugs and pottery.
• Show Low's White Mountain Apache culture: Hon-Dah Casino operates a gift shop with authentic crafts.

US-191 south of Bluff is a two-lane road with occasional cattle crossings. Wildlife (mule deer, elk) are active at dawn/dusk. Speed limits drop to 35 mph through small Navajo towns like Church Rock. For families, the edge of the Manti-La Sal National Forest near Monticello offers easy nature trails. The Goosenecks State Park viewpoint (UT-261) is a safe, fenced overlook of the San Juan River's 500-foot deep meanders. Pet-friendly motels: the Rodeway Inn Blanding accepts dogs, and the Super 8 Moab has pet rooms.

• Rest zones: Rest area at I-70/US-191 junction (mile 0), BLM campsite at Newspaper Rock (mile 90).
• Fatigue management: The stretch between Blanding and Kayenta (85 miles) has no services; stop at the Four Corners Monument (optional, $5 entrance).
• Emergency services: Bluff has a clinic (call 435-672-2200), Moab has a hospital. Cell coverage: best on ridges, none in valleys.

US-191 from I-70 south is a well-maintained two-lane highway with moderate traffic. Gas stations are sparse between Green River, UT (mile 25) and Blanding, UT (mile 145). Plan to fill up at the Shell in Green River (38.993°N, 110.162°W). Diesel is available at most stations, but electric vehicle charging is limited to Moab and Blanding. Cellular coverage drops significantly south of the San Rafael Swell. Download offline maps offline. For those seeking detours, the how to find the best stops and hidden gems between cities approach works well here: explore side roads like UT-95 to Natural Bridges.

• Recommended fuel stops: Green River, UT (Shell), Blanding, UT (Chevron), Kayenta, AZ (Plaza).
• Tire pressure check: altitudinal changes from 7,000 ft in Park City to 4,000 ft in Moab can affect tire PSI.
• Winter conditions: I-70 and US-191 may require chains from Oct-April; check UDOT alerts.
