Winslow to Thermopolis: Route Guide

The 760-mile route from Winslow, Arizona, to Thermopolis, Wyoming, begins in the high desert at 4,880 feet and ends near the Big Horn Hot Springs at 4,500 feet. It traverses the Colorado Plateau, crosses the Continental Divide at two points, and passes through the Uinta Mountains. The journey takes about 11 hours of pure driving, but with stops for meals, fuel, and sightseeing, plan for 14–16 hours. Key highways are I-40 east, US-491 north, US-191 north, and I-80 west.

The route passes through four distinct ecosystems: Painted Desert, Colorado Plateau, San Juan Basin, and the Wyoming Basin. Near Winslow, the Painted Desert offers vivid red and orange badlands. Further north, the Uinta Mountains rise to 13,528 feet at Kings Peak, the highest in Utah. Wyoming's Wind River Canyon, just south of Thermopolis, cuts through ancient granite and limestone, offering roadside geology displays.

Local commerce thrives on tourism and resource extraction. In Gallup, Navajo artisans sell jewelry at the historic downtown plaza. Blanding, Utah, is a gateway to the Bears Ears National Monument. Thermopolis's economy revolves around hot springs and ranching. For authentic dining, try local diners in Cortez or Vernal for Mexican and Western fare.

UNESCO World Heritage Sites are within a two-hour detour: Mesa Verde National Park (near Cortez, CO) and the Taos Pueblo (south of the route). Chaco Culture National Historical Park, another UNESCO site, lies 90 miles east of Gallup.

Fuel stops are abundant along interstates but sparse on rural segments like US-491 and US-191 between Shiprock and Vernal. Plan to fill up at Gallup, Farmington, Cortez, or Blanding, and carry extra water. Gas prices are typically 10-15% lower in New Mexico than in Utah or Wyoming. Lodging options are limited in small towns; book ahead in Vernal or Rock Springs if needed. For real-time road conditions, call 511 in Arizona, New Mexico, Utah, and Wyoming.

• Average fuel cost for the trip: $85-100 for a mid-size sedan.
• Cell coverage: reliable in towns, spotty in rural stretches.
• No tolls on this route.
• Recommended rest stops: Gallup Visitor Center, Cortez Cultural Center, Dinosaur National Monument.

Road quality is generally good on interstates and major US highways, but expect mountain sections with steep grades and wildlife crossings, especially between Vernal and Rock Springs. In winter, snow and ice are common; carry chains. For rest breaks, designated rest areas are spaced every 50-100 miles. To manage fatigue, stop every 2 hours and use the how to find the best stops and hidden gems between cities guide.

Child-friendly stops include the Discovery Center in Winslow, the Sherman Alexie exhibit in Spokane (off-route), and the Hot Springs State Park in Thermopolis, which has a splash pad and dinosaur statue. The route is pet-friendly, but keep dogs on leashes; many hotels, like Best Western in Vernal and Super 8 in Rock Springs, allow pets for a fee. Hidden gems: Four Corners Monument (17 miles west of Shiprock, briefly off-route), and the Canyon Pintado National Historic District near Rangely, Colorado.
