Winslow to Kemmerer Road Trip Guide: Route 66 to Fossil Country

At the corner of Kinsley and Second Street in Winslow, Arizona, a life-size bronze of a man with a suitcase stands forever waiting for a truck—a nod to the Eagles' hit 'Take It Easy.' That corner anchors your starting point, where Historic Route 66 still runs through downtown. Your destination, Kemmerer, Wyoming, sits 850 miles north, best known as the 'Fossil Fish Capital of the World'—the town's quarries have yielded perfectly preserved 50-million-year-old fish. The drive typically takes 13–14 hours of pure driving time, but plan for at least three days to absorb the landscapes and attractions along the way.

Long stretches between towns (up to 100 miles with no services) make planning essential. Carry extra water and blankets. Cell coverage is sporadic in Arizona and Utah—download offline maps in Flagstaff.

For families, the route abounds with kid-friendly attractions: the Moab Dinosaur Tracks (a short walk from the highway), the Frontier Fun Park in Kemmerer, and the hike to Horseshoe Bend near Page is 0.8 miles round-trip—stroller-friendly but shaded only in spots.

Pets are welcome at national parks' trails with leash rules; keep dogs on a 6-foot leash at all times. In Moab, many hotels allow pets for a $25 fee—check listings for specific policies.

Fatigue management is critical: stop every two hours or every 100 miles. Use the rest areas on I-70 in Utah, which boast scenic overlooks and picnic tables. The 'Rest Area at Mile 190' (westbound) offers bathrooms and vending machines.

From the Painted Desert's red-rock badlands near Holbrook to the Kaiparowits Plateau's striped cliffs, this drive is a geological sampler. The route passes through three distinct ecosystems: high desert, canyon country, and the Wyoming Basin's sagebrush steppe.

The landscape's aesthetics shift sharply with altitude: Winslow sits at 4,862 feet, while Kemmerer's elevation is 6,955 feet—pack layers for temperature swings. Summers can exceed 100°F in Page, while winter storms blanket the mountains in Wyoming.

Local commerce thrives in small towns like Mexican Hat, Utah, known for the iconic Mexican Hat rock and trading posts selling Navajo rugs and silver jewelry. In Moab, breweries and bike-shop cafés cater to adventure tourists, but many roadside gas stations double as craft stores, offering jerky, local honey, and artisan pottery.

The most efficient route follows I-40 West to Flagstaff, then US-89 North to Page, Arizona, cutting through the Navajo Nation. From Page, take US-89 to UT-95 and US-191 into Moab, Utah. Finally, I-70 East to US-191 North lands you in Kemmerer. This path avoids the congestion of Salt Lake City and offers the most direct access to national parks.

• Fuel Economics: Gas prices average $3.50/gal in Arizona, $3.70 in Utah, and $3.20 in Wyoming. A 25-mpg vehicle will cost roughly $119 in fuel. Fill up in larger towns like Flagstaff and Moab to avoid high prices at remote stations.
• Road Quality: I-40 is well-maintained, but US-89 and UT-95 are two-lane highways with occasional potholes near construction zones; watch for wildlife at dawn and dusk.
• UNESCO Sites: Though no UNESCO World Heritage Sites lie directly on the route, Mesa Verde National Park (a 2-hour detour from Cortez, CO) and Grand Canyon National Park (a 1.5-hour detour from Williams) are nearby—both are designated sites.
