Fuel economy is critical on this route, especially in rural sections where gas stations can be 50+ miles apart. Fill up in Albuquerque, Santa Fe, Alamosa, and Denver.

• Infrastructure safety: Rest stops are available every 30-60 miles on interstates; less frequent on US highways. Cell service is spotty in the San Luis Valley and Wyoming plains.

After crossing into Colorado, the road skirts the Great Sand Dunes National Park before reaching Alamosa. From Alamosa, continue north on US-285 through the Rio Grande National Forest, passing Monte Vista and Saguache. The route climbs over Poncha Pass into Salida, then follows US-285 north to Fairplay and over Kenosha Pass into Denver. From Denver, I-25 north to Casper, then US-20/US-26 west to Thermopolis.

The landscapes on this drive are staggeringly diverse. You start in the high desert of New Mexico, with piñon-juniper forests and red sandstone cliffs.

Road safety is paramount. The most dangerous sections are the two-lane highways through mountain passes: La Bajada (NM), Poncha Pass (CO), and Kenosha Pass (CO) can have ice and fog in winter.
