Green River, UT to Athol, ID: An Epic Western Road Trip Guide

This route crosses five states and two distinct climatic zones, starting in the red-rock desert of Utah and ending in the evergreen forests of northern Idaho. It covers about 800 miles (1,287 km) and, without stops, takes roughly 12 hours of driving, but you'll want to allocate at least three days to properly savor the experience.

The most significant UNESCO site near the route is the Mesa Verde National Park in Colorado, but it requires a significant detour.

Local commerce thrives in towns like Helper, Utah, known for its antique shops, and in McCall, Idaho, a resort town with boutique stores.
