Winslow is a Route 66 town in northern Arizona, east of Flagstaff and close to the edge of Hopi country. It is famous for one line in an Eagles song, but the better reason to stop is the mix behind the photo: Santa Fe Railway history, Fred Harvey architecture, desert light, and archaeological sites just outside town.
The centre is small and easy to walk. Standin' on the Corner Park is the quick snapshot, Old Trails Museum gives the railroad and Route 66 story more substance, and La Posada shows how grand a railway hotel could be when Mary Colter and the Harvey House system were still shaping travel in the Southwest.
Winslow works best as a one-night Route 66 stop or a short detour from Flagstaff, Petrified Forest, or the Hopi mesas. Give it a few hours if you only want the downtown sights; add Homolovi State Park if you want the place to feel less like nostalgia and more like northern Arizona.
