State Route 78
State Route 78 is Scarlett Johansson before Lost in Translation. Or, if you prefer, Ryan Gosling before The Notebook. That tortured metaphor is a roundabout way of saying that SR 78, in Arizona’s far eastern reaches, is the most beautiful road you’ve probably never heard of. This 34.2-mile drive, which extends into New Mexico, features everything from vibrant grasslands to mountain vistas, with a little roadside history along the way.
