Highway 12 Scenic Byway, Utah
This route winds between Capitol Reef and Bryce Canyon national parks. It features sandstone canyons, cute little towns and striking colors that can only be made by nature. Despite the fact that it's only 122 miles (180 km) there are still many things to see like Hell’s Backbone Grill, Kodachrome Basin State Park and the Anasazi State Park Museum.
US Highway 50
The BIG one… Highway 50 is a cross-country, border-to-border road, that goes from San Francisco to The Chesapeake Bay. It runs through a dozen states and four state capitals. It offers more sites and views than I could ever list, and it's gorgeous beyond imagination. You'll cover a distance of 3,200 miles (over 5,100 km) and experience an adventure like no other. Where to stop? It all depends on you, nothing but freedom on this road trip.
