Carson City to Ketchum Road Trip Guide: Epic Scenic Drive

From Carson City, Nevada, at 4,679 feet elevation, to Ketchum, Idaho, at 5,840 feet, this road trip traverses the heart of the Great Basin Desert and the rugged Sawtooth Range. The route primarily follows US-50 East, known as the 'Loneliest Road in America,' and US-93 North through Nevada, then Idaho State Highway 75 into the Sawtooth Valley.

A fascinating historical detail: US-50 was once the primary transcontinental highway, and its desolate stretches still feature remnants of Pony Express stations and ghost towns. The journey spans approximately 580 miles, with a pure driving time of about nine hours, but most travelers spend at least two to three days to absorb the landscapes and hidden treasures.

Key highways include US-50 East out of Carson City, NV-360 north to US-6 east, US-93 north through Ely and Wells, NV, then I-84 East briefly in Idaho, and finally ID-75 North through Stanley to Ketchum. The drive passes by Great Basin National Park, the fictional setting for the town in 'The Simpsons,' and ends at the doorstep of Sun Valley Resort, America's first destination ski resort.
