Sun Valley to Oakhurst Road Trip Guide: Epic Scenic Drive

This route from Sun Valley, Idaho to Oakhurst, California traverses nearly 800 miles of stark contrast: from the volcanic moonscapes of central Idaho to the granite giants of Yosemite's doorstep. The drive follows U.S. 20/26 west to I-84, then picks up US 93 south through Nevada's Basin and Range, before crossing the Sierra Nevada via Tioga Pass (CA 120) — when open. Tioga Pass, at 9,943 feet, is the highest highway pass in California and typically closes from November to late May due to snow. Without the pass, the alternate is US 50 over Echo Summit, adding about an hour.

Historical trivia: The town of Oakhurst was originally named Fresno Flats in 1852 during the Gold Rush, but renamed in 1913 after the majestic oak trees that fill the Sierra foothills. Meanwhile, Sun Valley was America's first purpose-built ski resort, opening in 1936 after the Union Pacific Railroad sought a winter playground for its passengers. The road between them was never a single wagon trail; it's a patchwork of 20th-century highways.
