Sacramento to Sun Valley Road Trip Guide: Epic Scenic Drive

The drive from Sacramento to Sun Valley follows the old Siskiyou Trail, used by Native Americans and fur trappers, now largely paralleled by Interstate 5 and US 97. The route climbs from California's Central Valley at 30 feet elevation to Sun Valley's 5,920 feet, crossing the Cascade Range and Modoc Plateau. Note that Oregon's OR-58 is prone to winter closures due to heavy snow, a key logistical factor.
