Ketchum to Redding: A Scenic Idaho-to-California Road Trip

This 700-mile route from Ketchum, ID (elevation 5,900 ft) to Redding, CA (elevation 560 ft) drops nearly a vertical mile in elevation. The drive follows US-20, US-93, I-84, US-95, and I-5, carving through the Snake River Plain, Oregon's high desert, and the Cascade Range.

Redding anchors the northern Sacramento Valley, gateway to Shasta Lake and Lassen Volcanic National Park. The contrast in landscapes is dramatic—snow-capped peaks in Idaho give way to sagebrush and volcanic terrain before plunging into oak-studded canyons.
