Trip length and key highways: Depart Eureka on US-101 south, then CA-299 east to Redding. Pick up I-5 north to Weed, then US-97 north to Klamath Falls. Continue on US-20/US-395 to Burns, then US-20 east to I-84 in Idaho. From I-84, exit at Twin Falls.

From redwood forests to sagebrush steppe, this route showcases dramatic shifts. In California, you'll see towering redwoods (Avenue of the Giants) and volcanic peaks (Mount Shasta). Oregon offers Crater Lake (a deep caldera lake) and the high desert of the Great Basin. Idaho's Snake River Canyon is a surprising green ribbon.

• Hidden gem: Lava Beds National Monument (California) has volcanic tubes and petroglyphs, easily missed but worth a detour.
