South Lake Tahoe to Paso Robles: California's Ultimate Road Trip Guide

The first documented crossing of the Sierra Nevada by emigrant wagons in 1844 used what is now Highway 50, the same road you'll follow leaving South Lake Tahoe.

This route descends from the alpine crest at 6,225 feet to the Pacific's coastal range, passing through California's Central Valley—a landscape transformed by mega-droughts and dams.
