Natural Landscapes and Attractions

The route passes through several distinct ecosystems. From Mendocino's coastal bluffs and redwood groves (like Montgomery Woods State Natural Reserve) to the oak woodlands of the Coast Range, then the agricultural plains of the Sacramento Valley, and finally the sagebrush steppe of the Great Basin. In Nevada, the Humboldt River valley offers a green ribbon through the desert.
