You can see Death Valley, the Grand Canyon, the Overland Trail, Yosemite Falls, and Route 66 from the state of California. Death Valley is located in Eastern California, while Yosemite Falls is in Yosemite National Park. The Grand Canyon is primarily in Arizona, but it's accessible from California. Route 66 runs through California, linking many iconic locations across the state.
