One of the most beautiful train trips in the country, Amtrak's Coast Starlight begins in Los Angeles and hugs the Pacific Coast to San Luis Obispo before it turns inland for the rest of its journey to Portland and Seattle. The Pacific Surfliner connects San Diego and San Luis Obispo via Los Angeles and Santa Barbara with multiple departures daily; the Sunset Limited runs from Los Angeles to New Orleans via Arizona, New Mexico, and Texas.
In the northern part of the state, the California Zephyr travels from Chicago to Emeryville (San Francisco) via Denver.
