California is the third biggest state in terms of land size, and is larger than many countries. Nevertheless, getting around California can be very simple. In addition to interstates and US highways, California has one of the most expansive state highway systems in the United States. As with all travels in the United States, a rental car or RV is the best way to get around, although flying is also a feasible option as many major and low cost airlines also link cities within the state.
Another relaxing, convenient and inexpensive way to get around especially for holidaymaker is by rail. Amtrak’s Pacific Surfliner, Capitol Corridor and Coast Starlight routes are all particularly scenic ways to travel between some of the different regions of the state.
Los Angeles and San Francisco both have subway networks, in addition to light rail. Metrolink commuter rail serves much of Southern California, while BART and Caltrain commuter rail connect Bay Area suburbs to San Francisco. San Jose and Sacramento have light rail, and San Diego has a Trolley light rail and Coaster commuter rail services. Almost all counties run bus lines, and many cities run their own bus lines too. Intercity bus travel is supplied by Greyhound 
and Amtrak bus services.
