Metro Rail covers only a small part of L.A.'s vast expanse, but it's convenient, frequent, and inexpensive. Most popular with visitors is the underground Red Line, which runs from Downtown's Union Station through Mid-Wilshire, Hollywood, and Universal City on its way to North Hollywood, stopping at the most popular tourist destinations along the way.
The light-rail Green Line stretches from Redondo Beach to Norwalk, while the partially underground Blue Line travels from Downtown to the South Bay. The monorail-like Gold Line extends from Union Station to Pasadena and out to the deep San Gabriel Valley and Azusa. The Orange Line, a 14-mile bus corridor, connects the North Hollywood subway station with the western San Fernando Valley.
Most recently extended was the Expo Line, which connects Downtown to the Westside, and terminates in Santa Monica, two blocks from the Pacific Ocean.
Daily service is offered from about 4:30 am to 12:30 am, with departures every 5 to 15 minutes. On weekends trains run until 2 am. Buy tickets from station vending machines; fares are $1.75, or $7 for an all-day pass. Bicycles are allowed on Metro Rail trains at all times.
