The Expo Line is the newest addition to rail travel in greater Los Angeles. In 30 minutes' time, one can go is from downtown L.A to Culver City, at the CC stop*. The same trip by car in some freeway traffic is not much shorter or longer given the typical freeway L.A. traffic.
Expo Line ridership is steadily building, not generally very crowded like its sister Blue Line. After departing the rail line, one can discover major CC points of interest by foot. In 5 minutes, arrive at the Helms District for a nice stroll, historic sight seeing, and limited eaterie options. In 10 min of a walk from the rail station, one can get to downtown Culver City for the movies, shopping, art galleries and much more dining options. All the while in discovering the immediate area, visitors can feast their eyes on a good number of artistic murals and stunning architectural. See pics!
*As of now, the Expo Line ends right in CC, but by 2020 or so, another phase of the line will be completed to go all the way to CC's neighbor, Santa Monica.
Pay $2.00 one way on Expo. Buy a tap card and load money on it at the station for multiple trips.
Bussing it from LAX to Culver City is convenient. From the lower level arrivals at the airport:
-Catch a free LAX "G" shuttle bus (stand under the clearly marked shuttle area) and head to the LAX City Bus Center or to the Green Line Aviation Station, both about a mile or less away.
Exit whichever destination option and wait for the Culver City 6 bus. CC bus costs $1 one-way. Route 6 travels to much of Culver City as well as parts of Los Angeles, esp major point of interest, Westwood Village/UCLA area. There is "Rapid" service for route 6 Mon-Fri, which helps to cut down on ride time.
