Rail

BART is a rapid transit system serving Berkeley and the entire Bay Area. BART operates as a subway through Berkeley and has 3 underground stations--Ashby (at Ashby Avenue and Adeline Street in South Berkeley), downtown Berkeley (at Shattuck Avenue and Center Street), and North Berkeley (at Sacramento and Delaware Streets, which is not actually in North Berkeley). BART offers convenient train service to many regional destinations, such as Union Square in San Francisco, as well as service to both local airports (Oakland and San Francisco).

Daily service to Berkeley is provided by the orange line, which operates between Richmond and Fremont. On weekdays, the red line operates between Richmond and Millbrae via San Francisco. On Saturdays, the red line does not operate as far south as Millbrae and instead ends at Daly City. On Sundays and during the evening, passengers bound for San Francisco must ride the orange (Fremont) line to the MacArthur station and make a timed transfer across the platform to the yellow line.The yellow line serves San Francisco and SFO.

BART fares vary by distance traveled, and unlike any other public transit service within California, there are no easily obtainable discounts available to seniors, the disabled, or children. BART does offer transfer discounts for passengers wishing to connect with various bus routes throughout the Bay Area, but the discount often is a mere 25¢.

Bus

AC Transit is the primary bus operator within Berkeley and the East Bay area. Most routes converge in downtown, with daily bus connections here to: Amtrak's Berkeley station (Route 51B trips terminating at the station), Berkeley Marina (Route 51B trips terminating at the marina), the Gourmet Ghetto restaurant district (Routes 7 and 18), Greyhound bus depot in Oakland (Route 18), Lawrence Hall of Science (Route 65), downtown Oakland (Route 18), Oakland's Rockridge business district (Routes 49 and 51B), downtown San Francisco (Route F), and the Telegraph Avenue business district (Routes 1 and 1R). Tilden Regional Park is accessible via Route 67 on weekends.

AC Transit provides extensive peak period bus service to/from San Francisco on weekdays in addition to Route F.  Routes E, FS, G, H, and J pick up at various points throughout the city and take passengers to San Francisco in the morning, returning in the afternoon and early evening hours. Route Z operates in the reverse direction, taking passengers to Berkeley in the morning, returning to San Francisco in the afternoon.

Bus fares are $2.00 for adults, plus 25¢ additional for a transfer good on one connecting bus. Transbay buses to/from San Francisco cost $4.00 and include one free transfer. Seniors, the disabled, and older children receive discounted fares, and young children are free. Day passes are not available, and no transfers to BART are available. Transfers from BART provide a 25¢ discount.

University Shuttles

UC Berkeley ("Cal") provides shuttle bus service known as Bear Transit in and around the campus, which is situated on the east side of downtown Berkeley. Most shuttles provide connections to the downtown Berkeley BART station, as well as numerous AC Transit bus routes.

Bear Transit is free to Cal students and employees with proper ID. All other passengers pay a nominal fare for daytime bus service. Evening shuttles are free for all passengers regardless of school affiliation.

Owl Services

Late night and early morning bus service is available via Routes 800, 802, and 851. Route 800 operates between San Francisco, Oakland, and points north, while Routes 802 and 851 stay within the East Bay. There is no late-night and early morning BART service, so the "All Nighter" routes fill the gap in service. This owl service arrangement is in effect beginning around midnight daily and lasts until approximately 5 AM on weekdays, 6 AM on Saturdays, and 8 AM on Sundays and holidays.
