By train
BART is the regional heavy rail service which will connect you to San Francisco, Oakland, and other cities in the Bay Area. Sadly, there is no BART station in Emeryville, but simply get off BART at the MacArthur station in Oakland and take the free Emery-Go-Round (http://www.emerygoround.com/) shuttle. Warning: MacArthur is not recommended at night due to high danger of violent crime.
Emeryville is home to the Bay Area's major Amtrak (http://www.amtrak.com) station, which is located just east of the Public Market. Amtrak buses run from the Emeryville station across the Bay Bridge to San Francisco. Two long distance Amtrak routes run daily to and from Emeryville: The California Zephyr (http://www.amtrak.com/tra...) route connects Emeryville to Chicago via Denver, Salt Lake City, and Reno. The Coast Starlight (http://www.amtrak.com/tra...) route runs from Los Angeles to Portland Oregon and Seattle via Emeryville.
Amtrak also operates two short distance trains through Emeryville: The Capitol Corridor (http://www.capitolcorrido...) runs 16 times daily 11 on weekends and holidays between Sacramento and Oakland, with some trains running south to San Jose. The San Joaquins (http://www.amtrak.com/ser...) runs 4 times daily between Bakersfield, Stockton and Oakland, with a stop in Emeryville.
By car
From San Francisco, take I-80 East and exit on Powell St.From points East, take I-80 West and exit on Powell St.
The complex freeway intersections just to the south of Emeryville are referred to as the Maze for good reason. Here are some tips to help your confusion:
Be aware that when traveling through Berkeley and Emeryville, I-80 west travels on the same road as I-580 east and vice versa.
When traveling from I-880 north onto I-80 east, you cannot exit at Powell. Instead merge right furiously and exit at Ashby/Shellmound. Take the Shellmound fork and right at Shellmound. Go straight and you'll see the Public Market and the rest of Emeryville shortly.
By plane
Oakland International Airport OAK is the obvious choice, but SFO will also do. From the airports, see rail section on BART.
