The best option for parking at the Berkeley campus is in the new public lot built on the eastern edge of the campus - next to the recently rebuilt football statium. This is known as the Maxwell Garage and is operated by a commercial firm.
If your approach is from I-80/I-580, then exit on University Avenue and travel to the end, at which point you should turn left and then turn at the second right on to Hearst. Your first right turn will be encountered at the top of the hill, on to Gayley - take this right turn and then look for the parking lot on your left. Google Maps outlines this route HERE
If your approach is from Emeryville (such as the Sheraton points Hotel) then there are a variety of local roads you can use to avoid the highway. google Maps outlines this route HERE
Once your Car is Parked
You can easily walk from the parking lot to Sibley Auditorium in less than 10 minutes. Sibley is located in the Bechtel Engineering Center.
