Lawrence Berkeley National Laboratory is a multidisciplinary national laboratory located in Berkeley, California on a hillside directly above the campus of the University of California at Berkeley. The site consists of 76 buildings located on 183 acres, which overlook both the campus and the San Francisco Bay. [More Visitor Information.]

Site Access

Beginning Monday, Sep. 28, call 510-387-0524 with urgent questions about site access and other logistics. 

All non-LBNL employees attending must obtain a visitor bus pass or a visitor parking pass in advance.  This applies whether you are taking the shuttle or driving.  Check-in with Security and picture ID is required.  LBNL Security requires the names, citizenship and country of birth of all visitors.  

Please fill out this form to request site access to Berkeley Lab.

The Blackberry Canyon entrance is closest to the CRT Building. The shuttle buses stop at the 65 building or main shuttle bus stop (across the street from CRT).

Parking

Parking at LBNL is limited due to a number of construction projects. We recommend car pooling, LBNL shuttle, or taxi. If you drive, a parking space may be reserved.  For those visitors who plan to drive to LBNL, we will reserve general parking near the CRT Building.

Shuttle Information

There is a Lab shuttle bus from various locations around the City of Berkeley, including near the Downtown Berkeley BART station.  If you plan to take the LBNL shuttle, you are required to have an LBNL Visitor Bus Pass  (requires advance notice) and picture ID to show the bus driver. 

Bay Area Rapid Transit Train (BART)

The Downtown Berkeley BART station is two short blocks from the LBNL shuttle line on the corner of Addison and Shuttuck.  The LBNL Blue Shuttle Bus will take you to the Blackberry Canyon entrance and the CRT Building.  The CRT building is across the street from LBNL's main bus stop. [BART Web site]

Lodging

It is recommended lodging reservations be booked as early as possible. You can book a hotel anywhere in the Bay Area that has convenient access to BART and get to the meeting.
