The Lawrence
Offers many hands-on science exhibits, especially good for children. Since 1968, the Lawrence has been dedicated to creating innovative science learning experiences. The outdoor plaza (free) is popular for its whale and DNA sculptures to climb on, and features a panoramic view of the Bay Area: San Francisco, the Golden Gate Bridge, Oakland and the Bay Bridge. The science center includes a planetarium, a 3D theater, an Animal Discovery Zone, Outdoor Nature Lab, and an area for young explorers.
A half-hour's walk north of the UC Berkeley campus. Especially nice for watching the sunset, with a view of the bay.
Part outdoor museum, park, and biological research facility for the University of California, the garden hosts over 12,000 different species of plant life.
Amphitheater that mostly hosts musical performances by well-known artists.
Above the Berkeley campus, Memorial Stadium plays host in the fall season to UC Berkeley football games. But if you want to watch a game for free, head above the canyon to Tightwad Hill, a hill where students and the public gather to watch games. It's also an ideal location for spectacular views of the Bay Area when there's not a game going on. Anyone is free to come as long as they pick up their own trash and don't wear the colors of Stanford University (red).
