One of Oakland's top attractions, the Oakland Museum of California encompasses an inviting series of landscaped buildings displaying the state's art, history, and natural wonders. The museum is an excellent introduction to a tour of California, and its detailed exhibits can help fill the gaps on a brief visit. Step into the Natural Sciences Gallery to the sound of screeching gulls and travel through the state's myriad ecosystems, from the sand dunes of the Pacific to the coyotes and brush of the Nevada border.
