Fodor's Expert Review Exposition Park
Originally developed in 1872 as an agricultural park, this 160-acre park has a lovely sunken rose garden and three museums—the California African American Museum, the California Science Center, and the Natural History Museum of Los Angeles County—as well as an IMAX theater. There's also Los Angeles Memorial Coliseum where Olympic festivities were held in 1932 and 1984 and where USC games are now played. The newest addition to the park is the Banc of California Stadium, a 22,000-seat arena that's home to the LAFC soccer club. Good news for commuters: the Metro Expo Line, which connects the Westside to Downtown Los Angeles, has a stop at Exposition Park.
Note that the park and neighborhood are sketchy at night.
