Natural History Museum of Los Angeles County
900 Exposition Blvd., South Central
Since the early 1900s, L.A.'s Natural History Museum has been playing host to millions of artefacts from the past five or so billion years—and the collection keeps growing. (In 2011, they opened Dinosaur Hall.)

700 Exposition Park Dr., South LA
The Space Shuttle Endeavor is parked on-site, there’s an IMAX theater, and you can ride a high-wire bicycle perched 43-feet above the ground. Those are just some of the flashiest thrills: Little ones can experience the ice walls of the arctic, the aridity of the desert, and a view of the ocean floor. Plan to spend multiple hours.
