If you or your kids are a fan of the Old West and Native American history, you can while away a whole lot of time at the Autry National Center, a history-focused museum in Griffith Park that features more than 500,000 works of art and artifacts. For the kids, there are a number of hands-on exhibits, and kids can pan for gold in the Gold Rush attraction, open most weekends.
