With a history dating to the early 1920s, this studio lot was home to some of Hollywood's most luminous stars, including Rudolph Valentino, Mae West, Mary Pickford, and Lucille Ball, who filmed episodes of I Love Lucy here. Paramount is probably the most authentic studio tour you can take, giving you a real sense of the film industry's history. It's also the only studio left in Hollywood—all the others are in Burbank, Universal City, or Culver City. The lot still
churns out memorable movies and TV shows, such as Forrest Gump, Titanic, and Star Trek. You can take a two-hour studio tour or a 4½-hour VIP tour, led by guides who walk and trolley you around the back lots. As well as gleaning some gossipy history (see the lawn where Lucy and Desi broke up), you'll spot the sets of TV and film shoots in progress. Reserve ahead for tours, which are for those ages 10 and up. You can also be part of the audience for live TV tapings. Show tickets are free; you must reserve ahead of time.
