Griffith Park Observatory

Though technically outside of the neighborhood, this LA landmark feels like an essential party of any Hollywood visit. The vista here is stunning, particularly at night when Los Angeles twinkles below. Inside you'll find a bevy of exhibits, including a Foucault pendulum, Tesla coil and planetarium show. Give yourself plenty of time before the 10pm closing to gaze through the 12-inch refracting telescope on the roof, otherwise you can look through the far less crowded modern, reflecting telescope on the front lawn.
