The vista from the Griffith Observatory is stunning, particularly at night when the whole of Los Angeles twinkles below you. Inside this hilltop landmark, which is celebrating its 90th birthday this year, you’ll find a selection of free exhibits—including a Foucault pendulum and a Tesla coil—as well as ticketed planetarium shows. Give yourself plenty of time before the 10pm closing to line up and gaze through the 12-inch refracting telescope on the roof. Otherwise, don’t worry: You can look through the far less crowded modern, reflecting telescopes often set up on the front lawn.
Time Out tip: Parking in the congested lot and along the hill now costs about $10 per hour—though you can take a DASH bus up there for only 35 cents with a TAP card.
