MuseumsGriffith Observatory
A free, iconic Art Deco observatory perched on Mount Hollywood with planetarium shows, hands-on space and science exhibits, public telescopes on clear evenings, and some of the best panoramic views of LA and the Hollywood Sign. As much a destination for the setting as the science, it gets busy at sunset. Admission is free (planetarium shows ticketed), it is closed Mondays, and parking fills up fast, so arrive early or use the shuttle.
