🖼️ Griffith Observatory

The Big Picture anchors the Gunther Depths of Space hall — measuring 152 feet wide and 20 feet tall, it is the largest astronomically accurate image ever assembled, a single deep-sky exposure holding roughly a million galaxies, stars, and asteroids that visitors examine up close through a mounted brass telescope. In the Wilder Hall of the Eye, a crackling Tesla coil demonstrates how humans learned to harness electricity, one of the museum's most theatrical draws. The central rotunda holds the Foucault pendulum, whose 240-pound brass ball swings in a slowly rotating plane that quietly proves the Earth turns beneath your feet, framed by Hugo Ballin's 1935 zodiac murals overhead.

Downstairs, the Leonard Nimoy Event Horizon theater screens the observatory's history, while the Cosmic Connection corridor lines a 150-foot wall with celestial-themed jewelry tracing the timeline of the universe. Don't miss the meteorite specimens, the walk-on scale model of the solar system in the Gottlieb Transit Corridor, and the camera obscura tucked off the main lobby — a 1935 original that projects a live, rotating image of the surrounding Los Angeles hills onto a viewing table.

Griffith Observatory offers free guided tours led by its team of Museum Guides, who circulate through the halls daily and can be flagged down for on-the-spot explanations or scheduled walk-throughs that unpack the building's Art Deco symbolism and the science behind each exhibit. The signature "Once a Day" talk gathers visitors in the central rotunda for a short, lively primer on what makes the observatory unique before pointing them toward the day's highlights.

Every clear evening the observatory is open, staff run free telescope demonstrations on the roof and front lawn, guiding the public through the Zeiss 12-inch refractor — the most-used telescope on Earth — and portable scopes trained on the Moon, planets, and bright stars. Monthly public star parties, hosted with the Los Angeles Astronomical Society, the Sidewalk Astronomers, and the Planetary Society, fill the lawn with dozens of amateur telescopes and expert volunteers.

Inside the Samuel Oschin Planetarium, live presenters — not recordings — narrate each show beneath the Zeiss star projector, answering questions in real time. Private and group astronomy tours can also be booked, and many pair a docent-led visit with a walk toward the nearby Hollywood Sign.

Tuesday through Friday: 12:00 PM - 10:00 PM. Saturday and Sunday: 10:00 AM - 10:00 PM. Closed Mondays: The observatory is always closed on Mondays.

Best for views: Arrive 60-90 minutes before sunset to watch the transition from daylight to city lights. Telescope viewing: Free public telescope access every clear evening the observatory is open. Least crowded: Tuesday and Wednesday evenings after 7 PM offer the most space.

Observatory admission: Completely free, including all exhibits and telescope viewing. Samuel Oschin Planetarium: $7 adults, $5 students/seniors, $3 children (5-12). Parking on-site: $10 per hour on weekends and evenings (cash and card accepted).

DASH shuttle from Vermont/Sunset Metro: $0.50 each way, runs every 20 minutes on weekends. Guided group tours: $45-70 per person (2-3 hours including transportation from Hollywood hotels). Private astronomy tours: $250-400 for up to 6 people, includes telescope time and expert narration.

Arrive before sunset: This is the single most popular time, and the experience of watching day turn to night from the terrace is worth planning around. Layer up for evenings: The hilltop temperature drops quickly after dark, even in summer — bring a jacket if you plan to stay for telescope viewing.

Planetarium tickets sell out: Buy them at the box office when you arrive since they cannot be purchased online, and popular shows fill within the first hour. Combine with Hollywood Sign hike: The sign is visible from the observatory grounds and several trails connect the two attractions. Accessible by public transit: Metro Red Line to Vermont/Sunset, then DASH observatory shuttle — no car needed. Photography gear: Bring a tripod for night shots of the city lights and a telephoto lens for close-ups of the Hollywood Sign.
