1. The key facts before you go
Griffith Observatory is at 2800 E Observatory Road, Los Angeles, CA 90027, on the south slope of Mount Hollywood inside Griffith Park. It is owned by the City of Los Angeles and has been free to enter since it opened on June 29, 1935.
Hours: Tuesday through Friday, noon to 10pm. Saturday and Sunday, 10am to 10pm. Closed Monday every week of the year.
Admission: Free. The only paid experience is the Samuel Oschin Planetarium, where shows cost $3 to $7 per person depending on age.
Parking: Limited paid parking lines the road to the Observatory and fills by midmorning on weekends. The smarter move is transit or the hike — both are detailed below.
The Observatory sits about 1,134 feet above sea level. October is consistently one of the clearest months in Los Angeles, which makes fall the optimal season for views, telescope evenings, and avoiding the summer crowds. Details verified October 2026; confirm hours before visiting as holiday schedules can vary.
2. Three exhibits inside worth slowing down for
Give yourself at least 90 minutes to see the building properly. Three exhibits are worth pausing at rather than passing by.
The Foucault Pendulum hangs in the W.M. Keck Foundation Central Rotunda — a 240-pound bronze ball swinging from a 40-foot cable. The pendulum appears to slowly rotate over the course of the day, but it is not rotating: the Earth is rotating beneath it. Every 15 minutes or so, it knocks over one of the metal pins arranged in a circle on the floor. The same demonstration has run here since 1935. Watch it for five minutes and you'll understand why Leon Foucault's 1851 experiment in Paris was considered one of the most elegant proofs in science.
The Tesla Coil is in the Wilder Hall of the Eye on the lower level. The demonstration sends 50,000 volts of electricity arcing through the air — the largest such display on public view in California. Staff run it several times daily and it is genuinely startling even when you know it's coming.
The Zeiss Refractor Telescope sits in the east dome and has been in use since the Observatory opened in 1935. More than 8 million people have looked through it, making it the most-used public viewing telescope on Earth. It's free to use and opens from sunset to 9:45pm on clear evenings. The moon is the most dramatic target; Jupiter and Saturn are excellent on a clear fall night.
3. The Samuel Oschin Planetarium
The domed auditorium in the main hall runs three shows per day — typically in the late afternoon and evening on weekdays, starting at noon on weekends. Shows run about 45 minutes with a live narrator and full digital projection. Current programs (confirmed October 2026) include presentations on the life cycle of stars and the night sky above Los Angeles.
Tickets cost $7 for adults, $5 for seniors (60+), and $3 for children ages 5 through 12. Children under 5 are not admitted. Tickets are available at the box office inside the Observatory or in advance at griffithobservatory.lacity.gov. On Saturday afternoons, the first two shows regularly sell out by midmorning, so buying online the day before is the safer approach.
The planetarium was last renovated in 2006 and is considered one of the best in the Western United States. The seats fully recline under the dome. Even if you've been before, the show lineup rotates — a new program may have been added since your last visit.
4. The history: a criminal's gift that became an LA icon
Griffith J. Griffith made a fortune in 1880s Los Angeles real estate and in 1896 donated 3,015 acres of land to the city — the land that became Griffith Park, the largest urban park in the United States with a natural landscape. In 1903, Griffith shot his wife in a hotel room in Santa Monica. She survived but lost an eye. He served two years in prison for attempted murder.
After his release, Griffith donated money for the construction of an observatory and an outdoor amphitheater. The city government, embarrassed by the donor's record, refused the bequest for years. It was not until after Griffith's death in 1919 that the city accepted the funds. Construction began in 1933. The Observatory opened June 29, 1935 in Art Deco style, designed by John C. Austin and Frederick M. Ashley. The copper domes have turned the signature pale green that is visible from much of the LA basin.
In 1955, director Nicholas Ray chose the Observatory for the central scenes in *Rebel Without a Cause*. James Dean, Natalie Wood, and Sal Mineo filmed the knife fight, the footrace, and the film's final sequence here. The Observatory has maintained a dedicated exhibit on the film ever since. In October 2026, a special anniversary screening takes place at Griffith Park on October 27.
5. Getting there: four options, ranked by ease
DASH Observatory Bus (recommended): The LA Department of Transportation runs the DASH Observatory/Los Feliz route daily, 10am to 10pm, with buses every 15 to 20 minutes. The route starts at the Vermont/Sunset station on the Metro Red and Purple lines, runs through Los Feliz past the Greek Theatre, and ends at the Observatory front lawn. Cost is $0.50, or $0.35 with a Metro TAP card. Take the Red or Purple line subway to Vermont/Sunset, then board the DASH — it is the easiest option from most of central Los Angeles.
Hike from Fern Dell: The Fern Dell trailhead is off Fern Dell Drive in Los Feliz, about 0.7 miles south of the Observatory. The hike is approximately 1.5 miles with 600 feet of elevation gain through a shaded ravine. Allow 40 to 50 minutes. It is one of the better urban hikes in LA and gets crowded after 9am on weekends.
Drive and park: Paid parking is available on the road to the Observatory. It fills by 11am on Saturdays. If you drive, arrive before 10am on weekends or plan to park in Los Feliz and take the DASH up.
Rideshare: Drop-off at the Observatory front entrance works well for an evening visit. Pick-up from the same point is straightforward, and the walk from the entrance to the main building is short and flat.
6. What you can actually see from the terrace
The outdoor terrace wraps around the Observatory on three sides and is free to access with no ticket required. On a clear October day, the view north puts the Hollywood Sign on the Santa Monica Mountains about 1.5 miles away — close enough to read the letters without binoculars. The view south and east covers the entire Los Angeles basin: Downtown LA, the San Gabriel Mountains behind it, and on the clearest days the Pacific Ocean about 18 miles to the southwest.
At sunset, the western terrace faces directly into the sky above Hollywood and the Sunset Strip. The combination of the orange sky and the Observatory's pale green copper domes is one of the most photographed views in the city.
The terrace is busiest at sunset on weekends. If you want it to yourself, come on a Tuesday or Wednesday around 1pm: the hilltop view is identical, the terrace is nearly empty, and you'll have the Foucault pendulum to yourself inside.
For a meal before or after the Observatory, the neighborhood at its base is one of LA's most walkable. The Los Feliz neighborhood guide covers the best options on Vermont Avenue and Hillhurst Avenue.
7. When to go, and answers to the most common questions
Best time to visit: October through December is the optimal window in Los Angeles. Air quality is better than summer, temperatures are in the mid-70s by day and drop to the 50s after dark, and fall skies are consistently clear enough for evening telescope viewing. Avoid Santa Ana wind events, which can spike temperatures and reduce visibility — check a local forecast before heading up.
Is it really free? Yes. The building, the exhibits, the terrace, the Foucault pendulum, and the Zeiss telescope (evenings) are all free. Only the Samuel Oschin Planetarium shows cost money ($3-$7 per person).
Can I see the Hollywood Sign? Yes, clearly. From the north terrace, the sign is about 1.5 miles away on the ridge above. It is one of the closer vantage points in the city without requiring a separate hike.
Is there food? The Cafe at the End of the Universe is inside the Observatory and serves sandwiches, salads, and coffee from noon to closing. It is convenient rather than a destination. For a proper meal, Los Feliz has several good restaurants within 20 minutes on the DASH bus.
How long should I plan? Budget 90 minutes minimum for the exhibits and one planetarium show. If you add sunset on the terrace and Zeiss telescope viewing at 9pm, two to three hours is a comfortable visit. An evening that starts at 6pm, catches the sunset, takes in one planetarium show, and ends with the telescope at 9:30pm is one of the best free evenings available in Los Angeles.
