Nearly 1.6 million people climb the hill to Griffith Observatory every year, making it the single most-visited public observatory on the planet.
Most of them show up, snap a photo of the Hollywood Sign, and leave without digging into the building’s deeper history.
This summer, a new guided experience from a third party company is finally letting locals see what’s actually inside the building everyone photographs but almost nobody explores properly.
12 August 2026 17:30 + more dates
The Griffith Observatory Guided Tour + Planetarium Show is a small-group experience operated independently of the Observatory itself, led by guides who previously worked at the facility, running daily through the rest of summer 2026.
It’s a separate, independently operated tour, not something run or endorsed by the Observatory itself, and it won’t get you past any velvet rope the Observatory doesn’t already leave open to the public.
Griffith Observatory is free to enter, its own museum guides staff every gallery at no charge, and the Observatory has no involvement in how this particular tour is booked, scheduled, or run. What you’re really paying for here is a narrated, structured version of a visit you could otherwise piece together yourself for free.
Here’s what you’ll learn from the guide along the way and why it’s worth a visit.
A building with more square footage than you’d guess
When Griffith Observatory opened in 1935, it was a comparatively modest 27,000 square feet.
A major renovation nearly tripled that footprint, and today the building holds roughly 67,000 square feet of exhibit galleries, most of it built discreetly below grade so the original 1930s exterior looks untouched from the lawn.
That’s the detail insider tours are built around, since the guides know exactly which hallways lead to expanded wings most guests never realize exist.
The independently run tour covers this expanded space over 60 to 90 minutes, walking through the building’s science exhibits, architecture, and Hollywood history, led by guides with prior experience at the facility.
Since general admission is free and the Observatory’s own museum guides are stationed throughout the galleries at no cost, this tour’s real value is a structured, narrated walkthrough with a dedicated tour guide rather than access you couldn’t otherwise get on your own.

The Tesla coil everyone photographs but nobody understands
Ask most visitors what the giant crackling machine in Wilder Hall does, and you’ll get a shrug.
The observatory’s Tesla coil has been zapping lightning-like arcs across its alcove since 1937, and it didn’t even start there.
It originally belonged to a Massachusetts physician who used high-voltage currents in his medical practice before donating the components to the city. Staff demonstrate it live several times a day, and it remains one of the most photographed exhibits in the building.
The insider tour context turns it from a cool photo op into an actual story, which is the whole appeal here.
Yes, this is the La La Land observatory
If the building looks familiar even if you’ve never visited, that’s because Hollywood has used it as a backdrop for decades.
Rebel Without a Cause was the first film to shoot here and the first to show a planetarium on screen for its real purpose, and Damien Chazelle built La La Land‘s entire planetarium dance sequence as a direct homage to that legacy.
The observatory leans into it too, screening Rebel Without a Cause on-site during anniversary events, most recently for its 70th anniversary in 2025.

What else is happening this summer
August is stacked with additional programming beyond the tour itself, making it the perfect time to visit:
- La La Land at Griffith Observatory, August 17: Experience the Academy Award®-winning film on the big screen at Griffith Observatory, where Sebastian (Ryan Gosling) and Mia (Emma Stone) dance, dream, and fall in love.
- Public Star Party, August 22: Free stargazing through dozens of telescopes set up on the lawn, weather permitting
- Night Gallery: The Stars of Summer, August 31: An evening program inside the Samuel Oschin Planetarium blending science talks with cosmic visuals, tickets running $45 to $50
- Daily Tesla coil demonstrations and planetarium shows: Running on a rotating schedule throughout the day, included with general admission
Making the most of a day on the hill
Griffith Observatory sits inside Griffith Park, just far enough from the Hollywood grid to feel like an actual escape without leaving city limits.
Pair the tour with a short hike up to the Hollywood Sign viewpoint beforehand, then time your visit so the guided tour wraps right around golden hour, when the whole city starts lighting up below the terrace.
A few tips that make the day actually work:
- Parking fills up fast, especially on weekends, so arrive at least 30 minutes before your tour time or use the free DASH Observatory shuttle from the Vermont/Sunset Metro station instead
- The lawn views are free and unticketed, so even if you’re only booked for the guided tour, budget extra time to wander the grounds before or after
- Bring a layer, since the hill catches wind even in August, and the terrace gets noticeably cooler once the sun drops
- Stick around after sunset if your schedule allows it, since the building and skyline views hit differently once the city lights come on
