You've seen it. Honestly, if you’ve spent more than ten minutes in San Francisco, there’s no way you haven't. That massive, red-and-white steel tripod looming over the city like a prop from a 1950s sci-fi flick. It’s Sutro Tower. People often lump it in with Twin Peaks, but here is the first thing most folks get wrong: it isn't actually on Twin Peaks.
It sits on a slightly lower rise right next door, nestled between Twin Peaks and Mount Sutro. But because of how it dominates the skyline, everyone just points toward those famous peaks and assumes the tower is part of the package. It sort of is, but also totally isn't.

The Giant Crate and the "Praying Mantis"
Back in the 70s, San Franciscans absolutely hated this thing. I mean, they really loathed it. Legend has it that the legendary columnist Herb Caen once joked that Sutro Tower was just the shipping crate the Transamerica Pyramid came in. Others called it a "giant pitchfork" or a "menacing praying mantis."
It’s easy to see why. San Francisco is a city of Victorian charm and rolling green hills. Then, in 1973, this 977-foot-tall industrial skeleton just... appeared. It was loud. It was jarring. And for a while, it even had these glowing white lights on the legs that made people so crazy the city had to make the owners take them down.
Why does it even exist?
Basically, because San Francisco’s geography is a nightmare for TV signals. Before the tower, if you lived in a valley like Noe or the Castro, your reception was garbage. The hills blocked everything. The "Big Four" broadcasters—KGO, KPIX, KRON, and KTVU—realized they needed one massive, central point high enough to clear the peaks.
So, they built this. It weighs about 3.7 million pounds. To keep it from toppling over during the inevitable "Big One" earthquake, the foundation is incredibly over-engineered. We’re talking 15 million pounds of concrete. Two-thirds of the tower's total weight is actually buried underground, giving it a center of gravity that's basically 16 feet below the soil. It’s not going anywhere.
Exploring the Twin Peaks Connection
If you’re heading up there to take photos—which you should, because the views are unbeatable—you’re likely going to Christmas Tree Point on Twin Peaks. This is the classic tourist pull-off. From here, Sutro Tower looks like it’s right in your face.
- The Hike: You can't actually go inside the tower. Don't even try. It’s a high-security site owned by a private consortium. However, you can hike the trails around the base in the Mount Sutro Open Space Reserve. It feels like a cloud forest down there, all eucalyptus and fog, which makes the steel structure above look even more surreal.
- The View: If you want the "classic" shot of the tower, don't just stay in the parking lot. Walk up the wooden stairs to the top of the Noe Peak (the northern twin). You get a 360-degree view that includes the Golden Gate Bridge, downtown, and the tower itself.
- The Fog: Locals call the fog "Karl." Karl loves Sutro Tower. On some mornings, the entire city is buried in white, and only the very top prongs of the tower poke through. It looks like a ghost ship floating in the sky.
Honestly, the tower has transitioned from "neighborhood eyesore" to "indie icon." You’ll see it on t-shirts, tattoos, and brewery logos now. It’s become a shorthand for "the real San Francisco"—the part of the city where people actually live, away from the Pier 39 sourdough bread bowls.
Technical Weirdness and Public Access
Is it open to the public? Short answer: No. Long answer: Still no, but there's a workaround now.
In 2025, the tower owners launched a digital "immersive tour" on their official site. It’s kinda glitchy, but it’s the only way you’ll ever see the view from Level 6, which is 761 feet up. For the rest of us, we’re stuck on the ground.
If you're driving up Twin Peaks Boulevard to get a look, be careful. Car break-ins are a real thing at the summit parking lots. Do not leave a single thing in your car. Not a jacket, not a bag, nothing. Seriously.
Quick Stats for the Nerds
- Total Height: 977 feet (Salesforce Tower finally beat it for the "tallest" title in 2018).
- Elevation at Tip: 1,811 feet above sea level.
- Color: International Orange and White (required by the FAA so planes don't hit it).
- Broadcasts: It handles signals for 10 TV stations and several FM radio stations.
How to actually "do" Sutro and Twin Peaks
Don't just drive up, take a selfie, and leave. That’s boring. Instead, try this:
Start at the Haight-Ashbury intersection. Walk south up Ashbury Street. It’s a climb, but you get to see some of the best architecture in the city. Follow it until it hits Twin Peaks Boulevard. This route takes you past Tank Hill, which is a "local secret" spot with a killer view of the tower without the tour bus crowds.
From Tank Hill, it's a short but steep trek up to the main peaks. By the time you get to the top, you’ve earned that view. You’ll see the tower's three legs—the "waist" of the tower is actually narrower than the top, which gives it that weird, top-heavy look.
Check the weather before you go. If you can’t see the tower from downtown, you definitely won't see anything from the top of the peaks. You'll just be standing in a cold, damp cloud. But on a clear day? There’s nothing else like it in the world.
Actionable Tips for Your Visit
- Layer up: It is always 10 degrees colder and twice as windy at the base of Sutro Tower than it is in the Mission District.
- Timing: Go about 45 minutes before sunset. You get the "Golden Hour" light hitting the red steel, and then you can watch the city lights flicker on.
- Parking: If the main lot at Christmas Tree Point is full, try the smaller pull-outs along Twin Peaks Blvd further south.
- Photography: Use a wide-angle lens if you're at the base of the tower, but a telephoto lens from across the city (like from Alamo Square) makes the tower look absolutely massive behind the Painted Ladies.
Forget the haters from 1973. Sutro Tower is the weird, clunky heart of San Francisco's skyline. It’s functional, it’s ugly-beautiful, and it’s the best way to find your bearings when you’re lost in the Richmond.
Next Steps for Your SF Adventure
Check the official Sutro Tower website for their new virtual "Level 6" tour to see the 360-degree views you can't get in person. If you're planning a hike, download the Mount Sutro Open Space Reserve map to navigate the trails that lead directly under the tower's massive legs.
