You’re standing on a jetty made of old gravestones. Seriously. If you walk out to the very tip of the Marina District, past the joggers in $200 leggings and the yachts bobbing in the harbor, you’ll find a strange, stony outcrop. This is the Wave Organ SF CA. It doesn't look like much from a distance—just a cluster of pipes sticking out of some recycled marble. But if you time it right, the Pacific Ocean starts singing to you. It’s not a choir. It’s more of a series of rhythmic gurgles, thumps, and liquid sighs. Most people show up at noon on a sunny Saturday, hear nothing but the wind, and leave disappointed. Honestly? That’s because they don’t understand how the tide works.
The Wave Organ isn’t a performance. It’s a collaboration.
Built in 1986 by Peter Richards and George Gonzales, this "acoustic-pipelined" sculpture is part of the Exploratorium’s permanent collection. It sits on a narrow spit of land called a jetty. The location itself is a bit of a local secret, even though it’s technically public. You have to want to find it. You have to walk past the Golden Gate Yacht Club, keep going when the pavement turns to dirt, and ignore the urge to turn back when you realize how isolated it feels.
The Macabre History Hidden in the Masonry
Take a close look at the benches. Notice anything? Some of the stone looks suspiciously like Victorian architectural salvage. That’s because it is. When the Wave Organ SF CA was being constructed, the builders used material from the demolished Laurel Hill Cemetery. San Francisco has a long, weird history of moving its dead to Colma, and the leftover granite and marble from those old vaults ended up here. You are literally sitting on pieces of 19th-century history while listening to the tides. It’s beautiful and creepy all at once.
Richards was inspired by a recording of a similar installation in Australia. He wanted to see if the Bay’s unique tidal swells could create a "natural" pipe organ. He teamed up with Gonzales, a master stonemason, to build it. They installed 25 organ pipes made of PVC and concrete at various elevations.

The pipes extend down into the water. As waves hit the pipes and air is pushed through them, you get sound.
Why the Tide is Your Only Friend Here
Here is the thing. If you go at low tide, the Wave Organ is silent. Dead silent. You’ll just see some dirty pipes and wonder why you walked all that way. To actually hear the music, you need to check a tide table. High tide is the sweet spot. Specifically, you want to be there about an hour or two before or after the peak high tide.
When the water level rises, it traps air in the pipes.
The "music" is low-frequency. Don't expect Mozart. It sounds more like a giant gargling or a distant percussion section. It’s subtle. You have to lean your ear against the openings of the pipes. Sometimes it’s a "bloop." Sometimes it’s a deep "thrum." It depends on how aggressive the Bay is feeling that day. On a stormy afternoon with heavy swells? It’s loud. On a glassy, calm morning? You might only hear the occasional splash.

Logistics for the Modern Explorer
Getting there is a bit of a trek. You can’t drive directly to the pipes.
- Parking: Park near the Crissy Field East Beach lot or the Marina Green.
- The Walk: It’s about a 10-15 minute walk from the parking areas. Follow the path toward the lighthouse/jetty.
- The Vibe: It’s usually windy. Even if it’s 70 degrees in the Mission, it’s 55 degrees out on that jetty. Bring a jacket.
There are no bathrooms out there. No snack bars. Just you, the recycled gravestones, and the rhythmic thumping of the Pacific. It’s one of the few places in San Francisco where you can actually hear the city breathing.
The acoustics are wild. Because of the way the pipes are angled, you can sometimes hear the sound of a boat engine from a mile away amplified through the stone. It’s an accidental surveillance device for the harbor.
The Science of the "Bloop"
Scientifically, it’s all about fluid dynamics and air displacement. As a wave enters the bottom of a pipe, it compresses the air inside. That air has to go somewhere, so it’s forced out the top. The varying lengths and diameters of the 25 pipes create different "notes." Richards and Gonzales didn't just throw these together; they tuned them to work with the specific wave patterns of the San Francisco Bay.

Is it art? Is it science? Is it just a very expensive plumbing project?
Honestly, it’s all three. In a city that is constantly being bulldozed and rebuilt, the Wave Organ SF CA feels like a permanent anchor. It’s built out of the literal bones of the city’s past and powered by the one thing that will never change: the ocean.
Most tourists flock to Pier 39 to see the sea lions. Sure, the sea lions are loud and smell like old fish. But if you want a more "San Francisco" experience—one that involves history, science, and a slightly haunting soundtrack—you walk to the end of the jetty.
Actionable Tips for Your Visit
- Check the Tide App: Download "Tides Near Me" or a similar app. Look for the "Golden Gate" station. If high tide is at 3:00 PM, aim to arrive by 2:00 PM.
- Bring Headphones? No. Put your phone away. The sound is delicate. If there are a lot of people talking, you won't hear a thing. This is a "quiet zone" by unspoken social contract.
- Look for the Plaques: There are small markers that explain the dedication of the site to Frank Oppenheimer, the founder of the Exploratorium, who was a huge supporter of the project.
- Photography: The light at sunset is incredible here. You get the Golden Gate Bridge in the background and the city skyline to your left. The textures of the old carved marble against the rusted pipes make for some great shots.
Go when the sky is a bit moody. The gray fog rolling in over the bridge matches the low-frequency groans of the organ perfectly. It’s a meditative spot. You sit on a piece of an old tombstone, watch the container ships crawl toward the Port of Oakland, and listen to the water play a song it’s been practicing since 1986.
It’s weird. It’s beautiful. It’s exactly what San Francisco used to be about before the tech buses took over. If you're looking for a place to think, or just a place to realize how small we are compared to the tide, this is it. Don't forget your windbreaker. Seriously.
To make the most of your trip, verify the high tide schedule at the NOAA website for the San Francisco station before you leave the house. Pair your visit with a stop at the Palace of Fine Arts nearby to see two very different styles of San Francisco architecture within a single afternoon. If the organ is quiet, don't worry—the view of the bridge alone is worth the walk.
