San Francisco Bay’s got a new star these days: a 2,000-pound Steller sea lion folks are calling “Chonkers.” He’s hanging out near Pier 39, basically turning a regular bay-side stroll into a bit of a spectacle. People from Sausalito’s shoreline to San Rafael’s tidal flats are snapping photos and swapping stories. Chonkers just towers over the other sea lions and sometimes stares right back at the crowd. He’s become a bit of a local legend almost overnight.
This Steller sea lion has been hanging around the Pier 39 docks for about a month now. Crowds keep spilling onto the waterfront, and you can feel the buzz all the way to Marin’s ferry landings in Tiburon and Sausalito. Marin locals from places like San Anselmo, Corte Madera, and Novato have been trading photos and shaky phone videos, hoping to catch Chonkers basking in the sun. It’s become a thing—everyone wants their own glimpse.
Steller sea lions are way bigger than the California sea lions we usually see around Marin. Male Steller sea lions can weigh up to 2,500 pounds and stretch out to about 11 feet long. They usually live up north in Alaska’s cold waters. But sometimes, especially when currents change or food gets scarce, they’ll wander down to San Francisco Bay. Researchers aren’t totally surprised when one shows up here, though it’s still a bit of a treat.
Harbormaster Sheila Chandor says these visits happen “every few years.” When Chonkers showed up, Pier 39’s viewing area turned into a Bay Area event. People from Fairfax, San Rafael, and Novato flocked to the docks, keeping a safe distance but hoping for a close look. The sight of Chonkers waddling around, dwarfing the other sea lions, has become a local conversation starter.
A Bay-Wide Wanderer: Why They End Up Here
NOAA scientists say Steller sea lions like colder, northern waters, but sometimes strong currents and the hunt for food bring them south. Around Pier 39, you might see up to two thousand sea lions at peak times. That’s a wild scene, honestly—not something Marin folks get to watch every day. For people from Sausalito to Larkspur, it’s a rare chance to see the Bay’s wildlife up close. You might even catch yourself thinking, “Is this really my daily commute?” Sometimes, the Bay just surprises you.

Chonkers has parked his mass near Pier 39, but locals from San Rafael and Corte Madera usually check in with harbor officials and pay attention to posted guidelines. That keeps wildlife safe and people out of trouble.
- Respect distance and don’t approach, feed, or try to touch the animal.
- Stick to designated viewing areas and public paths along the water in Sausalito, Larkspur, and Mill Valley.
- Bring a camera with a long lens, and a bit of patience too; mornings usually have calmer water for photos.
- Check NOAA advisories or local harbormaster updates before heading out from Marin’s ferry docks or waterfront parks in San Anselmo or San Rafael.
- Keep pets leashed and away from roped-off zones that protect the animals’ space.
Chonkers’ presence sparks a bigger conversation about how Marin County coexists with coastal wildlife. The sight lines between Sausalito’s houseboats, Tiburon’s ferry slips, and the San Francisco Bay shoreline always remind me that our ecosystem is a shared tapestry.
When these giants wander into our waters, Marin’s towns answer with a mix of awe, caution, and a kind of neighborly respect for the wild world that shapes life from the Marin Headlands down to the Embarcadero. Isn’t that just a little bit magical?
