The hook
A construction landfill that turned into an unofficial sculpture park, out on a spit in the bay.
01Why it's worth it
The whole peninsula is concrete rubble and rebar, dumped here until the 1980s. Artists moved into the debris and never really left, so the paths run past driftwood sculptures, spray-painted slabs of old freeway, and installations that wash into the bay and get rebuilt. For years people lived out here and made most of the work, until the city cleared the camp in 2014 to turn the Bulb into a park. Nothing has a plaque, it's rubble underfoot, and it looks different every visit. That churn is the appeal, so don't come expecting a finished, tidy art walk.
02How to experience it
Park at the end of Buchanan Street, follow whatever path looks interesting toward sunset, and take the unmarked trails down to the water where most of the art hides.
03Skip the cliché
Skip the manicured Cesar Chavez Park next door in Berkeley. The Bulb is the one with anything to say.
From the locals
East Bay regulars keep it quiet and protective, and tell you to go at golden hour and expect it to look nothing like the photos.
