About this campground
Where the San Francisco Bay meets rolling hillsides, Dumbarton Quarry Campground transforms 45 acres of reclaimed industrial land into an outdoor enthusiast's basecamp. With 63 thoughtfully designed campsites—including full-hookup RV spots and two secluded tent-only havens—this unique destination places you at the crossroads of wetland wonders and grassy hill country. Miles of hiking and biking trails branch out from your doorstep, inviting exploration of this remarkable Bay Area landscape.
The campground offers RV sites with full hookups and two designated tent sites. All RV sites feature concrete pads, 50-amp electricity, water, and sewer hookups, while the tent sites are unpaved and have access to water. Group camping and cabin lodging are not available.
Historical SignificanceThis land tells a story of transformation. For six decades, the Dumbarton Quarry carved deep into the earth, ultimately creating North America's deepest human-made pit—a testament to industrial ambition. Today, nature has reclaimed this space, turning scars into sanctuary. Just a short journey away, the Coyote Hills Visitor Center preserves an even older narrative, sharing the rich heritage of the Tuibun Ohlone people who called these baylands home for thousands of years.
Weather and SeasonsThe Bay's maritime influence creates a microclimate of contrasts here. Expect refreshing breezes that keep summer temperatures surprisingly cool—perfect for active adventures without the swelter. Winter brings occasional rain showers that green the hillsides, while the campground's signature winds carry the salt-sweet scent of nearby marshlands year-round. Pack layers and embrace the elements that make this coastal camping experience so distinctive.

Natural Features and SceneryPerched between two of the Bay Area's most treasured natural spaces, the campground offers front-row seats to an ecological theater. To one side, the Don Edwards Wildlife Refuge spreads its tapestry of tidal marshes and mudflats, alive with the calls of migrating birds. On the other, Coyote Hills Regional Park rises in gentle waves of golden grass, punctuated by ancient willow groves. This convergence of ecosystems creates ever-changing vistas—from misty morning wetlands to sunset-gilded hillsides.
Geological RegionNestled along the southern East Bay shoreline, this campground occupies a fascinating geological transition zone where ancient bay sediments meet uplifted marine terraces. The surrounding landscape showcases the dynamic forces that shaped the San Francisco Bay—from the wetlands that filter and protect these waters to the weathered hills that once lay beneath prehistoric seas. It's a living classroom of California's geological heritage, where every trail reveals another chapter in the earth's story.
