About Millbrae Crescent Wetlands

Millbrae Crescent Wetlands is a critical coastal marsh ecosystem in San Mateo County, California, providing rich habitat for waterfowl and native wildlife alongside accessible nature trails for outdoor enthusiasts.

Wilderness Landscape & Natural Heritage

Millbrae Crescent Wetlands is a coastal wetland located along the San Francisco Bay in Millbrae, California. This restored wetland area plays an important role in supporting local biodiversity by providing habitat for numerous waterfowl species, shorebirds, and other wetland-dependent wildlife. The geography of the wetlands consists primarily of tidal marshes and mudflats that fluctuate with the tides, contributing to a dynamic ecosystem that absorbs runoff and improves water quality. Historically, the area was heavily altered by urban development and fill operations during the 20th century but has since undergone significant restoration efforts spearheaded by local agencies and conservation groups. Visitors to Millbrae Crescent Wetlands can enjoy a well-maintained trail system that offers opportunities for birdwatching, photography, and low-impact walking. Signage along the pathways educates visitors on the wetland’s ecology and the importance of preserving shoreline habitats. The proximity to the San Francisco Bay Trail provides connections for longer hikes or bike rides along the bay. Though the site is relatively small compared to larger nature reserves, it serves as a vital green space for urban residents and acts as a critical stopover for migratory birds on the Pacific Flyway. The wetlands also provide educational opportunities for schools and community groups focused on environmental stewardship and coastal ecology. Overall, Millbrae Crescent Wetlands offers a peaceful natural refuge with accessible outdoor recreation combined with valuable conservation significance in a rapidly developed region.
