Richardson Bay, Protected bay in Marin County, California.
Richardson Bay is a shallow protected bay in Marin County that spreads across a large area and features extensive eelgrass beds and intertidal habitats. The water depth and channel structure shape the appearance of this natural water body.
The bay was named after William Richardson, who established an early trading post residence in this area in the early 1800s. This early European presence shaped the subsequent development of the Marin County region.
The National Audubon Society manages a 369-acre sanctuary within Richardson Bay, supporting environmental education and conservation programs.
Visitors can best explore the bay by kayak or small sailing boat, as the shallow waters do not accommodate larger vessels. Several access points along the shoreline allow people to enter the water easily.
The seafloor of this bay contains sediment layers that document geological changes over long periods of time. These layers tell the story of the San Francisco Bay region from a natural perspective.
