Porpoises are Back in San Francisco Bay After Decades Away, and the Best Place to See Them is From the Golden Gate Bridge

When William Keener got a report of a harbor porpoise inside San Francisco Bay in 2008, he knew this was big news: They had been absent since World War II. Now, Keener’s group of researchers has turned the Golden Gate Bridge into a world-class wildlife observatory where anyone can see porpoises in action. Why have they returned? Did Bay cleanup efforts make the difference? While we can’t know for sure, we can celebrate this rare case of a large mammal reintroducing itself into its former habitat.

Paddling on the Wild Side

Few craft can match a kayak for allowing you to immerse yourself in the watery universe of bay or ocean, moving silently through the world of seals, otters, dolphins, and seabirds. Two of our region’s most experienced sea kayakers take us out on the water for up-close and personal encounters with some of the bountiful and charismatic marine life plying our local marine habitats.
