Muir Beach, Marin County. This is a Bay Area classic: A crescent of sand bordered by high bluffs to the north and south, with wetlands and a lagoon behind the strand. Dogs under reliable voice control (meaning Daisy comes immediately when called) are allowed off-leash in designated areas.
Muir Beach is part of the Golden Gate National Recreation Area, which includes more than 12,000 acres of public land in Marin County. The possibilities for on-leash walks and off-leash beach frolics are many—and as a bonus, you’ll often be playing within view of the Golden Gate Bridge.
Upton’s Beach (adjacent to Stinson Beach, which doesn’t allow dogs), nearby Bolinas Beach, and Rodeo Beach in the Marin Headlands are among other dog-friendly Marin County strands.
