About Tiburon

Tiburon is a small historic town in California's Marin County, located across the bay from San Francisco. Tiburon's Main Street has been preserved as it was when the town was a Gold Rush train town and lumber yard. The scenic "Ark Row" shops are actually housed in turn of the century boat houses that were converted into homes and shops when the lagoon between the Tiburon peninsula and the neighboring island of Belvedere was filled in.
