About San Rafael/Larkspur

The largest city in Marin County, San Rafael is idyllically situated between San Francisco and the wine country. Home to China Camp State Park and Lucas Valley Preserve, and nestled at the foot of Mount Tamalpais, the area offers abundant outdoor recreation opportunities. Central Marin benefits from its proximity to San Francisco and offers a premier suburban lifestyle and excellent public school system.

The new SMART light rail train runs from the Sonoma County Airport throughout San Rafael to the Larkspur Ferry terminal, which provides daily service for San Francisco-bound commuters. U.S. Route 101 is the main artery for travel in the North Bay and provides access into San Francisco and north to Santa Rosa. The San Rafael-Richmond Bridge connects to the greater East Bay and Sacramento beyond.

Local professional service providers, several mature technology firms, and a growing hub of biotechnology-life science companies operate in the neighborhood, such as BioMarin Pharmaceutical, which employs more than 2,000 in San Rafael. Employers are attracted to the area’s highly educated workforce and affordability compared with San Francisco. Both residents and workers appreciate the neighborhood’s intangible benefits, from natural landscapes to quality public education.
