Larkspur hugs the foothills of Mt. Tamalpais along Corte Madera Creek and the adjacent floodplain. Charming Magnolia Avenue, with restaurants, galleries and shops, is Larkspur’s main shopping strip and connects the town its next-door neighbor, Corte Madera. The two towns share the same police and fire departments, elementary school district, and little league and are jointly known as the Twin Cities. Larkspur’s neighborhoods are mostly wooded and a mix of old summer cottages, some quite stately homes, and mid-century modernism in all its forms. The eastern part of town extends to the bay side of Highway 101 and includes multi-unit housing in the form of condominium and rental apartments within walking distance of ferry service to downtown San Francisco.
Larkspur shares the Larkspur-Corte Madera School District with its next-door neighbor and is part of the Tamalpais Union High School District. It is the home of Redwood High School.
