Tips from the Community
Corte Madera Town Park, originally at the western edge of tidelands that extended to the bay, was purchased by the Town in 1937 for $3,500. The 23 acres in the park had served as pastureland for the Meadowsweet Dairy in Corte Madera. The park provides a wide variety of updated recreational facilities serving both Corte Madera and Larkspur residents: Seven picnic areas each with one or two barbecues and two to four tables. These can be reserved in advance through the Corte Madera Parks and Recreation Department,(415) 927-5072 or recreation_dept@tcmmail.org.
