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.

Geodesic point at the top of Coyote Ridge, with panoramic views across the Marin Headlands, with low brush offering views down toward the coast

Middle Green Gulch can be only used for uphill biking (and hiking either direction), not biking downhill! It arrives here at Coyote Ridge Trail just some 15 yards south of Green Gulch trail, which can be used to go downhill instead. Coyote Ridge is a wide gravel fire road, sloping down toward the coast.

Beautiful, quiet bay. With great surroundings. Not too crowded.

Simply a safe and fun multi use path, use it to connect to the Corte Madera creek path going north, or head south to hit Camino Alto for a bit of a climb up and over a hill to Mill Valley
