There’s a wonderfully open bird and wildlife sanctuary running along the east shoreline of Corte Madera with walking and cycling paths along the perimeter and down the middle along the old railway corridor.
It’s a 31-acre, wide open marsh, starting at the northern edge of the Mariner cove housing subdivision and continuing north until the Greenbrae Boardwalk along Corte Madera Creek. It’s bounded by the Bay on the east and San Clemente Drive and Redwood Highway on the west.
Dogs are welcome, but please keep them on leash, especially in the Spring with the young birds that are vulnerable to predators because they can’t yet fly!
