Walnut Creek Open Space – Shell Ridge

Shell Ridge is 1,421 acres of protected open space and trails with rolling hills, creeks, coast live, valley, blue and black oaks, and historic structures that include the Borges Ranch and Howe Homestead Park in the City of Walnut Creek, CA. With proceeds of a bond issue authorized by the citizens in 1974, the City bought and preserved the undeveloped Acalanes Ridge, Lime Ridge, Shell Ridge and Sugarloaf Open Spaces. The largest of the four—Shell Ridge—has roughly 1,420 acres of oak woodlands and grassland savannah and 31 miles of trails.
