Shell Ridge is the City of Walnut Creek's largest open space unit, with trails for biking, hiking and riding through oak woodlands and grassland savannah on the lower flanks of Mount Diablo. Shell Ridge gets its name from the marine fossils left behind when the ocean waters that once covered the area receded.
Well behaved dogs are welcome, but please note: Rangers recommend dogs remain leashed at all times. If they are off leash, dogs must be under positive sight and voice command.(please keep in mind there is abundant wildlife in the area, including coyotes, as well as cattle)
