From Highway 156 turn onto Castroville Blvd.  Drive approximately 3 miles till the road meets a "T".  Go right (you're still on Castroville Blvd.)  Turn LEFT onto Elkhorn Road and drive just under 1 mile to Bayview.  Turn RIGHT onto Bayview and go over the hill until the road forks.  Stay to the RIGHT of the fork and you will be on Walker Valley Road.  All Creatures will be the 4th drive on the left hand side of the road.  Look for the big green sign.
