The massive basalt outcrop at Indian Joe Cave Rocks provides sport and challenge to rock climbers. Coast live oaks abound along with valley and blue oak, elderberry, madrone and gray pine. Spring brings wildflowers, including California poppies, mustard, goldfields and lupines, which carpet vast areas in yellow, orange and blue. A wildflower identification kit may be checked out at the Visitor Center. Observant campers and hikers may notice raccoons, skunks and blacktail deer.
Mountain lions are uncommon, but are occasionally sighted.
The acorn woodpecker, black phoebe, titmouse, turkey vulture and yellow-billed magpie are commonly sighted. A bird list is available at the Visitor Center. A description of park trails is found on the other side of this brochure. Please do not short cut trails in steep areas, or slide in the grass on hillsides or banks. Erosion is ugly and expensive to control.
