Cerro Cabrillo is one of the Nine Sisters, a group of nine volcanic landmarks in the area. Others include Morro Rock and Hollister Peak. It is named after Juan Rodríguez Cabrillo, a Spanish maritime explorer, who was sailing off the coast in 1542.
The rock outcrop, composed mostly of rhyodacite, is a volcanic plug formed when magma welled up underneath a layer of softer rock and solidified. The softer overlying rock has since eroded away leaving the distinct rugged shape. On its east face is a rock formation named Tiki Rock, because of its resemblance to a Polynesian Tiki carving.
The slopes and peak of Cerro Cabrillo are popular with hikers and rock climbers, with trailheads in Morro Bay State Park.
