Cerro Cabrillo, also known locally as Cabrillo Peak, is a rocky butte in Morro Bay State Park, California. 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.[3] It is one, in a group of nine volcanic plugs in the area known as the Nine Sisters, which includes Morro Rock and Bishop Peak. It is named after Juan Rodríguez Cabrillo, an explorer, who was in the area around 1542.
The peak is popular with hikers and climbers. Its slopes support many wild flowers such as Gentian, Deer Weed, Soap Plant, and Mallow. On its east side is a rock formation called a tiki because of its resemblance to a Polynesian carving.
