Morro Rock (Salinan: Le'samo; Chumash: Lisamu'; Spanish: El Morro)[4][5][6] is a volcanic plug in Morro Bay, California, on the Pacific Coast at the entrance to Morro Bay harbor. A causeway connects it with the shore, making it a tied island. The rock is protected as the Morro Rock State Preserve.[7]
