Souza Rock is an offshore pinnacle on the Central Coast between Port San Luis and Morro Bay. Its top sits at about 6 m (20 ft) below the surface and its base lies near 37 m (120 ft), so one dive can run from a shallow summit down to depths that call for deep training. It is reached by small boat from the Port San Luis or Morro Bay launches.
