For a different dive venue with artificial reefs, consider chartering a boat to take you to one of the 25 oil platforms between Santa Barbara and Huntington Beach. Several miles from shore, you can see mola mola (ocean sunfish), sheepshead, rockfish, sharks, barracuda, rays, sardines, and mackerels, as well as sea lions, jellyfish, and more. You may encounter surges and currents that are mild to strong, limited visibility, and cold thermoclines. You should also have an experienced divemaster with you, as well as flashlights.
