On the north side of Santiago Island the cliffs are made up of many layers of volcanic rock that gives it a wafer like appearance. In some areas it may look like a sairway into the deep. Cousin's Rock offers the opportunity to get close up with the sea lions and morays. Schooling hammerheads often visit thsi area so fi you get too foucsed on the many species of hawkfish and other small creatures among the endemic black corals, make sure you turn around and look up occasionally. You'll likely encounter turtles and might even get to see a manta ray behind the many clouds of creolefish and barracuda.
