Cousins Rock is one of the most popular dive sites in the Central Islands. The triangular islet, formed of volcanic tuff, is located to the west of the coast of the island of Santiago. This site is frequently frequented by diving cruises.  The region’s dive sites are characterized by their eroded surfaces covered with soft corals and gorgonians. Highlights include nudibranchs, frogfish, seahorses, sea lions, eagle rays and schools of fish. This islet has a depth varying from 10-90 feet (3-27 m), with a slope descending to more than 140 feet (40 m). This site can also be visited as a daily outing, but the boat trip takes up to 2 hours.
