Puerto Egas, south of James Bay and west side of Santiago, is one of the best sites. There is a long, lava shoreline where eroded rock formations house an excellent variety of wildlife. Marine iguanas bask in the sun. The tide pools contain many Sally Lightfoot crabs, which attract other types of hunters. Following the trail Fur seal lions are found. Puerto Egas is not only a good spot for taking pictures but also perfect for snorkeling and seeing many species of tropical fish.
Sullivan Bay is especially fascinating for those who are interested in geology and volcanology. You can walk over the uneroded, black lava flow covered with lava bubbles and tree-trunk molds in the surface. There are two small beaches where turtles come for nesting.
Cousin's Rock is a well-known dive site and is situated off the east coast of Santiago. It is a triangular rock that rises about 10 m out of the water and is made up of many layers of volcanic rock.
Sombrero Chino is a small islet off the southeastern tip of Santiago. A 52-meter-high, 0.22 km2 volcanic cone, it is named for its resemblance to the conical Asian hat.
