Santiago Island is an island of the Galápagos Islands. It is also known as San Salvador, named after the first island discovered by Columbus in the Caribbean Sea or as James Island. The island, which consists of two overlapping volcanoes, has an area of 585 km² and a maximum altitude of 907 meters, atop the northwestern shield volcano. The volcano in the island's southwest erupted along a linear fissure, and is much lower. The oldest lava flows on the island date back to 750,000 years ago.
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 while land iguanas scatter around feeding on exposed algae. The tide pools contain many Sally Lightfoot crabs, which attract other types of hunters. Sources
