Santiago, also called James Island, is located in the western-central part of the Galapagos archipelago. It is the fourth largest island in the archipelago (following Isabela, Fernandina and Santa Cruz). Along with some of the large western volcanoes of Isabela and Fernandina, Santiago is also volcanically active, with many young flows and cones to be seen, particularly along the southern, western, and eastern coasts. These can even be seen from the summit of Darwin Volcano and from space. A number of large eruptions have been reported over the last 2 centuries. Santiago actually consists of two coalesced volcanoes: a typical shield volcano on the northwest end and a low, linear fissure volcano on the southeast end.
Bartolome Island is situated across Sullivan Bay. It has an altitude of 114 meters, from where we can observe one of the most beautiful sceneries of the Galapagos Islands such as: Volcanic cones, lunar-like craters, lava fields, and the famous Toba formed pinnacle eroded by the sea. There is very little vegetation on this island.
It has two breathtaking beaches where marine turtles exist and at the base of the pinnacle, as well as a very small colony of Galapagos penguins.
