Bartolomé Island is a volcanic islet in the Galápagos Islands group, just off the east coast of Santiago Island. It is one of the "younger" islands in the Galápagos archipelago. This island, and Sulivan Bay on Santiago island, are named after naturalist and lifelong friend of Charles Darwin, Sir Bartholomew James Sulivan, who was a lieutenant aboard HMS Beagle.
With a total land area of just 1.2 square kilometres, this island offers some of the most beautiful landscapes in the archipelago. The island consists of an extinct volcano and a variety of red, orange, green, and glistening black volcanic formations.
