The Galapagos Islands are a volcanic archipelago in the Pacific Ocean. It is known as one of the most famous destinations in the world for wildlife watching. It is a province of Ecuador and is located about 1,000 km from its coasts. Its secluded terrain is home to a diversity of animal and plant species, many of them unique. Charles Darwin visited it in 1835, and his observation of Galapagos species later inspired his theory of evolution.
