Today we get ready to explore the most amazing archipelago in the Pacific coast and the place where Charles Darwin based his theory on the evolution of species. Once we arrive, we head to the town of Puerto Ayora, the largest town in the Galapagos. Then we move to the largest island in the archipelago and where most of the volcanic activity in the Galapagos is reported. Isabela Island was formed by six shield volcanoes, Alcedo, Cerro Azul, Darwin, Ecuador, Sierra Negra and Wolf; five of them are still active which makes the island one of the most volcanically active places on earth.
