Of the 5 volcanoes in Isabela island, the Sierra Negra volcano is located at the southeast end of Isabela Island, close to Puerto Villamil port. It rises to a height of 1124 meters above sea level. It is one of the most active volcanoes in Galapagos with the most recent eruption in June 2018. It is a wonderful experience to reach the top, from where you can get to see all the volcanoes.
