Cotopaxi is an active stratovolcano in the Andes Mountains, located in the Latacunga canton of Cotopaxi Province, about 50 km (31 mi) south of Quito, and 33 km (21 mi) northeast of the city of Latacunga, Ecuador, in South America.
It is the second highest summit in Ecuador, reaching a height of 5,897 m (19,347 ft). It is one of the world’s highest volcanoes.
Since 1738, Cotopaxi has erupted more than 50 times, resulting in the creation of numerous valleys formed by lahars (mudflows) around the volcano. The last eruption lasted from August 2015 to January 2016. Cotopaxi was officially closed by the authorities to climbing until it reopened on October 7, 2017.
