Antisana

Antisana is a stratovolcano of the northern Andes, in Ecuador. It is the fourth highest volcano in Ecuador, at 5,753 metres, and is located 50 kilometres SE of the capital city of Quito.

Antisana presents one of the most challenging technical climbs in the Ecuadorian Andes. Next to the Pichincha, Cotopaxi, Tungurahua and Chimborazo, the Antisana belongs to the five volcanic mountains that the Prussian-born explorer Alexander von Humboldt tried to climb in 1802 during his American journey.
