Illiniza is a stratovolcano in Ecuador, located about 55 km (34 miles) southwest of Quito. Illiniza consists of two snow covered peaks: Illiniza Sur (5.248 m) and Illiniza Norte (5.126 m).
Illiniza Sur is a more difficult climb due to its glacial nature, Illiniza Norte is a trekking peak. A guide is still recommended, since the path becomes hard to navigate as it approaches the summit (also the weather changes quickly). Boriss = High Andean recommended Segundo, his friend (Boriss was busy with another client).
It is a great acclimatization peak in Ecuador.
