At 6,384 meters (20,945 ft), Mt. Ausangate is the tallest peak in Cuzco and one of Peru's most difficult and beautiful climbs. Those with a taste for dizzying, uncrowded summits will revel in this experience, which takes adventure seekers on an epic journey over giant glaciers and around incredible glacial lakes (like Sibinacocha, the 22nd highest in the world) on trails that are largely empty and unregulated.
Hikers should expect to spend around 4-5 days circumnavigating the massif, with high passes topping out around 5,165 meters (16,945 ft). Feel like topping the mountain? It will require more time, money and risk, but for those unsatisfied with close enough it's an adventure well worth the cost. Just be sure you hire a knowledgeable guide, give yourself plenty of time to acclimate to the altitude, and don't miss out on a relaxing soak at the Upis hot springs on the way down.
