A first-timer's guide to the Ausangate trek
The Ausangate trek is Peru's most spectacular high-altitude circuit — turquoise lakes, glaciers, herds of alpacas and the famous Rainbow Mountain, all above 4,000 m. It is also demanding. If it is your first big Andean trek, this is what you need to know to arrive ready and actually enjoy it.
What to expect
Ausangate circles a sacred 6,384 m glaciated peak. You will camp high, cross passes above 5,000 m, and walk through some of the most remote, dramatic scenery in the Andes — often without seeing another group for hours. Many versions also fold in Rainbow Mountain (Vinicunca), reached the quiet way, from the trail side rather than the day-tripper side.
How hard is it, really?
Honestly: it is challenging, mainly because of altitude, not technical difficulty. There is no climbing or scrambling, but you walk long days at heights where the air holds far less oxygen, and nights are genuinely cold.
| Factor | Ausangate |
|---|---|
| Max altitude | ~5,000–5,200 m passes |
| Daily walking | 6–8 hours |
| Terrain | High trail, no technical climbing |
| Main challenge | Altitude and cold nights |
| Fitness needed | Good — train beforehand |
How to prepare as a first-timer
Three things matter most. Acclimatize: spend at least two to three days in Cusco (3,400 m) and ideally a warm-up day trip before you start. Train: build leg and cardio fitness with hills in the months before. Pack for cold: nights drop well below freezing. Our Andean packing guide applies directly.

When to go and which version to pick
The dry season (May to September) is best for stable weather and clear glacier views, though nights are coldest then. For a first attempt, choose a version with a sensible acclimatization buffer and consider the Ausangate + Rainbow Mountain route if you want both icons in one trip. Whatever you choose, do not skip the acclimatization days — they make or break this trek.
Frequently asked questions
It suits fit first-time trekkers who prepare properly. There is no technical climbing, but the high altitude and long days make acclimatization and cardio fitness essential.
The circuit crosses passes around 5,000 to 5,200 m, with camps at very high altitude. The namesake peak rises to 6,384 m.
Many versions do. Reaching Vinicunca from the trail means you see Rainbow Mountain away from the day-tripper crowds, often early and quiet.
The dry season from May to September offers the most stable weather and clearest views, though nights are very cold. Always build in acclimatization days first.
