Ausangate and Rainbow Mountain 4 days: the complete guide
Most people see Rainbow Mountain on a crowded day trip. This four-day trek reaches it the way it deserves to be reached — on foot, across the wild Ausangate range, with glaciers, mineral lagoons and high passes, arriving at Vinicunca with hardly anyone else around.
Rainbow Mountain, earned on foot
You trek the flanks of Ausangate through glacial valleys and past coloured lakes, crossing high passes before reaching the famous striped ridge of Rainbow Mountain (5,020 m) — far from the day-trip crowds that arrive by bus.

Difficulty and altitude
A challenging high-altitude trek with several passes near 5,000 m. Acclimatize well in Cusco first. If you want the colours without the trek, compare the day options in our Palcoyo vs Vinicunca guide.
Two icons in one trek: Ausangate and Vinicunca
This four-day route is the smart way to combine the wild high-altitude scenery of the Ausangate massif with Rainbow Mountain (Vinicunca) — and to reach the famous striped ridge before the day-trip crowds arrive by bus. You hike past glacial lakes, cross passes above 5,000 m, sleep beneath 6,000 m peaks, and walk into Vinicunca from the trail side rather than the car park.
| Day | Highlight | Max altitude |
|---|---|---|
| 1 | Trailhead → glacial lagoons → camp | ~4,700 m |
| 2 | High pass beneath Ausangate | ~5,000 m |
| 3 | Red Valley → Rainbow Mountain | ~5,036 m |
| 4 | Descent and return to Cusco | — |
The Red Valley: Vinicunca's secret neighbour
Most Rainbow Mountain day-trippers never see the Red Valley (Valle Rojo), a sweep of iron-red hillsides just over the ridge from Vinicunca. On this trek it is a highlight of day three — a surreal crimson landscape you will often have largely to yourself. Combined with the rainbow ridge nearby, it makes for one of the most colour-saturated days of hiking anywhere in Peru.
How demanding is it?
This is a genuine high-altitude trek: you sleep above 4,600 m and cross passes over 5,000 m, with cold nights and thin air throughout. It rewards good fitness and, above all, thorough acclimatization in Cusco beforehand. It is shorter and a touch less punishing than the full 5-day Ausangate circuit, but it is not a beginner outing. Pack a warm sleeping system and read our altitude guide before you go.
Frequently asked questions
If you want quiet, scenery and a real sense of achievement, yes. The trek reaches Vinicunca away from the bus crowds, across spectacular Ausangate terrain.
Several passes approach 5,000 m and Rainbow Mountain itself is about 5,020 m, so thorough acclimatization is essential.
