Most visitors see Rainbow Mountain as a single, crowded day trip from Cusco — buses arrive before dawn and the viewpoint fills within an hour of sunrise. The full Ausangate circuit takes in the same striped slopes of Vinicunca, but as the final act of a five-day trek around one of Cusco’s most sacred mountains, reaching the viewpoint from the quieter side of the massif and largely ahead of the day-trip crowds.
Ausangate itself, at 6,384m, is revered in Andean cosmology as an apu — a mountain spirit — and the circuit around its base crosses two passes above 5,000m, higher than anything on the Inca Trail, Salkantay, or Lares routes. The reward is a landscape unlike the rest of the region’s Inca-ruin-focused trekking: turquoise and rust-red glacial lakes, herds of alpaca grazing at extreme altitude, and hot springs at Upis to soak in after the first day’s approach.
This is genuinely demanding, high-altitude trekking, and prior acclimatisation in Cusco is essential rather than optional — the trek’s lowest campsite still sits above 4,400m. For trekkers who’ve done the Inca Trail or Salkantay and want something wilder and higher, this is the region’s standout choice. April through October offers the clearest pass crossings and the best chance of a cloud-free Rainbow Mountain view.
