Ausangate and Rainbow Mountain 4 days: the complete guide

10 min read Local Cusco team Updated February 2026

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.

Reaching Rainbow Mountain on foot means quiet and a real sense of arrival.

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.
