A glacial lake formed by the retreat of the Salkantay glacier. Its turquoise colour comes from glacial sediment held in suspension.
The climb from Soraypampa is roughly two kilometres, with about 300 metres of elevation gain and a duration of around an hour and a half. It is short in distance but consistently steep, and takes place above 3,900 metres, so a steady pace from the outset is advisable.
Visitors commonly make an offering of coca leaves at the shore, following local custom. Swimming is not permitted: the water is glacial meltwater just above freezing, and the site is considered sacred.

Frequently asked questions
Is it easier than Rainbow Mountain?
It tops out 800 metres lower, so the altitude hits considerably less. But the gradient is steeper and more concentrated. A different kind of effort, not necessarily a lighter one.
Can I swim in the lake?
No. It is glacial meltwater just above freezing, and it is also considered a sacred site by local communities.
Is it good preparation for the Salkantay trek?
Yes — it is the same area and a very good gauge. If this climb felt manageable, the multi-day trek is realistic for you.
When not to go: January and February — the trail gets very muddy
