3 days
The essentials
For travellers passing through Cusco as part of a longer trip around Peru.
Day 1
Cusco City TourIn the afternoon. The morning goes on arriving and doing nothing, which is part of the plan.
Day 2
Sacred Valley of the IncasThe valley sits lower than Cusco and helps you acclimatise.
Day 3
Three days leaves no room for a high mountain: Rainbow Mountain and the glacial lakes are above 4,200 m and without acclimatisation they are miserable. Do not book your outbound flight for day 3 either — the tour gets back to Cusco around 21:30.
