Actually, Cusco has three rainbow mountains; the last one was discovered during the COVID-19 pandemic. These three rainbow mountains are: Vinikunca, the classic and most visited; Palccoyo, which is a great alternative for those who do not like the crowded areas; and Pallay Punchu, which also offers stunning views. If you want a challenging trek with breathtaking views, then the Vinicunka Rainbow Mountain is what you are looking for.
