Mountain of 7 colors of the Andes
Vinicunca is a mountain pass located about a four-hour drive southeast of Cusco city, in the opposite direction of Machu Picchu, Inca Trail, and the famous Humantay Lake. Known more commonly by locals as La Montaña de Siete Colores(mountain of seven colors) and by travelers as the Rainbow Mountain Peru or Cerro Vinincunca, the geographical wonder is famous for its rainbow tonality- a surreal natural phenomenon of mineral deposits streaked across sandstone rock.
