Rainbow Mountain, or Vinicunca as it’s known by locals, has become a popular hike in the Cusco region. It’s possible to visit Rainbow Mountain in one (very long) day from Cusco or you can divide the trip into a two-day itinerary. While the hike isn’t very difficult and doesn’t have many steep inclines, Vinicunca is in a high elevation region (the highest part of the trail is 17,060 ft or 5,200 m) and you should spend time acclimating before starting the hike.
