Huayna Picchu, also referred to as Wayna Picchu or Wayna Pikchu, which means 'Young Peak' in Quechua, is the large mountain that sits directly behind Machu Picchu. For many trekkers, climbing Huayna Picchu is one of the highlights of a visit to Machu Picchu. This glorious site can be visited all year round, but the number of daily visitors is restricted, meaning that hikers are split between two entrance times. Hikers can choose between two trails of varying lengths, with the shorter trail taking approximately an hour to the summit while the longer about three hours to summit.
