Choquequirao ruins was most likely built during the reign of the Inca king Pachacuti Inca Yupanqui and is considered to be the last bastion of resistance and refuge of the Sons of the Sun, who fled from the city of Cusco when it was under siege in 1535. Led by Manco Inca Yupanqui, they took refuge in Choquequirao. Presumably, it was used both a check point to access the Vilcabamba Area and a cultural and religious center.
The city played an important role as it was a connection between the Amazon Jungle and the city of Cusco. The region has a lot of microclimates and a landscape full of snow-covered peaks of about 6000m (19685f). Choquequirao trek is the place where you'll discover the great citadel of the last inca kings and also you'll reach the beautiful ecosystem, Choquequirao trekking.
