This four-day loop starting from Chachapoyas takes you into the Uctubamba Valley at altitudes in the region of 3 000m. The glaciated valley of Belén, through which the Río Huaylla meanders endlessly; medium-altitude hills in Gran Vilaya dotted with banana and coffee trees; thick vegetation that conceals ruins dating back to the time of the Chachapoyas; bird's-eye views from the Abra Yumal Pass, a look around the Kuelap Fortress... Your efforts will be richly rewarded.
