PERU TRAVEL
We take a 11 hour bus trip from the city of Cusco ascending to the high mountain area at 4200 m (14,000 feet). After a short stop in Ninamarca, to see the pre-Inca cemetery, and Paucartambo village, we descend the eastern slopes of the Andes through cloud forest with lush vegetation (ferns, orchids, etc.) to the lowland rainforest on the Madre de Dios and Manu Rivers.
