The Lonely Planet guidebook calls Peru’s Amazon basin “the best-protected tract of the world’s most bio-diverse forest.” Puerto Maldonado (photos) is in the southern Amazon zone of Peru, due East of Cusco near the border with Bolivia. It sits at the confluence of Rio Tambopata and Rio Madre de Dios. The Rio Madre de Dios continues through Bolivia and into Brazil where it joins with the Amazon. There are a series of jungle lodges along the banks of this river downstream from Puerto Maldonado. We chose to spend 3 nights at the Eco Amazonia Lodge.
