Fodor's Expert Review Los Amigos Biological Station

Though farther from the Tambopata National Reserve than the other lodges, this off-the-beaten-path biological station lies within a 1,119-acre private reserve that holds most of the same wildlife, including giant river otters, 11 primate species, and more than 550 bird species. Simple bungalows with private baths and porches stand in a clearing in the jungle together with the biological station's laboratories, dorms, and dining hall. Daily excursions include rainforest hikes and floats through a palm swamp and an oxbow lake. The lodge can only be visited on a five-day tour.
