A thick green tangle covering most of the Amazonian Trapezoid, the Amacayacu Natural National Park is a protected area situated south of Columbia on the bank of the Amazon River. Encompassing 293 500 hectares of swamps, marshes, madre-viejas, and river systems, this funnel-shaped forest is home to a teeming multitude of bird and mammal species, over 5000 species of plants, the largest diversity of primates in the world and 150 species of aquatic animals. Intrepid travellers can trek through the lush, unspoiled territory, walk along the winding forest canopy, visit Tarapoto Lake for the pink dolphins, and even enjoy a good day trip to Monkey Island.
