Discover the Guajará River, a tributary of the Amazon River with fast-flowing waters edged by a few dwellings. The place includes a pasture area for buffaloes and a narrow band of forest from which to observe sloths, green iguanas and myriad birds in stunning colours, such as the toco toucan. With a bit of luck, you might hear the loud cry of howler monkeys, since it can resonate over a radius of several kilometres. The river itself is renowned for being home to the famous pink river dolphin.
