The Rio Xingu is a major tributary of the Amazon River, flowing through the state of Pará in northern Brazil. It is characterized by distinct sections, with its upper course marked by innumerable rapids, while the river is navigable from its mouth upstream to the towns of Sousel and Vitória, a distance of approximately 125 miles. This navigable section offers the primary paddling opportunities. The river's middle section, located in Pará, is part of the broader Amazon Basin. Guided kayak tours are available, such as those offered by Xingu Caiaques based in Altamira, which provide private tours on the river and trips along regional trails. The overall character of the river is significant, being one of the longest Amazon tributaries and a focus for hydroelectric development. The area holds considerable ecological and cultural importance, supporting artisanal fisheries documented by thousands of fishing trips and being home to indigenous communities. For paddlers, the key considerations are the presence of rapids in the upper reaches, which dictate where navigable sections begin, and the river's role as a vital waterway within the Amazon rainforest ecosystem.
