The Rio Azul is a river located in the extreme south of the state of Pará, Brazil, within the Amazon biome. It flows through the Serra do Cachimbó region. The primary access point for visitors is via the Rio Azul Jungle Lodge, a family-operated facility near Novo Progresso. Reaching the lodge and the river requires significant travel, approximately 3 to 4 hours from Alta Floresta, including a boat transfer from Cristalino Jungle Lodge to the Teles Pires boat launch. The lodge serves as a base for exploring the surrounding area, offering guided access to the river and its environs via trails, old logging roads, and farm roads. The river's name, "Azul," meaning "blue," suggests a clear or aesthetically pleasing water color. The region is noted for its rich biodiversity, making wildlife observation a key feature of any visit. The area provides access to several important Amazonian habitats, attracting birders and naturalists. The overall character of a paddling trip here would be a remote, immersive Amazonian experience focused on nature and wildlife, rather than a developed recreational corridor. Paddling is not restricted.
