The forest may be accessed by land via BR-163 and BR-230, the main federal highways in the region, or by boat via the Tapajós and Jamanxim rivers, and tributaries such as the Igarapé do Botica and the Ratão.

The Jamanxim, which rises in the Serra do Cachimbo in the extreme south of the state, has fast-flowing passages and areas where it sprawls into backwaters, making travel by large boats difficult along most of its length.
