Fishing in Parque Nacional Montanhas do Tumucumaque

The rivers draining Parque Nacional Montanhas do Tumucumaque run off the ancient Guiana Shield in the far north of Amapá and Pará, threading through nearly 39,000 square kilometers of intact Amazonian forest before reaching lowland Brazil.

The park sits against the borders of French Guiana and Suriname, and its watersheds feed systems that flow both north and south. Access is by river, and the rivers themselves are the roads.

The Rio Amapari is the practical entry point for most expeditions — the ICMBio base at Serra do Navio sits just outside the park, and boats travel upriver from there into the interior.

During dry season the Amapari runs low enough that even light voadeiras have to pick their lines carefully through the shallows.

The Rio Jari drains the park's southern reaches toward Laranjal do Jari, while the Rio Cassiporé and Rio Anotaié drain toward the northeast near Calçoene and Oiapoque.

The Rio Araguari, Rio Mutura, Rio Mutum, Rio Uassipein, and smaller igarapés — including Igarapé Muipi, Igarapé Mulini, Igarapé Pracassoca, and Igarapé Ximim-Ximim — lace the interior, most of them reachable only after days of river travel or on foot.

Fishing inside the park is tightly restricted. The park's governing documents note that hunting and fishing occur only at specific, limited points within the unit, and that fishing directly affects the animal populations being exploited.

This is a protection-integral conservation area managed by ICMBio, not a recreational fishery. Anyone planning to fish here needs to contact ICMBio directly — the park administration can be reached at tumucumaque@icmbio. gov.

br — to understand what is currently permitted, where, and under what conditions. Do not assume access or permission. The forest here is genuinely remote. There is no cell signal past Serra do Navio.

Expeditions require days of travel by boat and on foot, and the logistics of moving gear on low-water rivers demand experience and local knowledge. The waters are intact precisely because almost no one reaches them.

That's worth keeping in mind before you go, and worth protecting once you're there.
