Fishing in Campos Amazônicos National Park

Campos Amazônicos sits across parts of Amazonas, Rondônia, and Mato Grosso — nearly a million hectares where the Amazon rainforest grades into cerrado savanna. The terrain is mostly flat to gently rolling, laced with slow, meandering rivers.

The park contains headwaters and upper drainages, not big navigable mainstems, which shapes the character of the fishing throughout.

The Roosevelt River runs through the park from south to north, and the Jiparaná (Machado) River forms the southern boundary in Rondônia.

Inside the park, the named waters are largely igarapés — the small blackwater and clearwater streams that feed the larger systems.

Igarapé Preto, Igarapé São Domingos, Igarapé Jatuarana, Igarapé Sucuri, Igarapé dos Marmelos, and Igarapé da Taboca are among the drainages within the park's boundaries, along with Rio Madeirinha, Rio São João, and Rio dos Macacos.

The park also contains headwaters of the dos Marmelos and Manicoré rivers. These are intimate, shaded waters — the kind where you're fishing structure and reading current seams rather than covering open water.

The park is classified as Proteção Integral — strict protection — and administered by the Chico Mendes Institute for Biodiversity Conservation (ICMBio).

That designation matters for anyone planning a trip: all extractive and commercial activity is prohibited within the park.

Before making any plans to fish here, contact ICMBio directly to understand what, if any, recreational fishing is permitted and what authorizations apply.

Rules in strictly protected Brazilian federal parks can differ significantly from what's allowed in extractive reserves or state forests nearby. Access is remote.

The nearest city is Machadinho d'Oeste in Rondônia, and the park borders the Trans-Amazonian Highway (BR-230) to the north in Amazonas. Getting to the interior waters means serious logistical planning — this is not a park with developed visitor infrastructure.

The cerrado enclaves within the park add an ecological dimension you won't find in most Amazonian drainages.

Headwater streams flowing through savanna-forest transitions can hold different conditions than those running through closed-canopy rainforest, and the park's position within the Southern Amazon Conservation Corridor means these watersheds remain among the least disturbed in the region.

That integrity is worth protecting — and worth understanding before you go.
