Fishing in Viruá National Park

Viruá sits in the lowland basin of central-southern Roraima, where the campinarana — white-sand forest on poor, acidic soils — floods seasonally across nearly 242,000 hectares.

The park's hydrology is shaped by two large rivers on its boundaries and a network of smaller blackwater channels threading through the interior.

That seasonal pulse, driven by the Rio Branco to the west, is what defines the fishing here: water levels shift dramatically between wet and dry, and the fish move with them.

The Rio Branco forms the park's western boundary, and the Rio Anauá runs along its southern limit. Both are significant rivers in their own right, and the Anauá feeds into the Branco just outside the park's edge.

Inside the park, the Igarapé Viruá — a blackwater river carrying little sediment — drains southward into the Anauá. These blackwater systems carry the tannin-stained, low-conductivity water typical of white-sand Amazon drainages.

The Igarapé Curumi is among the smaller interior channels accessible to visitors. Fishing is permitted in the park's waters, subject to current state and federal regulations.

The ICMBio page for Viruá states explicitly that fishing is allowed while respecting applicable state and federal norms — check directly with the park administration for what that means in practice before you go, as rules can be updated.

Access to the park runs via the Estrada Perdida, roughly two hours from Boa Vista. The park is open daily.

The seasonal flooding that defines the landscape also defines access: during high water, vast areas become temporary wetlands, and reaching interior igarapés by boat becomes possible where it isn't during the dry season. Plan around that cycle, not against it.

This is remote Amazonian fishing in a functioning protected area. The infrastructure is minimal, the biodiversity is genuinely high, and the water does the work of telling you where to be and when.
