Fishing in Iguazu National Park

The park sits in the northeastern tip of Misiones Province, where the Río Iguazú runs through subtropical Atlantic Forest before meeting the Paraná system.

The park covers roughly 67,720 hectares on the Argentine side, and the river and its tributaries hold a native freshwater fauna that includes dorado (Salminus brasiliensis), surubí, pacú, manguruyú, boga, and armado.

The dorado is the fish most associated with this water. It runs golden and silver, built for fast current, and once hooked it jumps hard — the kind of fight that earns it the local name "tiger of the rivers."

Fish exceeding 20 kilograms have been recorded in the broader Paraná basin, though the Río Iguazú closer to the falls holds its own population alongside species like yacundá.

Fishing here happens inside a UNESCO World Heritage Site, which shapes the experience in ways that matter before you rig up. The park has its own entry requirements on top of whatever provincial or national licensing applies.

Check directly with Iguazú National Park administration for current permit requirements, any gear or access restrictions, and which waters are open — rules in protected areas change, and the park is the only reliable source for what's current.

The water itself is the context. The falls, the forest, the wildlife — they're not backdrop. They're the reason the fish are still here.
