Fishing in Parque Nacional El Palmar

Parque Nacional El Palmar sits on the center-east of Entre Ríos province, roughly midway between Colón and Concordia, where the land rolls gently from palm-studded savanna down to the Uruguay River.

The park's 85 km² hold a mosaic of grassland, small woodland patches, and wetlands cut through by streams that drain eastward into the Uruguay. That river forms the park's eastern boundary, and the streams feeding it are where most of the fishing happens.

The arroyos are the defining waters here. Arroyo Los Loros, Arroyo del Medio, and Arroyo Ubajay are the named streams inside the park, threading through palm savanna before reaching the Uruguay.

These are typical Mesopotamian lowland streams — slow to moderate, with vegetated banks and the kind of structure that holds warmwater species. The Uruguay River itself runs along the park's edge and is accessible from the camping area near the river.

Before you fish, contact the park directly.

The Administración de Parques Nacionales governs El Palmar, and you should confirm with them what permit is required, which waters are open, and what rules apply inside the protected area — these can differ from the provincial fishing regulations that apply outside the park boundary.

The park's contact for visitor questions is available via WhatsApp at +54 9 3447 42-7930. Access to the water is straightforward on foot or by vehicle along the park's gravel roads, which connect the main points of interest.

Kayaks can be brought in, which opens up the river frontage and the lower reaches of the arroyos to anyone who wants to cover more water quietly.

El Palmar is not a destination built around fishing — it was created to protect the yatay palm ecosystem, and that context shapes the experience. The streams are there, the river is there, and the fishing can be good.

But you're working within a conservation framework, which means checking the rules before you go matters more here than it does on open water.
