Isla del Cerrito

Isla del Cerrito is a river island located where the Paraguay and Paraná Rivers meet in the Chaco region of Argentina. The terrain features forests, grasslands, and wetland areas typical of major river confluences in South America.

Brazil established a military base on the island during the War of the Triple Alliance from 1864 to 1870. In later decades, a medical center operated from 1924 until 1960, serving health needs for surrounding populations.

The island is home to communities that depend on fishing and cattle ranching for their livelihoods, shaping how settlements are organized along the waterways. These everyday practices reflect how local people have learned to live with the rhythms of two major rivers.

The San Pedro bridge is the main vehicle route connecting the island to surrounding areas through rural roads. The best time to visit is during the drier months when water levels are lower and roads are more easily passable.

A permanent waterway called Riacho Atajito divides the island, creating separate ecological zones with their own natural characteristics. This channel connects different sections of the island and influences how vegetation and wildlife are distributed across its territory.
