Camping Cascallares sits along the Río de la Reconquista, downstream from the Dique Roggero in the Buenos Aires province.

The area is considered one of the least polluted stretches of the entire Reconquista river system, and fishing is a common activity along its banks.

The Cascallares name traces back to 1847, when Antonino Tadeo Cascallares purchased a large tract of land fronting the Río de la Reconquista in what is now the Partido de Marcos Paz and Mariano Acosta.

The site has a long recreational history — in the first half of the twentieth century, the Cascallares riverbank was a popular summer destination for local residents.

Today the campground remains a well-known spot in the region, drawing visitors who come to fish and enjoy the natural surroundings along the river.
