The ecoregion of Gran Chaco is the second largest contiguous forest in South America, after the Amazon. Thanks to the efforts of organizations and institutions dedicated to the conservation of nature, in 2011 an initiative was launched to create a National Park in Chaco, in the area occupied by Estancia La Fidelidad, a vast expanse of forest crossed by the Bermejo River and the Bermejito River.

The park protects 128 000 hectares with forests of palo santos, quebrachos and carob trees, grasslands, marshlands, lagoons, and endangered species, such as the giant armadillo, the giant anteater, the tapir, the maned wolf and, of course, the jaguar.

In 2014, El Impenetrable National Park was created although it was not until April 2017 that the Administration of National Parks could enter and guard the area.

In prehistoric times, the Chaco region where the National Park is located today was inhabited by communities of Pilagás, Mocovíes, Abipones, Chulupies, Chorotes, Mataras, Wichís and Quoms.

Towards the end of 1800, the area near the large rivers underwent another change of scale when it was occupied by Spaniards and Creoles, with some resistance from the native communities.

Today, in the areas surrounding the park, Creole families live side by side with Wichí settlements, located in reserves or community lands, such as Nueva Población, Nueva Pompeya and Wichí. The Quom communities have community lands to the southeast, in the Megasogochi Reserve, but they do not border the National Park.

This historical context has given rise to a rich diversity of knowledge and practices that visitors can learn about through the community-based tourism proposals that are being developed with great effort in the surroundings of La Armonía, at the main entrance to the National Park.
