Deep in the dry Chaco, near the Bolivian border, this park of some 42,000 hectares protects dense, thorny forest of white quebracho, samu'u, guayacán and palo lanza, with cacti everywhere. Trails walked with the rangers lead to old military tracks and Chaco War trenches, and the wildlife (jurumi, or giant anteater, taguá, mborevi and Chaco chachalaca) reveals itself to the patient at dawn. It has a camping area and is easier to reach than other parks in the northern Chaco.

It was created on May 21, 1980 by Decree 15,936. Within the park, military tracks and trenches from the Chaco War (1932-1935) have been preserved. With so few people living nearby it faces little direct pressure, although its buffer zone is being degraded by extensive cattle ranching.
