This park, which is situated in the outermost corner of El Chaco, is the largest and most inaccessible park in the country. Yet, it is the place in all of South America that offers the greatest opportunity to see jaguars, pumas and other big catlike carnivores. The forest is very dense and in some places completely impassable. It is always possible to navigate by the top of Cerro Leon, a mountain which is 500 meters high and offers a break from the otherwise flat landscape.
