[4] Located in the region of the Llanos, it extends over the municipalities of Francisco de Miranda and Jose Rondon (formerly Las Mercedes) in Guárico state.

In 1974, the Venezuelan government, presided over by President Rafael Caldera, created the Aguaro-Guariquito National Park on an area of land located south of the Guárico State, in the jurisdiction of the municipalities Las Mercedes del Llano and Miranda.

It was therefore imperative that a sample of this natural formation be protected under the National Park regime, in order to preserve forever its original conditions for the benefit of present and future generations.

The climate is warm and presents two very marked seasons: the summer or drought, from November to March, the rainy or winter, which runs from April to October.

The Amazon river dolphin Inia geoffrensis can be found in the national park.
