The park is comprised of diverse ecosystems that are spread out across extensive flatlands. These plains are blanketed with savanna vegetation and deciduous forests. The area is recognized as a vast tropical grassland plain locally known as a Llanos.
Additional ecosystems arise out of the abundant rivers, lagoons, and other waterways which give way to gallery forests, rainforests, and additional varied species of plant life. Although, the foundation of the park is grounded in the flat land of the plains, there are hills found within the park area.
The varied habitats provide an excellent opportunity for experiencing complementary diverse wildlife. The river is a habitat for river dolphins, river otter, and a wide variety of fish. Some of the popular species on land include the Onca tiger, the cougar, palmetto bear, giant armadillo, and a variety of monkeys.
There are a variety of bird species that add to the color and sounds of the picturesque landscape. The landscape also provides tremendous vegetation for grazing which is leveraged by ranchers who allow the cattle to feed.
The rainy season brings flooding and more challenges for enjoying the national park, whereas the dry season makes it easier to explore and increase the chances of seeing wildlife along the various waterways.
The park covers an area of 5,857 sq km making it the sixth-largest national park in the country.
