Located on plains that roll on for hundreds of miles south and east of the Andes, Los Llanos is an area of flat, mostly open cattle ground, punctuated with some isolated stands of gallery forest. During the latter part of the rainy season (July-Nov), the plains are almost entirely flooded, with only a few raised highways and service roads passable in anything that doesn't float. In the dry season, the land reemerges and wildlife congregates in dense herds and mixed flocks around the ponds and creeks left behind. Traditionally agricultural land, Los Llanos has also garnered fame as a destination for wildlife lovers and bird-watchers.

The quantity and variety of wildlife visible at the nature lodges located in Los Llanos is phenomenal -- anaconda, caiman, capybara, deer, massive flocks of birds, and even wildcats are commonly sighted.
