Humadea

The Humadea River descends from the eastern Colombian Andes into the Llanos, contributing its waters to the upper Meta system. Mountain streams join on the foothill plain before flowing east through savannas and wetlands toward the Orinoco. Rainfall in the highlands can swell the rivers, while the plains experience a marked dry season. The river is one of several waterways connecting the mountain slopes with the extensive lowlands.

The later city of Villavicencio lies here.
