Arauca River, Western tributary river of the Orinoco River in Colombia and Venezuela.
The Arauca River is a tributary of the Orinoco that flows approximately 800 kilometers from the Cordillera Oriental in the Andes through Colombia and Venezuela. The waterway remains navigable along most of its course, connecting settlements across both countries.
The river took its name from the Araucana people who lived in the mountains near its source before colonial times. The name preserves the memory of the indigenous groups that inhabited this region long before European arrival.
People living along the river have fished and farmed the land for generations, shaping how communities organize their daily lives. These practices connect residents directly to the water and soil that sustain them.
The river is easiest to explore during the drier months when water levels are lower and access is improved. Visitors should work with local guides who know the safest routes and best conditions for moving along the water.
During the rainy season from April to November, the surrounding plains transform into extensive wetlands that shelter many animal species. This seasonal shift creates an entirely different landscape that animates the entire ecosystem.
