Orinoco

Stretching over 2,400 kilometers, the Orinoco River is one of South America’s largest waterways. Discovered by Christopher Columbus during his third voyage to the Americas in 1498, the Orinoco River basin covers 880,000 square kilometers across Venezuela and Colombia. The headwaters of the Orinoco were not mapped until the 1950s, however. The Orinoco delta is home to the Warao people, whose name translates as “people of the water” - an apt description as the river basin offers substantial fish and wildlife resources. Manatee, river otter, parrots, catfish, and many other types of fauna are found in this land, where the ebb and flow of river and earth have continued unabated across generations. Humid, tropical, lush with life in abundance, the Orinoco region is to this day an example of a world primeval.
