Caroni

The Caroní rises in the Guiana highlands and flows north to join the Orinoco. Its dark waters cross a landscape of forest, savanna and ancient rock, descending through rapids and waterfalls. The basin encompasses the high tablelands of southeastern Venezuela as well as lower country towards the Orinoco. Its tributaries and forested banks form part of a great river system linking the interior with the Atlantic.

The later city of Ciudad Bolívar lies here.
