Aro

The Aro River drains part of the Guiana Shield south of the Orinoco. It is formed by the Sucre, Azul and Alachuela rivers and flows north through the country of the Venezuelan interior. Its basin lies among the great tributary systems of the Guiana highlands, where rivers cross ancient rock and descend towards the Orinoco. Forest and savanna border the waterways that connect this inland country with the main river.
