At its mouth, the Orinoco forms a wide delta that branches off into hundreds of rivers and waterways that flow through 41,000 km² of [[swamp]]y [[forest]]s. In the rainy season the Orinoco can swell to a breadth of 22 kilometres and a depth of 100 meters.

Most of the important Venezuelan rivers are tributaries of the Orinoco, the largest being the Caroní, which joins it at Puerto Ordaz, close to the Llovizna Falls. A peculiarity of the Orinoco river system is the Casiquiare canal, which starts as an arm of the Orinoco, and finds its way to the Rio Negro, a tributary of the [[Amazon]], thus forming a 'natural canal' between Orinoco and Amazon.
