Course
From the point where the Uribante joins the Sarare, the Apure flows eastward across the Venezuelan llanos, into the Orinoco. The Apure flows primarily through Apure State including San Fernando before joining the Orinoco River via six braided river branches west of Cabruta, Guárico State, across from Caicara, Bolívar State, at about 7°40′N 66°25′W / 7.667°N 66.417°W / 7.667; -66.417. The Apure is 645 miles (1,038 km) long from the Uribante's starting point to the Orinoco. It is navigable for about 500 miles (800 km) above the Orinoco, where it has a sluggish course across the llanos, despite rapids at about the 110-mile (180 km) mark. From the north, its principal tributaries are the Caparo, Portuguesa and Guarico. The Caucagua is its only major tributary from the south. Because of the flatness of the land its meanders and bayous to the south are mingled with those of the Arauca River creating an extensive area which is flooded annually. However, both rivers keep independent channels during dry season.
