It flows in a south-southeast direction along the western edge of the Amazon basin . At river kilometer 442 the trunk road E40 ( Santiago de Méndez - Puerto Morona) crosses the river. This crosses the border to Peru at river kilometer 435 and then flows through the province of Datem del Marañón . It shows a strongly meandering behavior with numerous river bends and oxbow lakes . The Río Morona finally flows into the Río Marañón, 116 km below the breakthrough valley Pongo de Manseriche and 558 km above its junction with the Río Ucayali to the Amazon .
