Orneau
The 883rd longest river in the world
The Orneau (French pronunciation: [ɔʁno], Walloon: Ôrnô) is a river in Belgium. It is a tributary of the Sambre and therefore sub-tributary of the Meuse. The Orneau flows from north to south, through the province of Namur, and after a journey of about 25 kilometres (16 mi), it flows into the Sambre at Jemeppe-sur-Sambre. The river is known for its valley, panoramic views and nearby charming villages. Several walkable trails exist near the river.
