Paillon

The Paillon (Nissard Occitan: Palhon) is a coastal river of the Alpes-Maritimes that flows into the Mediterranean Sea in Nice, near the old district. It is 35.8 km long. Its drainage basin is 258 km2. Its source is north of Lucéram. It flows generally south, through L'Escarène, Peillon, Drap (where it meets its main tributary Paillon de Contes), La Trinité, and finally Nice.

Being a typical Mediterranean river with low water level throughout the year but with the autumn and winter rains can turn violent with damaging floods.

The region of the Paillon and the Paillon de Contes is called the pays des Paillons. The river course was covered and converted into a subterranean stream for its last few kilometers in the city of Nice starting at Rue Georges Chapel to its mouth at Plage de Carras. Two major buildings built over the stream are the LGT Lyceé Guillaume Apollinaire Nice High School the Palais des Congrès Acropolis.
