The Saison[1] (French pronunciation: [sɛzɔ̃] ) or Uhaitz Handia[2] is a left tributary of the Gave d'Oloron river in the French Basque Country, (Pyrénées-Atlantiques), Southwest of France. Its general south to north direction provides the axis for the former French province of Soule. It is also known as the Gave de Mauléon. It is 72.2 km (44.9 mi) long, including its upper courses Zurkaitzegiko erreka and Gave de Larrau.[3]
