About this water

A classic Catalan-Aragonese Pyrenean river flowing southwest from high limestone plateaux. Limestone gorges alternate with alpine valleys throughout; clear, alkaline freestone holds brown trout with good size distribution in upper reaches. Technical runs, pools, and pocket water reward careful presentation. Karst geology means rapid spate response sustained by groundwater storage. Access from La Pobla de Segur (middle) or Espot (upper). Long fly-fishing tradition makes this a mature, rewarding destination.
