About this water

A classic Catalan Pyrenean trout river flowing south from the Aigüestortes-Pica d'Estats massif through the Vall de Cardós to join the Noguera Pallaresa near Llavorsí. Cold, clear freestone water of limestone-mountain character, holding wild native browns. The valley supports several controlled trout zones (ZPC) with technical pocket water and small-fly fishing. Snowmelt-dominated through May; summer can be excellent in the cool upper reaches. A good intermediate-to-advanced wild-trout destination.
