About this water

A major river draining the central Aragonese Pyrenees from granite headwaters to limestone foothills. The Cinca's best trout water lies in the upper reaches — Pineta valley, Bielsa section, and down through Lafortunada. Mixed geology creates varied habitat and prolific wild-trout populations. Strong gradient requires good wading; technical presentation essential.
