The Gállego rises near the French border and takes its time getting to Aragón — a proper Pyrenean river that passes through high country before it moderates into the managed beats below Sabiñánigo.

About this water

The Gállego rises near the French border and takes its time getting to Aragón — a proper Pyrenean river that passes through high country before it moderates into the managed beats below Sabiñánigo. The catch-and-release sections hold serious wild brown trout in water that runs cold from the snowfields well into July. The fish here come from altitude, clarity, and a diet of real insects, and they behave accordingly. The Alto Gállego is the part worth knowing: above the reservoirs, where the Pyrenean character is intact and the trout have not yet learned to be accommodating.
