Río Gállego — Río Gállego, Huesca, España, 2023-01-05, DD 12-16 PAN

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 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.
