The enviable natural environment of the Valley of Roncal has provided locals with hunting and fishing grounds for as long as anyone can remember (as a means of subsistence in days of old and as a sport in the present day).

These practices are now regulated through reserves and by different hunting and fishing associations in order to manage the different species that live in the valley properly.

The chief game species in the valley are wild boar, roe deer, red deer and woodcock; and the main fish are trout, South-west European nase and barbel.
