The Adour River rises in the central Pyrenees near Tourmalet Pass, just south of Midi de Bigorre Peak, and flows in a curve, north, then west, to enter the Bay of Biscay just below Bayonne after a course of 208 miles. It passes through Hères and by crossing the village bridge you move from Hautes-Pyrenees to le Gers. Hères is traditionally a farming village and the Adour valley produces maize, vines, soya and sunflowers. Poultry and some cattle are raised as well as the “black pig”.
The village has an old church and a village hall (salle de fête) where events are held throughout the year.
