This granite mountain range, culminating at Pic Long (3,192m/10,472ft), reveals stunning landscapes, exceptional wildlife and plants and countless lakes that shimmer in the sunlight. Before embarking on the paths of this magical site, take the time to visit the wooded Rioumajou valley and the Moudang valley, at the end of which is Piau-Engaly, one of the best skiing areas in the Pyrenees, or climb up to Aubert pass.
