This stage is one of the most spectacular in terms of scenery. The Bonaigua Pass connects Pallars with Navarre through high mountain landscapes, glacial valleys, and historic passes. You will go through Esterri d'Àneu and descend into the Roncal Valley, where Burgui and Isaba have kept a strong cultural identity linked to wooden rafts (almadías), transhumance, and Pyrenean architecture. The local cuisine reflects this pastoral heritage.
