Caratteristiche

Località

On the Burgui Roncal road (NA 137), past km 20 and "Puente Nuevo", two ravines descend along the right bank of the Esca river: the larger one is the Bochuela and the other, smaller one, is the Erlarena. A path climbs to Mendibelza crossing a scree slope secured with a cable; to the left a limestone gap can be seen, 50 m further down, among shrubs, the entrance of the cavity opens.
