View of the Belagua Valley

Highlight • Viewpoint

At the bottom of the Roncal valley, right where the climb to Puerto de la Piedra de San Martín begins, you will find this beautiful bend in the mountain called Belagua. It is an idyllic place that you can best enjoy if you climb up following the road to Venta de Juan Pito.

View of the Roncal Valley from Cuartel de los Yeguaceros

Highlight • Viewpoint

Going up to the Puerto de la Piedra de San Martín through the Roncal - Belagua valley, after the first 5 km of hard climb with a section of continuous hairpin bends, you reach the abandoned Guardia Civil barracks.
This place is ideal for the views it offers: on the one hand, you can see the Roncal valley from above in a panoramic view (simply spectacular); on the other hand, looking up towards the valley, you can see (if the weather permits) the peaks around the beautiful ski resort of Larra - Belagua, which should not be confused with the Piedra de San Martín ski resort, located in France.
