Here the Camino Aragones begins at the top of the pass on the Spanish side of the pass. A great view down into the valley.

The Aragonese Way of St. James begins at the top of the Somport pass. From above you have a wonderful view down into the valley towards Jaca. A very good start to the Camino Aragones, which still remains really original.
