Tips from the Community
This route is based on the Rompepiernas cycle-tourism event in its short version called “Rompepiernas corta”. The route links several loops starting from Sos del Rey Católico, so it can be done as proposed or only part of the proposed ones. It begins in the municipality of Sos del Rey Católico where we will ascend to the Puerto de Sos along the old road, then we will descend towards Sos and to the bottom of the valley. Then the route goes to Navardún to take the detour to Urriés and the Puerto de Cuatro Caminos. Once we reach the top of the port we will go down towards Undués de Lerda to later make the second climb to the Puerto de Sos. Once we reach the top of the port we will descend, this time, towards Castilis-car, to make the third and last climb to the Puerto de Sos, but this time on the southern slope, passing through Sofuentes and Mamillas. From the top of the port, we will continue towards the old port and road of Sos to end the route in this monumental and medieval town.

We come across a beautiful picture offered by the medieval castle of Ruesta on top of a stony hill, from where there are good views of the Yesa reservoir. It dates from the 11th century and was an important defensive enclave of the kingdom of Aragon during the Reconquest period. Currently, only two towers remain.

Castiliscar is one of those small but charming towns. If we like adventures without crowds, without a doubt we should visit the town of Castiliscar, located within the framework of the Romanesque route of the Cinco Villas through its castle. Walking the streets through the old houses will be like a return to the past.

Despite its curious and striking name, this town is serious when it comes to history and places to visit. Here is the Palace of Sada where King Ferdinand II of Aragon, known as the "Catholic", was born, a place worth visiting to understand the history of Spain. It is also very beautiful to walk its streets and appreciate its stone houses and discover some corner with beautiful panoramic views.

Flanked by the Aragón River and a town on the Camino de Santiago pass for centuries, it is said that this town has a monument on every street and you can see for yourself. Among the sites, the convent of San Francisco de Asís and del Carmen and the palace of Ongay-Vallesantoro stand out among other historical sites from Roman times.

Beautiful picture that the town of Longás gives us, north of Zaragoza and in the region of Cincovillas at the bottom of the Onsella Valley. A spectacular environment for lovers of outdoor sports.
