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.

Uncastillo, located in the region of Cinco Villas in Aragon, is by the extent of its historical and architectural heritage a real treasure in itself. Around Uncastillo Castle, there are no less than six churches. They all date from a different era. The Church of San Martin in Tours, with its magnificent Romanesque porch and its expressive characters, clearly dates from the Romanesque period. The Church of San Andrés, with its colonnades and its coat of arms, is more from the Renaissance period. Don't miss, finally, the museum of the Tower. If you are tired of religious monuments, do not hesitate to get lost in the many streets of the village.

We are in the Pígalo pools, ideal for warm summer days where we can take a dip. If we go upstream, we will find more less crowded pools, since this one is quite popular and soon fills up with people. If we want to leave the car in the car park, we must book on the Luesia town hall website as they control access. There are picnic areas to eat and a bar at the campsite.
