The ruins found on the track that connects Luesia with the Pígalo pools are known as the castle of Sibirana. The ruins of the hermitage of Santa Quiteria also remain from this deserted area. This nucleus is part of a defensive line ordered to be built in the 10th century by King Sancho Garcés I of Pamplona.

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.
