The PR-HU 113 , known as the Baélls to Estopiñán Trail , is a short-distance route that connects the regions of La Litera and Ribagorza , combining tradition, heritage, and landscape. It is an ideal itinerary for those who wish to discover the natural and cultural transition between these two territories, passing through emblematic sites such as the hermitage of San Quílez , the highest point in La Litera, and the historic Font Redona spring , which has supplied water to local orchards for centuries.

The route begins in the village of Baélls , where we take the GR 23 towards Peralta de la Sal. We soon come to the hermitage of Santo Toribio , a small church of historical interest, and shortly afterwards reach a fork in the path. While the GR veers to the left, the PR-HU 113 continues to the right, following farm tracks until reaching Zurita.

Upon entering Zurita, we take the path to the right and begin a gradual ascent towards the hermitage and viewpoint of San Quílez , from where there is an extraordinary panoramic view of the Pyrenees and the Ribagorza region. From this point, the trail crosses the regional boundary and enters Ribagorza, descending to the hamlet of Mas Blanc.

Following the PR trail markers, we arrive at the popular Font Redona , a circular fountain that stands as a testament to the traditional use of water for agriculture. From here, the route continues east, crossing several crossroads, until reaching the town of Estopiñán , where the trail ends.
