It is a very curious route because it is marked by more than a hundred stone pylons, built in the eighteenth century, which were used for orientation in times of snow and frequent fog at this altitude. The road has been declared an Asset of Cultural Interest (BIC). It is also known as Camino de Jaime I because there is evidence that this king walked it on some occasions marching towards the conquest of Valencia.
From Allepuz, we ascend the rocky outcrop above the hamlet until we reach the San Cristóbal peirón. Next to it begins the succession of stone pylons of more than 2 meters high, which indicate the direction to follow. A short stretch of trail ascends the Loma de la Hiedra. Halfway, the route enters a small pine forest and continues in a northeasterly direction to the paridera del Rallao, where another stretch of path of great beauty begins. The path descends to the water spring that supplies the Tosco sawmill, crosses the road and continues on the other side of the Pavías ravine, ending in Villarroya de los Pinares.
