Boi Taull ski resort and Cavaller Dam

Long but fun route that aims to visit one of the prettiest corners of the eastern Pyrenees.
Leaving from Jaca, we will go to Biescas to ascend the N-260 (I have talked here on another occasion about this magnificent route) to the town of Foradada del Toscar, Campo, Castejón de Sos, and Montanuy, the last town in Aragon before crossing into Catalonia, here to Vilaller (N-230 road from Lerida to Vielha) towards Pont de Suert before arriving we will turn left (L-500) and ascend following indications, first to the ski resort of Boi Taull (L-501), and we will descend again to the same intersection where we took the ascent to the station, to the right the road will lead us to the Cavallers dam (LV-5000).
On the return trip, we will go back to the town of Bonansa (A-1605) remaining alert for the turn we will make to the right towards Espes and Espes alto to fall again onto the N-260 back to Castejón de Sos, from here there is no mystery as we will retrace the N-260 to take a detour through Fiscal and its tunnels towards Sabiñanigo and Jaca.
