Spectacular easy/medium level guided route in which we will visit the ruins of the old Tuca ski resort, continuing the circular route towards the bed of the Nere River, descending to Vielha along its side. It is a 30 km route. The maximum difficulty of which lies in a 300-meter section of a path that runs through the spectacular Sarraera forest, to later connect with the track that runs parallel to the Nere river, now without any technical difficulty. It is recommended to bring windbreakers, something to snack on, and water in your backpack. We meet at the agreed time in the reservation at Bicius Val d’Aran (Vielha).
