From the summit of Peña Main there are spectacular views of the whole of the central massif. This is a lovely route taking you over the Peña Main range and through the farming pastures above Tielve. Care is needed as the paths are not well defined in the higher section of this walk. From the finish to the start of the walk it is 6 km along the road.
