This section of the GR 262 between Montalbán and the district of Peñarroyas stands out for the chromatic variety of its landscape, especially in autumn. In the same town of Montalbán, next to the river, on its left bank, we can start the path in the Paseo de la Garona, which outlines the base of the hill where the castle of Montalbán known as “Las Peñicas” was built and where some constructive remains associated with “dovecote towers” can be seen on the top.
Leaving Montalbán behind, the trail runs to Peñarroyas along the right bank. At first, the trail flattens out along the riverbank and advances down the valley through some poplar trees that flank a path that leads to the Mill, where we take a path that later links up with the El Baño recreational area, ideal for a rest stop next to a fountain and picnic tables. (In this area is located in the link with the PR-TE 99 of the Ancho river and the Muela that we can climb back to Montalbán and link with the massif of the Muela).
The trail follows practically next to the riverbed and soon begins a stretch that ascends halfway up the slope to skirt the vineyard headland. It will descend again to the river that we will reach by linking with a forest trail to go up again, with a little more slope, the cabezo de la Plana, which will offer beautiful panoramic views of the Martín valley to the Peñarroyas neighborhood, characterized by the reddish gap of the reddish rocks that give it its name and that cut transversely the Martín. The path ends near the mill to cross the riverbed and reach the town. A picnic area with barbecue included at the entrance of Peñarroyas could be the end of this stage.
