(S) Our route leaves Berducedo from the church of Saint Mary heading west to climb a cemented road that becomes a dirt track as it levels off. Once past the last buildings, bear left at a fork and then left at a T-junction. Bear right at the next fork and follow this path along the hillside, climbing gently to meet another track. Bear left to head in a southwesterly direction, across streams and finally ending up at the church of Saint Mary Magdalen, in the hamlet of A Mesa.
(1) The small shop in A Mesa is only open in July, August and September so make sure you have enough to keep you going until you reach Grandas. Leave the hamlet heading west then north to climb steadily uphill to As Rozadas where the windmills are clearly visible. The track bends left quite sharply to go round the other side of the hill and then bends right to go downhill to the chapel of Saint Theresa and Santiago(James) in Buspol. Here the descent starts, at the end of a farm track, heading west. Bear left onto a path that goes downhill in a zig-zag pattern. At first, the route follows a cattle track of dirt and stone. Soon you should be able to see the Salime reservoir in the valley and the town of Grandas de Salime, our destination, on the other side. The descent, which doesn't have an excessive slope, is divided into three parts. The first part, along a wide dirt and stone track in long zig-zags, and in which we lose altitude little by little. The second part is along a dirt forest track, which is pretty flat and even has a short climb, and in which it seems that we are going too far from the reservoir, which is down to our left. The third part begins when we leave this track to take a nice path to the left, which zigzags through a forest until it comes out onto the road that, on the left, leads us to the Mirador Boca de la Ballena.
(2) This viewpoint offers a spectacular view of the reservoir and the Salime dam. With access from the road through a tunnel dug into the rock. Once you've admired the engineering, it's time to cross the dam. The AS-14 road goes right across then heads over to El Salto, passing the Hotel Las Grandas. Our route continues along the AS-14 road with very little relief apart from the views over the reservoir and the shade from the pine trees. After a particularly pronounced bend to the right, there is a recreational area with some tables and benches, even a bus-stop! Ignore the road that heads towards Pénjamo and a viewpoint, rather follow the road west for another half a kilometre. Just after the 2km sign, take a track off to the left that takes us through woodland parallel to the road. After about one and a half kilometres there is another recreational area with tables and benches. Shortly afterwards, the path gently descends to join the road just before the righthand turn off to enter the village of Grandas de Salime.(E)
