Bar and Restaurant 1km from the dam on the way back up.
The hydroelectric dam here was built in the early 1950. The abandoned concrete structures on the north side of the dam are leftovers from its construction, which required that most of the materials (primarily the concrete) be produced on site.
What goes down must go up, in this case it is about 300m back up to Grandas de Salime. It is mostly, but not entirely, along the road. Along the way is a scenic overlook (about 2km from the dam). Shortly after the most severe turn in the road (a 180 degree bend) the camino turns left to follow a trail uphill.
