6.30km → Piedratecha → 3.40km → Villaluz
To Santiago: 

After descending from the alto you emerge onto the main road (AS-350) in Piedratecha which no longer has a bar.  Turn right and follow the road.  About 600m the camino bears to the left along a trail. 

Halfway down the hill to Vilaluz there is an option detour to the ruins of the Monasterio de Obona.
