4.80km → El Castillo (Soto del Barco) → 0.90km → Soto del Barco
To Santiago: 

The town earns its name from the nearby Castillo de San Martín, which was an improvement on the castle that the Romans built in the same location.

The Road: 

Descending from the castle overlook the camino arrives at a roundabout littered with old arrows and new arrows. At this roundabout, which is now cut off by guard rails, the camino does NOT turn right. Instead it follows the road a bit longer to the next roundabout. At this roundabout it does NOT turn down the N-632 to Muros de Nalon, but rather takes the second exit to pass the hotel in Soto del Barco.
