The social center of town is the Bar Borox / albergue.
Beyond Barcial de Barco a bit of care is needed to keep to the camino. If you have any doubts, speak with the owners of the bar Borox (adjacent to the albergue), they sometimes provide a map of the way.
The confusion has to do with the recent development of a disused railway line into a pedestrian path known as the Via Verde. This is the recommended way as it delivers you directly to the albergue in Benavente (which itself is in a repurposed rail yard building).
After leaving Barcial de Barco the camino returns to the N-630 and crosses it; at this point you can see (ahead and on the left) the elevated Via Verde. The camino will eventually pass beneath it, and it is here that you can take the stairs up to the walkable level. From there it is a simple matter of following it all the way to the railway yard in Benavente.
