Staying near Bercedo
For those who like shorter distances, about 3 km from Bercedo is a Hotel Rural Valtarranz . It is in a town called Noceco. That would give you about a 18 km day from Villasana de Mena to Bercedo, and about 23 from Nava de Ordunte. I have received a note from the owners, who say they are happy to pick peregrinos up in Bercedo or any other reasonable place. But even without that pick-up option, it would leave the day’s total from Villasana at 21.
From Bercedo to Espinosa is flat and sunny, and off road, but that’s about all I remember.
