If you wish to stay in the albergue here, be advised that it is not in the village proper but rather set off from the main road a bit to the north.
Do not let the grandiose name of the village fool you, neither the town nor the river is remarkable.
Best to avoid Villamayor del Rio. The smell of cow manure being transported in trucks was overwhelming all night and we stayed at a private albergue —not too friendly. But the highlight was dinner at Cafe Leon whose proprietor is a warm gentleman who is extremely knowledgeable about local history. In fact his restaurant contains a small museum of medieval artifacts. He went out of his way to give us a lovely non-pilgrim meal and gave us the grand tour—-most entertaining and a highly recommended stop. Mind you this was 2012, so things may have changed.
