Thanks to all for the great advice. We’re walking the VF from Viverone to Fiorenzuola d’Arda this year (having walked Fiorenzuola d’Arda to Rome in past years) and wanted to cut the last stage from Piacenza to Fiorenzuola d’Arda in two. (We’re in our 70’s and the distance we like to walk in a day has gone down.) Couldn’t find anything in Pontenure so we were planning to walk there, train back to Piacenza and then back to Pontenure in the morning.
At Andycohn’s suggestion I researched Volcanasso. The religious center there had no space, but I was able to reserve at Agriturismo Mancassola, so we’re all set. Thanks to everyone; as always, this forum is great!
