Hello Piero. My wife and I are planning to walk from Gran St Bernard's Pass to Rome in Aug-Oct next year. We want to spend a few days in Bologna before catching the train to Aosta and then travelling by bus to GSBP. I understand that Swiss Post operate two bus runs per day from Aosta to GSBP but can't get any sense of the departure times (not even on their website). Do you have any sense of the departure times?
Walked from Porto to Santiago in 2015 with a friend, and then from Hendaye, on the French side of the border, across the Northern route, cutting south east on the Primitivo, unaccompanied but never alone, in 2017. I'm beginning my prep (long range) for a pilgrimage on the Francigena, from Lucca to Rome, in 2020. These pilgrimages work their way into the blood and bones, I think.
