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?
