Bourg St Pierre to Grand Saint Bernardo – 12km: A highlight day! For me very emotional as I reached this pass steeped in history. The walk is, as expected, a climb all day. It is not technically difficult, just take your time and soak up the views of the Alps and the change in vegetation as you climb above the tree line. The only thing I would change would be to spend an extra night here to have more time to enjoy this iconic place.
