Hi, I'm trying to workout "transportation options" along the Caminho using perhaps Porto, Ponte de Lima,Valenca/Tui as "bases" and bus/train to and fro from end/start of each days walk.[with day packs hope to follow as close as possible the 5 day option for walking distances set out by the online Camino Portugues. Would appreciate all/any advice/suggestions THANKS :? PS..This is to avoid the possible crowds in the albergues,and at these larger? towns a bigger choice of accommodation.
