Hi Maltasr. As an Aussie I am just relating how we have got around this area using public transport. We have a good friend who lives in the great village of Pigra. We have flown into Milan & then caught rail to either Como Lago or Como San Giovanni. Depending on the timing we have either caught the C10 bus or the ferry to Argegno. We have moved around using ferry or bus & enjoyed ourselves around Lake Como. Not a big % of visitors get to Pigra but we love mixing with the locals & getting to the bars & especially the pizza at the pub.
Last time there we caught a shuttle bus from Chiasso to Linate prior to our flight out.
