I shall be staying in Munich. Is it possible to go by train to Garmisch-Partenkirchen to see the Partnachklamm only; not the hiking trails and from there proceed to see the Neushchwanstein castle (not the interior; it is incomplete and I do not want to pay the entry fee to see an incomplete castle).and do this all in one day? If possible, also see the Alpensee in Fussen. If so, how does one proceed by train/bus from Garmisch-Partenkirchen to Neushchwanstein castle on a Bayern ticket? How many hours do you think this will take from and back to Munich?
