WaterhazardJack I will be relying upon public transports, trains or coaches. There does not seem to be a direct train, so would it be possible to do in it in one day via Linz or Salzberg?
Can be done in a variety of ways...the most straightforward way to get there is by the shuttlebus from www.shuttlebus.cz which takes 4 hours...however, this is expensive at 1700CK or €68...
Some alternatives are to take the train to Linz, then the train to Ceske Budejovice and train or bus to CK...
Or the Student Agency Bus to Plzen, train to Ceske Budejovice and train or bus to CK...
There is another method that is cheap and very scenic but long and difficult for an outsider...involves taking the train from Munich to Passau, bus from there to Haidmuehle, walk across the border (2kms) to Nove Udoli and then the train from there to CK...this works out very cheap with a Bayern Ticket covering the train to Passau and bus to Haidmuehle but depends on a lot of connections and some infrequent services...
