We will be visiting Berlin, Prague, Cesky Krumlov, Salzburg, Oberammergau (Passion Play), and Munich before catching a Danube cruise in Regensburg next September. Train and/or bus service between these cities seems to be the best approach to see some of the countryside in the process.
Our research reveals a number of convenient bus connections using Leo Express, Flixbus, EU Shuttlebus or CKShuttle/Bean Shuttle assuming we do the Berlin-Prague leg by train.
Looking for insights into these various ground transportation options as an active retired couple.
