We are going to Germany in early September with reservations in Oberammergau for 2 nights & tickets for the Passion Play. We have already hit many of Rick Steves' highlights: Nurnberg, Bacharach, Rothenburg ob der Tauber, Munich, Garmish, Berchtesgade, a Rhine river cruise stopping at Breisach, Speyer, Heidelberg, Rudesheim & Cologne.
For this trip, I'm considering a circle that can begin/end in Zurich, Munich or Frankfurt. Arriving in Frankfurt, the trip would include Baden-Baden, the Black Forest High Road, Short & Scenic Black Forest Highlands Drive and stay in Freiburg for the drives. Maybe a night in Staufen then onto Lake Constance staying in Meersburg or Konstanz with a day trip to Mainau, Taking the Alpine Road to Oberammergau, side trip to Linderhoff Castle, a few nights in Garmish then the Romantic Road to Rothenburg, Wurzburg (what do you think of this town) then fly out of Frankfurt.
We prefer the smaller, quaint, quiet towns and don't need 5 star restaurants or night life. There are no confinements on our time away, as we are both retired. Our thoughts are 10-14 days for the trip. Thank you for your insights!
