Just purchased tickets for a 9 day trip to Germany for early October 2013. We will arrive in Frankfurt and leave from Prague. We will have a car as we are meeting old friends who now live in Germany. I am most interested in Southern Germany/Austria as a route to Prague but know next to nothing! Any advice or ideas for an itinerary or route would be much appreciated. We are in our 50's, fit, interested in hiking/food/beer/natural beauty/history/small, beautiful towns and nice people. Many thanks!
