We (my wife and I) are planning 10 days in Bavaria the first week of October. Thanks to those who helped us determine bases for our upcoming holiday. We've settled on 5 days in Berchtesgaden (actually, Ramsau) followed by 4 days in Mittenwald. We intended to use public transport entirely but have been advised that in order to see some of the sights on our itinerary (day trip to Hallstatt) we probably need to rent a car for at least some of our time there.
Since we're having to rent a car to visit Hallstatt, we're considering that it might be smart to keep the car for 3 or 4 days in order to transfer bases and to see some of the sights we might want to see in the Mittenwald area. Those sights include Linderhof, Ettal monastary, Wieskirche, Neuchwanstein (not to tour, just to visit the grounds and view from Marienbrucke - I know, I know), and the castles (Ehrenberg) near Reutte.
Now to our questions and need for your help/advice. The tentative plan is to visit Salzburg by public transport on our next to last day in Berchtesgaden (Friday, 5.10), pick up our rental late that afternoon in Freilassing on our way back, then drive to Hallstatt and back on our last day in Ramsau (that would be Saturday). Then on Sunday, we would drive from Ramsau to Mittenwald.
So here's where we have questions. First, what would be the best, most scenic route to drive. Also, keeping in mind that we will have the car all day Sunday and Monday (and if need be Tuesday also), what would be the best plan to allow us to visit those sights outlined earlier on the drive over and the next day or so? We're having trouble sorting out the best order to try to fit these sights in. Any advice or suggestions (including the feasibility of this plan) would be much appreciated. Thanks so much.
