My apologies if this is not the proper forum to post in as I realize from of these areas are not in Bavaria.
I will be flying to Frankfurt and heading South/West through Germany and back up to Prague. My father who was born in the area has given me some points of interest but I'm looking to others here for more. We will have a car and will be in the area for 2.5 weeks. We are open to exploring other countries as well such as Liechtenstein and Austria, basically we're completely open at this point.
Please let me know. Thanks in advance!
