If you ever visit Neuschwanstein Castle, which is along the Austrian border in Bavaria, this is as close as you can get in your car. The rest of the way is either on foot or paying for a horse drawn wagon to pull you up the hill.
This is my last weekend in Germany for the forseeable future and so I spent making the 3 hour drive (one-way) from Nuremberg down here to the little village near Fussen where the castle is located. The official site (in English) is here: http://www.neuschwanstein.de/english/
