Geographically, Pfullendorf lies between
Lake Constance in the south and the Danube Valley
in the north. In the West you'll the almost volcanic landscape of the Hegau and in the east you quickly reach the Upper Swabia area and the Allgäu, where you can ski in winter.
The "four-rural region of Lake Constance", which stretches from the German coast, Switzerland and Austria to the Principality of Liechtenstein, literally opens borders and is always worth a stay.
