“Water’s struggle on the Swabian Alb” is a fascinating one: here you find the European watershed, the line between the water that flows into the Rhine and the water that flows inti the Danube. The courses of its streams and rivers are breathtakingly romantic, their banks dotted with mediaeval castles. The most dramatic scenery is to be found in the upper Danube valley. The springs gurgling out of Jurassic stone, the meandering rivers and almost mystical spring pool (Blautopf, Brenztopf) are unforgettable natural phenomena that make this area so attractive.
