What a starting point, what a destination: from picturesque Heidelberg via the exciting Black Forest to the no less beautiful Lake Constance, this cycle route takes you all the way through Baden-Württemberg, 300 kilometres from north to south.
From Rottweil, the cycle route initially follows the Neckar upstream to its source region in Schwenninger Moos. From Villingen-Schwenningen, the route continues along the plateau to Donaueschingen.
