The Ulm–Sigmaringen railway is a 92.670-kilometre-long railway in Baden-Württemberg in south-western Germany, which is largely single-tracked and for the most part not electrified. It runs from Ulm via Blaubeuren and Riedlingen to Sigmaringen mostly in the valley of the Danube. The line is part of the once important long-distance connection from Munich to Freiburg im Breisgau.

EuroVelo 6 (EV6), named the "Rivers Route", is a EuroVelo long-distance cycling route that runs along 3,653 km (2,270 mi) some of Europe's major rivers, including much of the Loire, some of the Saône, a short section of the upper Rhine and almost the entire length of Europe’s second longest river, the Danube — from the Atlantic coast of France to the city of Constanța on the Black Sea.
