46. Lake Constance Bike Marathon

7th September 2019 marks the day again: the 46th bike marathon that takes you around the entire Lake of Constance. On one day, on three routes. Further information on the event and on registration can be found here.

Tour around the lower lake

A day tour around the lower lake. The tour starts in the Hotel K99 in Radolfzell, taking the cycle path to Konstanz via Markelfingen and Allensbach.

From Konstanz, you continue your route along the lake towards Stein am Rhein (Switzerland), passing through Gottlieben, Ermatingen, Steckborn and Mammern. We recommend taking a break in Stein am Rhein to enjoy its beautiful city center and its medieval old town.

Cycling back to Germany, you ride along the lake via the peninsula Höri, Wangen, Gaienhofen and Moos. The trip can be shortened at various points by taking a boat, e.g. from Steckborn to Gaienhofen.

The Lake Constance Cycle Path

The Lake Constance Cycle Path is one of Europe's most favourite bike paths. The tour around the whole lake will take you through three countries: Germany, Austria and Switzerland. Being approximately 260km long, the tour can be conveniently split up into day trips, almost always letting you cycle along the lake.
