St. Moritz to Flensburg Road Trip Guide: Epic 1,200 km Drive

The road from St. Moritz in the Swiss Alps to Flensburg on the German-Danish border covers roughly 1,200 kilometers. It traverses four countries: Switzerland, Austria, Germany, and a brief slice of Denmark. A peculiar fact: the route crosses the European watershed twice, first at the Alpine divide and later at the North Sea-Baltic divide near the Elbe. The most efficient path uses the A1 motorway in Switzerland, the A7 in Germany, and the E45 in Denmark, taking about 12-14 hours of pure driving.
