St. Moritz to Konstanz Road Trip Guide

The drive from St. Moritz to Konstanz covers roughly 220 kilometers, but the route is far from ordinary. One of the most striking features is the dramatic descent from the Engadin valley at 1,800 meters to Lake Constance at 395 meters above sea level. Along the way, you'll cross the Julier Pass at 2,284 meters, a pass that has been used since Roman times. The Romans called it 'culus'—meaning 'pass'—and today you'll find the ancient Roman milestone at the pass summit.

The journey begins in the Engadin valley, surrounded by the Bernina Alps. The forests are dense with Swiss stone pine, giving the air a distinctive scent. As you descend, the landscape transitions from alpine tundra to vineyards near the shores of Lake Constance. The change in vegetation is striking—from larch and pine to apple orchards and grapevines.
