Aix-en-Provence to Davos: Ultimate Road Trip Guide

The Aix-en-Provence to Davos drive is a trans-European journey of about 870 kilometers (540 miles), crossing from the sun-drenched south of France into the Swiss Alps. The precise fact: the route passes through three distinct geographical zones—the Provencal vineyards, the Rhône valley with its mistral winds, and the Alpine massif culminating at Davos at 1,560 meters (5,118 feet) above sea level. The driving time without stops is approximately 9 hours, but you'll want at least two days to savor the transitions.
