Introduction: The Lauterbrunnen to Sion Drive

Spanning approximately 110 kilometers, the journey takes about 2.5 hours without stops, but most travelers spend a full day exploring. A little-known fact: the Grimsel Pass (Hauptstrasse 6) reaches 2,165 meters and features the famous Lake Räterichsbodensee, whose turquoise color is due to glacial flour.
