Introduction to the Gemmi Pass: The Gemmi Pass was originally the only way for the outside world to enter Leukerbad, and it has the longest and most dangerous rock climbing route in Switzerland. It is a place not to be missed by people who love outdoor sports. Starting from Leukerbad, passing through the Gemi Pass, crossing Shimamoto Lake, and finally arriving at Kandersteg in the Bernese Oberland, it is also the most classic hiking route.
