It should be the most beautiful lake in Switzerland. Bachalpsee Lake at 2265 meters above sea level is an alpine lake in the Jungfrau Mountains. The most beautiful moment is the reflection of the schreckhorn's sharp and towering mountaintops on the lake as calm as a mirror. The trail, from first to bachalpsee, was named one of the world's 15 most classic trails by National Geographic in 2012 and described as beautifully absurd.
