During the mining era, this pass served as a discreet link between mines on either side, and minimal traces of old cart and mule traffic remain, though they don't coincide with the current road. From above, the wind is almost constant, and the view towards the Saliencia lakes has that air of a "natural viewpoint" before the term even existed. It's perfect to mark on Komoot as a key point on your route due to its spaciousness, its somewhat hidden history, and its character as a natural border.

A glacial lake nestled between limestone walls, with a little-known detail: beneath the surrounding meadow, remnants of the old road used to transport materials for the region's former water network are still visible—a nearly erased trace that lends the place a dual character, both natural and industrious. The lake changes dramatically with the light: on cloudy days it appears opaque and heavy, but in sunlight it displays an intense green that reveals its depth and rocky bottom. It's a good spot to pause and appreciate the contrast between the wild landscape and the barely visible but still present vestiges of human activity.
