Alpine environment of rare beauty. I recommend mountain equipment and gear. Violent hailstorm just as we were on the pass.

From Cignana's window the gaze embraces a vast panorama: from the artificial basin below to the peaks that surround it, up to the Monte Rosa glacier. From this point three paths branch off towards different destinations. The path that leads to Mount Pancherot, directly to the south, is the shortest but also the most technical. Running up to Lake Cignana is pleasant and easy. Alternatively, you can take routes that lead to more distant destinations.
