What a picturesque, lonely side valley! The rushing Rosegbach accompanies you all the time. And a little further back in the valley you can see the wonderful glacier panorama of the Bernina massif. A real feast for the eyes!
One of the famous Upper Engadine lakes (along with Lake Sils, Lake Silvaplana, Lake Champfer). Can be hiked all around on a partly paved path, the south side is closed to bikes.
