The Upper Engadine (, ) begins at the Maloja mountain pass () in the southwest with a subsequent chain of lakes running southwest-northeast: Lej da Segl (, ), Lej da Silvaplauna (, ), both famous for windsurfing, and Lej da San Murezzan (; , ). To the southwestern side, the Maloja Pass drops precipitously down to the Italian spoken Val Bregaglia () and then over the Swiss-Italian border further down to Chiavenna (), and thence southwards to Como. Near the Lunghin Pass (), northwest from and above Maloja, lies the most notable triple watershed in Western Europe, from where the water flows via the Inn and then via the Danube to the Black Sea, via the Maira and then via the Po to the Mediterranean Sea, and via the Gelgia and then via the Rhine to the North Sea.
