The Upper Engadine is characterized by a large flat area, where there are four lakes: the lakes of Sils, Silvaplana, Champfer and Sankt Moritz. Around this plain there are thick forests of stone pine and larch, while on the surrounding mountains the presence of glaciers is relevant. This part of the Engadine is located between 1,600 and 1,800 meters above sea level.
The Upper Engadine is connected to the Bregaglia Valley via the Maloja Pass and to the Val Poschiavo from the Bernina Pass. The municipalities of the Upper Engadine are, starting from the south: Sils im Engadin / Segl, Silvaplana, St. Moritz, Celerina / Schlarigna, Pontresina, Samedan, Bever, La Punt-Chamues-ch, Madulain, Zuoz and S-chanf.
The Lower Engadine is morphologically very different from the Upper one: it has a much more steep slope (between 1,610 and 1,019 meters), is narrower and the Inn has carved over the centuries deep gorges between the rocks. This section of the valley ends at the border with Austria. In the Lower Engadine there are the municipalities of Scuol, Valsot and Zernez.
