Located in the Upper Engadin valley, Sils nestles between Lake Sils and Lake Silvaplana at the foot of Piz Corvatsch and Piz da la Margna and below the Fex valley. Sils/Segl was originally divided into the two hamlets of Sils Baselgia and Sils Maria, but the two are now almost a continuum. The town is in a flat plain between the two lakes, with steep slopes on either side. The plain is cultivated in grass, the steep slopes are heavily forested.

Sils hosted Friedrich Nietzsche in the summers between 1881 and 1888, and the house he lived in is now a small museum. Anne Frank was in Sils for several vacations, and Hermann Hesse also visited Sils.

The official languages are German and Romansh, reflected in the double name. The Fex valley is officially car-free except for residents of the valley. The Furtschellas cable car begins near the village and leads to many ski runs and, in summer, to trails above the tree line.
