It consists of two villages, Segl Maria (Romansh, German: Sils Maria; Seglias is part of Segl Maria) and Segl Baselgia (German: Sils Baselgia; Baselgia is Romansh for church); the Val Fex (German: Fextal); and three Maiensässe (Alpine pastures traditionally used for spring grazing): Grevasalvas, Blaunca and Buaira, above Plaun da Lej on the left side of the valley.

Val Fex (Romansh; German: Fextal) is a southern side valley from the Upper Engadine in Switzerland, located at an altitude of around 1,800 to 2,000 metres (5,900–6,600 feet) above sea level.

At the very end one finds the Alp Muot Selvas (2,070 m (6,790 ft)) at the former (about 150 years ago) foot of the glaciers. The river Fedacla runs through the valley, starting at the feet of the three glaciers roughly from south to the north and enters the Lej da Silvaplauna in the Upper Engadine. The valley is dominated by several high Alpine mountains, Piz Corvatsch (3,451 m (11,322 ft)) to the east side of the valley, Il Chapütschin (3,386 m (11,109 ft)) in the far back of the valley, La Muongia (3,415 m (11,204 ft)) and Piz Tremoggia (3,441 m (11,289 ft)) above the glacier Vadret del Tremoggia, Piz Fora (3,363 m (11,033 ft)) above the glacier Vadret da Fex, and Piz Güz (3,166 m (10,387 ft)) and Piz Led (3,088 m (10,131 ft)) above the third glacier Vadret dal Güz.
