The municipality is located near the Swiss–Italian border south of the Mera River in the Val Bregaglia (known as Bergell in German).
One theory is that a baker, who had lived in France, brought nut trees back with him which he was able to plant in Val Bregaglia.
He used to joke that his main contribution to physics occurred in the summer of 1930, when he was climbing in the Bergel region near Engadin with another student, Felix Bloch, in the Swiss Alps.
Soglio lies on a ledge on the mountainside on the northern side of the Val Bregaglia (Bergell in German) above the river Maira (Mera in Italian), with views across the valley to the Bondasca glacier and the peaks of the Sciora group, Piz Cengalo and Piz Badile in the Bregaglia Range.
The municipality is divided into two distinct territories, the smaller in the Val Bregaglia and the larger which extends from the two sides of the Maloja Pass and Engadin.
