Livigno lies at an altitude of 1816 m s.l.m. in the Livigno Alps, is a duty free zone and a popular winter sports resort. It is located on the river Spöl (today also in Italian so, formerly Aqua Granda), which flows through the Livigno Valley from south to north, with a dam on the Italian-Swiss border to Lago di Livigno is dammed and then at Zernez in the Engadin in the Inn and thus flows into the Danube. So the valley lies north of the watershed of the Alps.
Trepalle, a district of Livigno, is by its own account the highest permanently inhabited place in Europe at an altitude of 1907 to 2250 meters, on the Passo d'Eira. However, most sources assume that the Swiss hamlet Juf in the municipality Avers GR deserves this title. The theory dispute is therefore based on the fact that the highest houses of Trepalle are actually higher than those of Juf, but the deepest houses in Trepalle are more than 200 meters lower than those of Juf. In addition, Juf - unlike Trepalle - forms a closed settlement. Generally, however, the core of a settlement (office building, church, ...) chosen as a reference point, otherwise many communities in the Alps due to more or less high above the center enthroned, partly now year-round inhabited alpine settlements, Maiensässe etc. this title could take.
