Monte Rosa cover areas on both sides of the border between the Swiss canton of Valais and the Italian regions of Piedmont and Aosta Valley. The main summit of Monte Rosa is the Dufourspitze. On the Swiss side the town centre of Zermatt is about south-east and above it. On the Italian side of the massif are located north-east Macugnaga in the Valle Anzasca,south-east-south Alagna Valsesia in the Valsesia and Gressoney-La-Trinité in the Val de Gressoney, respectively, away from the summit. The different sides of the mountain greatly differ from each other. The Swiss west side is almost completely covered by large glaciers, tributaries of the large Gorner Glacier, descending progressively with gentle slopes and forming a large uninhabited glacial valley. The Italian east side consists of a wall overlooking Macugnaga, whose snows feed the Belvedere Glacier at its base. The southeast face, culminating at the Signalkuppe, overlooks the piedmontese Valsesia () and the Val de Gressoney in the autonomous region of Aosta Valley.
