The French Italian natural boundary, also known as the Franco-Italian border, is a geographical and political divide that separates France from Italy in the Alpine region. This boundary stretches for approximately 488 kilometers (303 miles) from the Mediterranean Sea to the border with Switzerland. The natural boundary is formed by the Alps, with several notable peaks and mountain ranges, including the Mont Blanc massif, the highest peak in the Alps, which stands at 4,808 meters (15,774 feet) above sea level.
Geological and Geographical Characteristics

The boundary is marked by several mountain passes, including the Col de la Madeleine, the Col du Mont-Cenis, and the Col de l’Iseran, which are all important transportation routes. The region is also home to several major rivers, including the Dora Baltea, the Arc, and the Tinea, which flow into the Mediterranean Sea. The natural boundary is not only a geographical divide but also a cultural and linguistic one, with the French-speaking population of France separated from the Italian-speaking population of Italy.
