Geographically, the Italian Alps begin in the northwest of the country at the border with France. The mountain chain forms a massive "arch" across northern Italy, spanning the provinces of Valle d'Aosta, Piedmont, Lombardy, Trentino-Alto Adige, Veneto, and Friuli-Venezia Giulia. The westernmost starting point is often considered the Col de Tende or the Cottian Alps near the French border. From there, the range progresses through the Graian Alps (home to the highest peaks like Mont Blanc and the Matterhorn) into the Central Alps of Lombardy, and finally into the Eastern Alps, which include the iconic Dolomites—a UNESCO World Heritage site known for its dramatic limestone spires. In 2026, the Italian Alpine region remains a premier destination for skiing, hiking, and mountaineering, with the city of Aosta serving as one of the most historic "gateways" to the range. The Alps act as a natural northern border, separating Italy from France, Switzerland, Austria, and Slovenia.
