Mont Blanc ( meaning "White Mountain") is the highest mountain in the Alps. Mont Blanc, a huge mountain massif straddling the French and Italian border, is simply the most dangerous mountain in the world. Lots of people are killed and injured on it every year, and still they come in hordes to ascend to the roof of Europe. Why? Because it is popular for mountaineering, hiking, skiing and snowboarding. The 11.6 km (7¼ mi) Mont Blanc Tunnel runs beneath the mountain between Italy and France and is one of the major trans-Alpine transport routes.
