which mountains would you cross to travel from northern italy to switzerland
Alps The Alps are a crescent shaped geographic feature of central Europe that ranges in a 800 km (500 mi) arc from east to west and is 200 km (120 mi) in width. The mean height of the mountain peaks is 2.5 km (1.6 mi).[10] The range stretches from the Mediterranean Sea north above the Po basin, extending through France from Grenoble, and stretching eastward through mid and southern Switzerland. The range continues onward toward Vienna, Austria, and east to the Adriatic Sea and Slovenia.[11][12][13] To the south it dips into northern Italy and to the north extends to the southern border of Bavaria in Germany.[13] In areas like Chiasso, Switzerland, and Allgäu, Bavaria, the demarcation between the mountain range and the flatlands are clear; in other places such as Geneva, the demarcation is less clear. The countries with the greatest alpine territory are Switzerland, France, Austria and Italy.
Swiss Alps The Alps cover 65% of Switzerland's total 41,285 square kilometres (15,940 sq mi) surface area, making it one of the most alpine countries. Despite the fact that Switzerland covers only 14% of the Alps total 192,753 square kilometres (74,422 sq mi) area,[2][3] 48 out of 82 alpine four-thousanders are located in the Swiss Alps and practically all{number(s) needed} of the remaining 34 are within 20 kilometres (12 mi) of the country's border.
