A mountain pass comprises of a route through a mountain range and its exact location is denoted by the highest location in terms of altitude within that route. This highest location within the route through the mountain range is also the lowest route in terms of altitude that can be travelled in relation to the mountains around the route.
The formation of mountain passes between mountain peaks might occur during the formation of the mountain range or they may be formed due to the action of glaciers, running water, or with the help of precipitation in the form of rain or snow. While a mountain pass through a ridge can be as narrow as 20 feet, in a large mountain range can occur in the form of a large valley. Semo La in the Tibetan Plateau is the highest confirmed mountain pass in the world with an elevation of about 18,258 feet (World Landforms, 2015).
Some of the highest peaks in the world are present in the Himalayas, which lie south of the Tibetan Plateau. India also has many other mountain ranges such as the Karakoram Range, the Aravali Range and many other minor ranges in the Deccan Plateau. Here we shall engage in a discussion of some of the prominent mountain passes in India that stand out.

This road is not as much a tourist attraction as Khardung La however, as the road through Chang La is also a very dangerous road, with numerous sheer cliffs at great altitudes. On top of this there is a great deal of snow on the road almost throughout the year which can make the road slippery at times.
