A mountain pass is a route through a mountain range or over a ridge. If following the lowest possible route, a pass is locally the highest point on that route. Since many of the world's mountain ranges have presented formidable barriers to travel, passes have been important since before recorded history, and have played a key role in trade, war, and migration.
The Chang La (el. 5,360 m or 17,590 ft) is a high mountain pass in Ladakh, India. It is the third highest motorable road in the world.
The Chang La is on the route to Pangong Lake from Leh. The name literally means "Pass towards the South" or "Pass in the South" (Chang = south, La = Pass). It is falsely claimed that the pass is named after the supposed sadhu Changla Baba, a myth propagated by the dedication of a temple at the pass to the supposed Changla Baba. If any such sadhu exists or existed, he would have been named for the pass, rather than vice versa (since the name "changla baba" means the "baba of the southern pass". The small town of Tangste is the nearest settlement. The Changla Pass is the main gateway for the Changthang Plateau situated in the Himalayas. The nomadic tribes of the region are collectively known as the Changpa or Chang-pa.
