Ladakh
is known as the land of the high passes, also known as La's. Until the
advent of the aircraft, Ladakh could only be reached via high passes, one
of the reasons of this region's remote look. The Zoji La pass connecting
it to Kashmir lies at 14,000 ft and is the lowest approach from the west.
The southeast approach has to cross the 18,200 ft high Tanglang La and to
the north lie the passes of Saser La and the Karakoram, gateways to
Central Asia, from where trading caravans used to come in the ancient
times.
