The
trail from Yarkand crossed five other passes, of which the most feared was the
glacier, encumbered Saser-la, north of Nubra. Travellers from Tibet could take
one of two main routes. From the central part of the country, the Tsang-po valley,
they could pass the holy sites of Kailash-Mansarovar and reach Fartok, on a
tributary of the upper Indus, from where they followed the river down to Leh.
Trade with the pashm producing areas of western Tibet flowed by a more northerly
route, taking in the village of Rudok, a few miles into Tibet, and from there
across the 18,300 feet (5,578m ) Chang-la to the Indus, and so to Leh.
Baltistan, joined administratively with Ladakh for 100 years, was linked to
it either via the Indus up to its confluence with the Suru-Shingo river, and
on up to Kargil; or by the Chorbat-la pass over the Ladakh range, the trail
dropping down to the Indus 40 km below Khalatse, and following the river up
to Leh.
The two main approaches toLadakh from south of the Himalaya are roughly the
same as today's motor roads from Srinagar and Manali. The merchants and pilgrims
who made up the majority of travellers in the premodern era, travelled on foot
or horseback, taking about 16 days to reach Srinagar; though a man in hurry,
riding non-stop and with changes of horse arranged ahead of time all along the
route, could do it in as little as three days.
