Geography of Leh

Mountains dominate the landscape around the Leh as it is at an altitude of 3,500m. The principal access roads include the 434 km Srinagar-Leh highway which connects Leh with Srinagar and the 473 km Leh-Manali Highway which connects Manali with Leh. Both roads are open only on a seasonal basis.[17] Although the access roads from Srinagar and Manali are often blocked by snow in winter, the local roads in the Indus Valley usually remain open due to the low level of precipitation and snowfall.
