Neighbourhood Travel Desk: Rohtang Pass is a high mountain pass on the eastern Pir Panjal Range of the Himalayas around 51 km (32 mi) from Manali. It connects the Kullu Valley with the Lahaul and Spiti Valleys of Himachal Pradesh, India.
The pass provides a natural divide between the Kullu Valley with a primarily Hindu culture and the arid high-altitude Lahaul and Spiti valleys with a Buddhist culture. The pass lies on the watershed between the Chenab and Beas basins.
The pass is open from May to November. It is not particularly high or difficult to cross on foot by Himalayan standards, but it has a well-deserved reputation for being dangerous because of unpredictable snowstorms and blizzards.
This pass is an ancient trade route between the people on either side of Pir Panjal. The local name for this pass is a generic name of a pass. With the increase in Traffic at Rohtang Valley, environmentalists fear its impact on the fragile mountain ecology. A rise in average temperature and the consequent melting of glaciers are also issues of severe concern.
