Situated about 51 km from Manali town at an altitude of 4,111 meters (13,400 ft.) on the highway to Keylong, is the Rohatang Pass. This is the pass which separates the picturesque and green valley of Kullu and Manali to the stark contradiction of barren brown mountains and deep valleys of stones and rocks. Rohatang is the place where the majesty of the mountains is at its height in splendour.
Rohatang in Tibetan language means a heap of dead bodies. And true to these words, Rohatang definitely would take toll of humans and property, every year due to its harsh weather. The pass becomes hazardous due to frequent avalanches. Although there is face over to the pass in summers and spring when the pass reels under beautiful flowers and birds and rare variety of butterflies.
There is a beautiful lake to the left of the pass known as Doshohar Lake. The Sonapani Glacier and the Gyephang La peaks offer a splendid view. At the height of the Rohatang pass one can see a small stone enclosure and a water spring, believed to be the source of River Beas.
Being the only route to enter the arid region of Lahaul and Spiti, trekkers and hikers can often be seen on the pass. It is closed in winters due to heavy snowfall and is open from April to September.
