Rohtang Pass, Mountain pass in Himachal Pradesh, India

Rohtang Pass is a high mountain pass at 3,980 m (13,058 ft) on the eastern end of the Pir Panjal Range, 51 km from Manali. The pass forms a broad V-shaped saddle between steep, dark grey rocky slopes, with thick white snow filling the cleft and spilling downward in broken patches and long narrow streaks over the darker rock. The snow alternates with bare rock, creating a jagged white-and-grey upper edge against the sky, while the lower slopes are mostly bare, dark grey rock and scree with a few thin snow remnants.

Traders used this route for centuries to move between valleys, with many losing their lives to sudden snowstorms. The opening of the Atal Tunnel in 2020 provided safe winter passage for the first time.

The name Rohtang comes from the Persian words ruh and tang, meaning "pile of corpses", a reference to travellers who died crossing in snowstorms. The pass also marks a cultural border: the Hindu Kullu Valley lies to the south, the Buddhist Lahaul and Spiti valleys to the north.

The road over the pass is usually open from May to November, though snow and ice change conditions depending on the season. Warm clothing is necessary even in summer, as temperature drops quickly and strong wind is common.

At the top, the pass marks a watershed dividing two major river systems, with the Beas emerging underground to the south. The Chandra flows westward on the northern side and later forms the Chenab.
