Popular among tourists for its unparalleled natural beauty, Rohtang la also holds a strategic importance in the country because of its geographical location. It is the gateway to the Keylong district in the Lahaul valley region of Himachal Pradesh. This valley is otherwise completely landlocked and cannot be accessed in any other way.
Additionally, the pass also acted as a trade route between the people on the opposite sides of Pir Panjal range. So, it holds quite a lot of significance from the point of view of tourism, history, and geography.
