Rohtang Pass has historically served as a crucial trade route between the Kullu Valley and the Lahaul and Spiti regions. Its strategic importance dates back centuries, facilitating the movement of goods and people across the challenging Himalayan terrain. The name 'Rohtang' translates to 'ground of corpses' in the local language, a grim reminder of the dangers faced by travelers crossing the pass in harsh weather conditions. The pass has witnessed numerous expeditions and military movements throughout history. In recent times, the Indian government has improved the road infrastructure, making it more accessible to tourists. However, the pass remains susceptible to closures due to unpredictable weather, especially during the winter months.
