Bara-lacha la, Mountain pass in Lahaul and Spiti district, India.
Bara-lacha la is a mountain pass located at approximately 4,900 meters elevation in the Lahaul and Spiti region. The pass connects the valleys of Himachal Pradesh with the plateau of Ladakh and serves as a key junction point on the Leh-Manali Highway.
The pass functioned as a major trade route for centuries, where merchants from Spiti, Ladakh, Zanskar, and Lahaul exchanged goods. This historical role as a commerce junction continues to define its importance today.
The name Bara-lacha derives from the geographical configuration of the summit, where multiple roads intersect to form essential transportation links between different regions.
The pass is open for travel only about six months per year, typically from April through October when snow melts. Road conditions remain variable even during this season, so travelers should prepare for possible delays and route changes.
The Chandra and Bhaga rivers originate near this pass and together form the source of the Chenab River. The Bhaga notably begins from Surya Taal Lake, a high-altitude mountain lake with nearly untouched waters.
