Bara-lacha la also known as Bara-lacha Pass, or Bārā Lācha La, (el. ) is a high mountain pass in the Zanskar range of Northern-India, connecting Lahaul district in Himachal Pradesh to Leh district in Ladakh. Rail-cum-road tunnels are being constructed under the Bara-lacha la, Lungalacha La (84 km north of Bara-lacha la) and Taglang La (171 km north of Bara-lacha la) to cater for the traffic on existing NH3 Leh–Manali Highway & under-construction Bhanupli–Leh line. The two headwaters of the Chenab River, Chandra and Bhaga, originate near the Baralacha Pass. The Bhaga river originates from Surya taal lake, which is situated a few of kilometers from the pass towards Manali. The Chandra originates from glacier in this region. The native name of Chenab, "Chandrabhaga", represents the union of Chandra and Bhaga rivers downstream. The pass also acts as a water-divide between the Bhaga river and the Yunam river.

On the northwest originates the Bhaga River while the Chandra flows south-east. Below the Baralacha-la is an emerald lake, the Suraj tal (Sun lake), the source of the river Bhaga. "Mr. Shaw thus describes the region: "The Bara Lacha is the boundary between two separate regions distinguished by their physical characteristics. That which we have already passed through may be called the true Himalayan region. Here the gigantic ranges are covered with perpetual snow, furrowed by glaciers, and they arise from amid dense forests which clothe their flanks up to a certain elevation. They are separated by deep gorges, whose sides are precipices, and though which large rivers flow. In fact the scenery is Alpine. Henceforward, however, we must bear in mind that we are in the barren or Tibetan region, where green spots are about as rare as
