Taglang La, Mountain pass in Ladakh, India.

Taglang La, also called Tanglang La, is a mountain pass at 5,328 metres in Leh district, Ladakh, on the NH3 Leh–Manali Highway. The road crosses bare, rocky slopes above the treeline, and the pass is open only seasonally, from June to September.

Taglang La lies on the NH3 Leh–Manali Highway in Leh district, Ladakh. Rail-cum-road tunnels are being built beneath the pass, along with those under Lungalacha La 87 km south and Bara-lacha la 171 km south, to carry traffic from the existing NH3 and the under-construction Bhanupli–Leh line. Once that railway is completed, the station at the pass, at 5,256.25 m per SRTM data, would become the world's highest railway station, overtaking Tanggula station in Tibet at 5,068 m.

Nomadic herders still pass through here seasonally with their sheep and goat flocks searching for pasture across the mountains. You might encounter these herds moving along the road, a reminder of how people have adapted to life at extreme altitudes.

The road is often closed or difficult to travel during winter months, so plan your visit for the warmer season when it is passable. Bring warm clothing, adequate water, and food supplies since the nearest settlements are far away and services are minimal.

Taglang La's signboard elevation matches SRTM satellite data, but its old claim as the world's second-highest motorable pass no longer holds: by 2015 it ranked twelfth, as higher passes were built. Rail-cum-road tunnels are under construction beneath it, Lungalacha La and Bara-lacha La for the NH3 and Bhanupli–Leh line.
