Kunzum Pass, Mountain pass in Lahaul and Spiti district, India

Kunzum Pass, at 4,551 m in the eastern Kunzum Range of the Himalayas, links the Lahaul and Spiti valleys on NH505, 122 km from Manali and 79 km from Kaza. From Batal on the Chandra River the road climbs through fifteen hairpin turns; from Losar on the Kaza side it follows the right bank of a Spiti tributary for 22 km through dry, semi-desert terrain.

Kunzum Pass links the Lahaul and Spiti valleys on the route from Gramphoo to Kaza, the subdivisional headquarters of Spiti. The NH505 crossing is 122 km from Manali and 79 km from Kaza. The Manali-Kaza road over the pass closes for seven winter months each year, while the Kaza-Pooh-Tabo-Shimla route stays open year-round. The NHAI plans a tunnel beneath the pass for all-weather connectivity.

Kunzum Mata is the presiding deity of the pass, and almost every vehicle passing through stops at her temple to bow before continuing. The shrine sits at the summit on the road between Gramphoo and Kaza, and drivers and travellers seek her blessing before the descent.

The Manali–Kaza road over the pass is normally open from June or July to October or November; opening and closing depend on weather and road repairs by the Border Roads Organisation. The Kaza–Pooh–Tabo–Shimla route stays open all year. From Batal the road climbs through fifteen sharp hairpin turns, and from Losar it runs 22 km up the right bank of a Spiti tributary.

A 15 km trek leads from the pass to Chandratal, the Moon Lake. The pass itself sits at 4,551 m, and the road from Batal on the Chandra River climbs to it through fifteen sharp hairpin turns.
