Sangam (Indus–Zanskar Confluence)

The Sangam near Nimmu is the confluence of the Indus and Zanskar rivers, about 35 km west of Leh in Ladakh, where the Zanskar flows into the Indus, one of the great rivers of Asia. At the Sangam the two rivers carry different sediments, so for a stretch they run side by side in clearly different colours before mixing downstream.

Sangam means confluence in Hindi. In summer the Indus usually runs a clearer blue green, while the Zanskar, fed by glacier melt from the Zanskar range, is a muddier brown or grey green; the contrast is sharpest from June to September. The Zanskar gorge above the confluence is the route of the famous Chadar trek in winter, when trekkers walk on the frozen river. In summer the Sangam is a popular end point for white-water rafting on the Zanskar, and gentler rafting runs start on the Indus nearby. A viewpoint on the highway above gives the best view of the two colours against the bare mountains.

What to wear

There is no dress code at the Sangam. The site sits at about 3,100 metres in open sun, so wear sunglasses, a hat and sunscreen, and bring a windproof layer. If you go down to the water or raft, wear quick-drying clothes and sandals with straps; rafting companies supply wetsuits and life jackets. Ladakhi villagers in Nimmu may wear the goncha, the traditional long woollen robe tied with a sash.

Local food to try

Dhabas and small cafes at Nimmu and the viewpoint serve thukpa noodle soup, skyu (a hearty stew of thumb-pressed wheat pasta and vegetables), momos, khambir flatbread with apricot jam, and salty butter tea. Rafting operators often include a simple lunch of rice, dal and vegetables. Vegetarian food is the norm along this road.
