Chadar Trek

The Chadar Trek is one of the world's most distinctive winter walks — 90 km out-and-back along the frozen Zanskar River through a narrow Himalayan gorge in Ladakh, walked only in late January and February when the river ice (the *chadar*, or "blanket") is thick enough to bear weight. For the Zanskari people, the chadar has been the only winter route in and out of their otherwise road-isolated valley for centuries; for foreign trekkers, it's a 8–9 day expedition into an ice-walled canyon at –25 °C.

The trek starts at Chilling, at the end of the Leh–Chilling road, and follows the Zanskar river downstream into the gorge. The river ice is rarely uniform — some days you walk on smooth, glassy chadar a metre thick; other days the ice has broken and the route detours along narrow ledges high above the river or wades through ankle-deep slush in gum-boots. The canyon walls rise 600 m on both sides, often within touching distance, with frozen waterfalls hanging like blue chandeliers from the cliffs. Camp is in shallow caves carved by the ice into the canyon walls — Tilad Do, Shingra Koma, Tibb. The turnaround point is Nerak, a small Zanskari village with a frozen waterfall that's the trek's photo destination, then the same route reversed for the descent.

The Chadar is open only mid-January to mid-February — the window when the river ice is reliable. Outside that, the chadar breaks and the route is impossible. The trek is climate-change-affected — over the past decade the ice has formed later and broken earlier, and there have been winters when the trek was officially cancelled. The Indian government requires all foreign trekkers to use a registered Leh operator, with mandatory porter ratios, evacuation insurance, and medical clearance from a Leh doctor before starting. Temperatures inside the gorge are routinely –20 °C to –30 °C and high winds can drop the apparent temperature below –40 °C. This is genuine expedition-grade trekking; the lack of altitude (max 3,850 m) is the only thing making it accessible to non-mountaineers.
