Zanskar Valley Winter Road — Chadar Trek Support Track via Frozen Zanskar River
The frozen river is the road.
For roughly six weeks each January and February, the Zanskar River freezes thick enough to walk — and in some stretches drive — forming the Chadar, one of the most surreal natural highways on earth. Traditional Zanskari villages like Padum and Zangla have been cut off by snow from the road network for centuries, and the frozen river was their lifeline long before any motor vehicle touched Ladakh. Vehicle support convoys now use sections of the frozen river and the adjacent boulder-strewn track to push supplies to Padum when the summer road over Pensi La is buried under metres of snow. Temperatures routinely hit -30°C at night. Ice shelves collapse without warning. This is not a trail you stumble into.
Only experienced drivers with properly winterised expedition vehicles — block heaters, synthetic oils rated to -40°C, recovery gear for ice — should attempt the motorised sections. The frozen river stretches themselves are impassable to vehicles in most years; the track hugs the river gorge walls on snowpacked dirt and rockfall debris. Fuel from Kargil or Leh only — carry full jerricans. No cell service in the gorge. Permits required for the inner line areas of Zanskar. Best window is mid-January to mid-February before daytime thaw weakens the ice. The reward is absolute: sheer canyon walls, total silence, and a scale of wilderness that recalibrates everything.

Frequently asked questions
What vehicle do you actually need to run this route — can a standard Mahindra Thar or Jimny handle it?
No. This requires a fully winterised expedition 4WD — think heavily modified Tata Safari, Toyota Land Cruiser 70 series, or equivalent with aggressive winter tyres, dual batteries, auxiliary fuel, and cold-weather seals rated well below freezing. A stock Thar or Jimny will not survive the sustained temperatures or the ice crossings without serious risk of being stranded 50+ miles from help.
When exactly does the ice get thick enough to drive on, and how long is the window?
The Zanskar River typically freezes to vehicle-bearing thickness in mid-to-late January, and the usable window closes by late February as temperatures rise. January–February is the only viable season — outside of this, the river is either partially frozen and unstable or completely thawed.
Do you need permits to drive this route, and how do you get them?
Yes. Foreign nationals require an Inner Line Permit (ILP) for Zanskar, obtainable online through the Ladakh administration portal or in person in Leh. Indian nationals don't need an ILP but should carry ID. Check current requirements with LAHDC Leh at lahdc.nic.in before departure — permit rules in this region have changed recently.
What's the most dangerous section and what makes it hard?
The gorge sections between Chilling and Pishu are the most serious — the river narrows, ice thickness becomes unpredictable, and there's no room to turn around if conditions deteriorate. Vehicles have punched through in warmer spells, and falling ice from canyon walls is a real hazard; multiple trekkers have died on the adjacent Chadar Trek in these zones.
There's no cell service on this route — how do expeditions handle emergencies 50+ miles in?
Satellite communicators (Garmin inReach or SPOT) are non-negotiable here — this is not a trail where you can hike out for help in January at altitude. Most serious expeditions run a two-vehicle minimum and carry a pre-arranged emergency extraction plan coordinated with contacts in Padum or Leh before departure.
