Winter Ladakh and the Chadar Trek: What You Actually Need to Plan For

Most people picture winter Ladakh as a place that's simply shut down — passes buried, roads gone, nothing to see until the snow melts. That's backwards. Winter is when a smaller, more deliberate kind of traveler shows up: photographers after the stark, near-monochrome landscape that summer's blue-lake tourists never see, and trekkers chasing the Chadar — the sheet of ice that, in a cold enough year, forms over the Zanskar River and turns it into a walkable trail. The phrase "in a cold enough year" is doing real work in that sentence. This is the one corner of Ladakh travel where the season itself has become genuinely unreliable — the trek was suspended entirely in the most recent winter it was attempted, because the river didn't freeze solidly enough to be safe. A winter Ladakh trip built around this needs more planning, more flexibility, and more caution than a normal weekend getaway, not less.

Getting to Leh in winter

Both routes into Leh by road close for the season: the Leh-Manali highway typically shuts by mid-to-late November and doesn't reopen until late May or June, and the Srinagar-Leh highway usually closes by late December or January, reopening from mid-April. Through the December- February window, flights into Leh's Kushok Bakula Rimpochee Airport are the only reliable way in, and winter departures are more prone to weather delays and cancellations than summer ones — build a buffer day into your itinerary on both ends rather than a tight connection.

The acclimatization rule applies with extra force in winter. Leh sits at roughly 3,500m, and standard medical guidance is at least two full rest days in town, with no real exertion, before you attempt anything strenuous — cold adds physical stress on top of the thin air, which is part of why trek operators typically build two to three acclimatization nights into Chadar packages before they'll let you start walking, often with a mandatory medical check at a Leh clinic before departure. Skipping this isn't a minor risk here; altitude sickness (AMS) is the most common way a Ladakh trip goes wrong, and winter cold makes recovery from it harder, not easier.

Permits: Leh vs. the restricted zones

Leh town itself requires no permit for Indian citizens. The moment you head toward Nubra Valley, Pangong Tso, Tso Moriri, or other areas close to the border, though, you're in Inner Line-restricted territory, and Indian travelers need to register and pay the Ladakh Environment & Development Fee online through the district administration's permit portal before entering — a process that's replaced the older standalone Inner Line Permit paperwork but still functions as a permit in practice. Foreign nationals need a separate Protected Area Permit arranged through a registered Leh agent. Fee amounts and the exact process have changed more than once in recent years, so confirm the current requirement and cost directly with your trek/tour operator or the official portal close to your travel dates rather than relying on last year's number. For the Chadar Trek specifically, the trek route itself and the relevant permissions are normally handled entirely by your registered operator as part of the package — one more reason not to attempt this independently.

The Chadar Trek: serious, certified, and not guaranteed

A few things about the Chadar are worth being precise about, because romanticized descriptions of "walking on a frozen river" undersell both the difficulty and the current uncertainty.

It requires a registered operator, not independent trekking. The All Ladakh Tour Operator Association (ALTOA) issues the no-objection certificate required for the trek to run at all, and operators run it with a fixed field team, porters, and safety protocol. There is no DIY version of this trek — book through an established, ALTOA-affiliated operator, and be skeptical of anyone offering it outside that system.
It's physically demanding but not technical — no ropes, crampons, or climbing skill required — but it does mean 8-9 days total (including Leh acclimatization) walking for hours a day on ice in temperatures that regularly drop to -20°C to -30°C at night. Operators generally expect solid cardiovascular fitness built up over the preceding two to three months, and a mandatory pre-trek medical check-up is standard.
It is not currently a guaranteed-to-run activity. The trek was suspended entirely partway through its most recent attempted season — the Zanskar River failed to freeze into the roughly 30-35km continuous, stable ice sheet that Leh's district disaster management authority requires for the trek to be declared safe, following an unusually mild winter. Whether it runs in any given year is decided close to the season itself, based on an on-ground ice recce, not something bookable with certainty months out. Treat any Chadar booking as conditional — confirm your operator's cancellation/refund policy explicitly covers a season-wide suspension before you pay, not just individual-trip weather delays.

If you're not doing the Chadar — or it doesn't run

Winter Ladakh is worth the trip even if the ice doesn't cooperate. Frozen Pangong Tso is a genuine draw in its own right when the Chang La road out to it is open (check current road status before committing — it closes after fresh snowfall and isn't guaranteed through the season), and Leh's monasteries run a quieter, more local winter calendar — Losar (Ladakh's New Year, generally December), Spituk Gustor (January), and Dosmoche (February) all bring masked cham dances to monastery courtyards, with none of summer's crowds. For photographers specifically, the stark, nearly tourist-free winter landscape is arguably a bigger draw than the trek itself.

When to actually book

Treat three to four months as the realistic minimum lead time for a serious Chadar attempt — not the six-to-ten-week window shorter regional getaways need. That accounts for ALTOA-operator slots (small batch sizes that fill up), winter flight capacity into Leh (limited and prone to price increases as departure nears), specialized cold-weather gear that may need advance arranging, and the operator's own confirmation that the season is actually running. If your target window is Ladakh's January-February ice season, start locking in an operator and flights by September or October of the preceding year — which, given how recently the trek was cancelled outright for lack of ice, is also enough runway to build in a fallback plan (frozen Pangong, monasteries, a straightforward winter Leh trip) if the Chadar doesn't run at all.
