Chadar Trek 2026: Complete Itinerary, Tips, Permits
There is a stretch of the Zanskar River in Ladakh that, on most days of the year, is a roaring torrent slicing through canyon walls that rise hundreds of metres on either side. For a few weeks each winter, when the temperature drops far enough and holds long enough, that torrent falls silent under a thick white sheet. The locals call it Chadar. A blanket. And for centuries, it was the only road out.
Walking the Chadar is not a trek in any conventional sense. There is no trail. There are no switchbacks, no forest cover, no gradual ridge climb. You walk on a river. Some of the ice holds you at three metres above the flowing water below. Some of it groans and shifts beneath your boots. On certain sections, where the sheet has fractured, you wade through ankle-deep rushing water in sub-zero air and keep moving because stopping is not an option.
This guide is built from first-person accounts, on-ground research, updated permit information, and the kind of detail that only matters when you are actually on the ice. Read it in full before you book a single thing.

What the Chadar Actually Is
The word Chadar translates directly from Hindi and Ladakhi as sheet or blanket. It refers to the layer of ice that forms over the Zanskar River each winter when sustained sub-zero temperatures cause the surface to freeze from bank to bank. The river does not freeze uniformly. Thick plates form in calmer sections. Other parts remain open, with water running over existing ice and refreezing in new patterns overnight. The route changes from year to year, sometimes from day to day.
The Zanskar River is a major tributary of the Indus. It flows through some of the deepest and most isolated gorge terrain in the western Himalayas. For the villages of the Zanskar Valley, including Nerak, Lingshed, and Padum, the river gorge is effectively a wall that cuts them off from the rest of Ladakh every winter. The Chadar was, and in a diminishing number of years still is, the only path through that wall when roads are buried under snow.
The trek as a tourist route runs from Tilad Sumdo near the village of Chilling, approximately 65 km from Leh, to Nerak village and back. The total on-foot distance is between 60 and 70 km depending on route variations and ice diversions. You travel east through the gorge, deeper into the Zanskar, and then return the same way.
Walking on Chadar is not the hardest thing you will do physically. It is one of the hardest things you will do mentally. The cold does not ask permission. It arrives in your joints, behind your eyes, inside your lungs, and it stays there.
10 Things Most Chadar Trek Guides Will Not Tell You
Every competitor article will give you the standard route points and a generic packing list. What follows is the kind of detail that changes how you prepare and how you experience the trek.
-
01
The Chadar is a living surface that changes beneath you The ice is never static. It forms, fractures, refreezes, and shifts as the river continues flowing underneath. A section you cross safely on day two of your outward journey will look and behave differently on your return. There are documented cases of trekkers crossing a stable-looking surface only to have it give way at the edges. Your guide is reading micro-cues constantly: the sound of the ice, the colour, the texture. When your guide changes direction suddenly, follow without questioning.
-
02
The snow leopard is a genuine presence on this route The Chadar route passes through the buffer zone of Hemis National Park, which has one of the highest snow leopard densities in the world. Trekkers have spotted paw prints in the snow along the ice banks, particularly in the stretch approaching Tibb Cave. You will not see the animal itself in almost all likelihood, but the prints are real. Hemis National Park covers 4,400 square kilometres and supports populations of the leopard, Himalayan wolf, red fox, and a significant population of blue sheep (bharal) which serve as primary prey.
-
03
The Nerak bridge is over a thousand years old Just before the Nerak campsite, there is a wooden bridge spanning the Zanskar gorge that connects the trekking route with Nerak village above. Local accounts describe this bridge as more than a thousand years old, rebuilt over generations using the same materials and joinery techniques. It is the gateway through which Zanskari villagers carry goods on their backs to reach the trading posts of Leh during summer. Most trekkers cross it without knowing what they are touching.
-
04
Nerak village sits 600 metres above where you camp When trekkers talk about reaching Nerak, they are almost always referring to the campsite near the frozen waterfall at river level. The actual Nerak village is approximately 2,000 feet above the Zanskar riverbed. Very few trekkers make the uphill detour to the village itself, which means you can spend a morning there in near-complete solitude. The villagers follow Tibetan Buddhism and live in mud-brick homes that are designed to face south for maximum winter sun exposure, a passive solar technique refined over centuries.
-
05
There is a naturally flowing spring that never freezes at Tsomo Paldar Between the starting point and Tibb Cave lies the campsite at Tsomo Paldar. Here, a spring known locally as Tsomo Paldar emerges from the rock face and flows year-round without freezing, even in the deepest winter. The Zanskari guides and porters consider this spring to have significance in local folk tradition. The water is clean, very cold, and if your guide permits it, worth filling your flask from.
-
06
Tibb Cave is not one cave Most articles describe Tibb Cave as a single shelter. In reality, the Tibb section of the gorge features a series of natural overhangs and shallow caves carved into the canyon wall by centuries of river action and erosion. Local porters have used specific caves here as overnight shelters for generations, with some showing faint evidence of fire use on the rock ceiling. The cave system at Tibb is extensive enough that large groups are sometimes split between different shelters depending on conditions.
-
07
The penguin walk is biomechanically specific, not a joke First-time trekkers are told to walk like a penguin and often treat it as a funny instruction. The technique is actually based on real physics of ice movement. A waddling gait with a low centre of gravity, feet slightly apart and toes turned outward, distributes your weight over a larger surface area and reduces the pressure load on any single point of ice. It also shifts your centre of gravity toward your heels, which helps you recover from forward slips. Guides who have completed many seasons on the Chadar are immediately identifiable by the near-unconscious efficiency of their ice gait.
-
08
The Nimu-Padum-Darcha Road is reshaping the traditional route The Border Roads Organisation is actively constructing the Nimu-Padum-Darcha Road through the Zanskar gorge under Project Yojak. In 2024, portions of the Chadar route were truncated because construction activity had altered sections of the ice and the canyon walls. This road, when fully operational, will end the Chadar's function as a winter lifeline for Zanskar villages. It will also permanently alter the terrain of the trek. The cultural premise of the journey, walking the route that connected isolated communities to the outside world, will change irrevocably.
-
09
The Confluence at Nimmu is a navigational and cultural landmark The drive from Leh to the trek's starting point passes through Nimmu, where the Zanskar River meets the Indus. This confluence is visible from the road and is one of the most striking natural meeting points in all of Ladakh, where the milky grey glacial water of the Zanskar crashes into the blue-grey current of the Indus. In Buddhist cosmology associated with the Zanskari people, rivers and their confluences carry spiritual significance. Many trekking groups pass this spot in the dark before dawn without ever seeing it clearly.

The ice colour tells you more than any guide will explain Blue ice on the Chadar indicates old, dense, air-bubble-free ice that has been compressed over time. It is the most structurally solid. White or opaque ice contains trapped air bubbles and is newer formation, generally less stable. Grey or dark-patched ice near the shore often indicates water movement underneath and should be avoided. Green-tinged ice near spring inflows is typically strong but worth confirming with your guide. Reading ice colour becomes second nature within a day or two and transforms the visual experience of the trek from scenic to genuinely informative.
Day-by-Day Chadar Trek Itinerary
This is a standard 10-day itinerary covering Leh arrival, acclimatization, the full trek to Nerak, and return. Some operators run compressed 8-day versions by skipping the second rest day in Leh, but this is not advisable for first-timers at altitude.
Day 1
Arrive in Leh
Flights from Delhi take roughly one hour and land at Kushok Bakula Rimpochee Airport. The altitude hit is immediate. Do not plan any activity for the afternoon. Rest completely, drink warm fluids, and avoid any exertion. Leh in January is cold even in the market, with daytime temperatures hovering around minus 5 to minus 10 degrees Celsius. Acclimatization is the only objective today.
Day 2
Acclimatization in Leh
Rest continues. Short walks around the market are acceptable but no strenuous activity. Many trekkers visit Shanti Stupa in the late afternoon, a gentle uphill walk that serves as a light test of how the body is responding to altitude. The mandatory government medical check is typically scheduled on this day or the next at the Tourist Information Centre. This check is not optional. Without a fitness certificate from the designated medical camp, you cannot obtain your permits to trek on Chadar.
Day 3
Acclimatization and Permit Day, Leh
The final day in Leh is spent completing the permit process. Your trek leader or operator will coordinate the Wildlife Permit, the ALTOA clearance, and the environmental fee payment. Gear check happens in the evening. Sleeping bags are tested, layers inspected, and gumboots or trekking boots fitted. The drive to Tilad Sumdo begins very early the following morning, so an early night is necessary.
Day 4
Leh to Tilad Sumdo, Trek to Shingra Yokma
The drive along the Indus River is spectacular in winter dawn light. You pass through Nimmu where the Zanskar and Indus converge, then follow the Zanskar upstream to Chilling and onward to Tilad Sumdo. Once out of the vehicle and on the ice for the first time, your guide will demonstrate the ice walking technique. The first section of Chadar is relatively straightforward. Camp at Shingra Yokma on the riverbank or on the ice itself depending on conditions.
Day 5
Shingra Yokma to Tsomo Paldar
This is the day the Chadar begins to reveal its true character. The gorge walls rise above you in shades of burnt orange and grey. The canyon narrows in places to as little as five metres of passable ice between cliffs. You encounter the first serious frozen waterfalls on the canyon walls, formations of turquoise and white ice that have been building since November. At Tsomo Paldar, you reach the spring that flows year-round without freezing. Camp here for the night.
Day 6
Tsomo Paldar to Tibb Cave
The longest and most technically demanding day of the outward journey. The gorge becomes increasingly dramatic. You navigate ice that changes texture every hundred metres. Some sections require walking along the frozen cliffs because the central ice is too thin. Others are wide, flat, and glassy. Tibb Cave appears in the late afternoon as a series of natural overhangs that the canyon wall provides. This is one of the coldest nights of the trek since the caves channel wind. Sleeping bag performance matters here.
Day 7
Tibb Cave to Nerak
This is the day most trekkers describe as transformative. The landscape opens slightly and the ice becomes more varied in colour and texture. In the final two kilometres before Nerak, the gorge walls crowd in again and the air becomes noticeably colder. The frozen waterfall at Nerak comes into view from a distance, a massive column of blue-white ice that has formed over the entire height of the cliff face. The sight of it after days in the gorge is startling. The campsite sits at the base of this waterfall. The ancient wooden bridge connecting to Nerak village is 200 metres beyond.
For those who want to visit the actual Nerak village, a steep climb of roughly 600 metres gain begins from the bridge. It takes about 90 minutes one-way and is worth every step for the panoramic view back down the gorge and the experience of the village itself.
Days 8 to 10
Return to Tilad Sumdo via Same Route
The return follows the same river route in reverse. It is not a repeat experience. The ice has changed since you passed through. Sections that were solid four days earlier may have new fractures or may have been swept clean by water overflow. The light is different in the afternoon versus the morning. Your body has adapted and your ice walk has improved enough that you move with more confidence. The return is physically easier but the changing ice keeps it mentally fresh. Nights at Tibb Cave and Tsomo Paldar before reaching Tilad Sumdo and driving back to Leh.
Permits, Rules and the Medical Check
The Chadar Trek has a more layered permit process than most Himalayan treks in India. This is because the route passes through the Hemis National Park buffer zone, involves extreme environmental conditions, and historically saw safety incidents when it operated with fewer controls.
Documents and Permits Required
You need a Wildlife Permit from the Hemis National Park authority, an ALTOA (All Ladakh Tour Operators Association) permit, an environmental clearance fee, and a medical fitness certificate from the government medical camp operated specifically for Chadar trekkers in Leh. Foreign nationals also require an Inner Line Permit for Ladakh.
The combined permit cost is approximately Rs 6,000 to Rs 10,000 per person. This is paid directly to the relevant authorities at Leh, not to your trek operator, and is over and above the operator package cost. Offloading of backpacks costs an additional Rs 5,000 per person paid separately at Leh if you use this service.
Rules on the Ice
Trekking without a licensed guide is not permitted. The trek must be done in registered groups. Solo or independent trekking on the Chadar is not allowed under current regulations. Littering on the route carries penalties. Defecation on or near the ice is prohibited and designated points are established along the route for waste management. Fires on the ice are not permitted due to the risk of melting and structural compromise.
Verifying Trek Status Before You Book
Given the suspensions in 2025 and 2026, the most important step before booking flights or packages is to confirm that the trek is officially open for the season. Check with the Leh DC office, ALTOA, or your registered trek operator for a status confirmation. No legitimate operator will confirm a departure without official clearance. The ALTOA reconnaissance team visits the route multiple times before a season opens and submits a report to the District Administration before trekkers are permitted to begin.
Climate Change and the Chadar's Uncertain Future
This is the section that most Chadar guides skip or treat in a single sentence. It deserves honest and extended attention because it fundamentally changes how you should plan and think about this trek.
The winter of 2026 was the warmest on record in Ladakh over the past eight years. The average temperature between December and February was minus 8.6 degrees Celsius, significantly warmer than previous winters. Meteorological data from the Leh centre recorded 80.3 mm of summer rainfall in August 2025, the highest in 15 years. This irregular precipitation pattern disrupts the snowfall accumulation that sustains the cold conditions required for ice formation. Sonam Lotus, Director of the Meteorological Centre in Leh, has explained that stable Chadar formation requires not only sustained sub-zero temperatures but consistent winter snowfall to maintain prolonged cold conditions. When both are absent, the river fails to produce the thick, continuous ice sheet that the trek requires.
The trek has now been suspended or truncated in 2024, 2025, and 2026. For 2024, construction on the Nimu-Padum-Darcha Road caused route truncations. For 2025 and 2026, the Zanskar River simply did not freeze adequately. SDRF Inspector Tsering Angchuk described it in April 2026 as unprecedented in his five years of conducting pre-season reconnaissance on the river.
The human cost is also significant. A single Chadar season is worth roughly three lakhs in income to a guesthouse owner in Leh. Guides, porters, cooks, jeep drivers, and small hospitality operators whose entire winter livelihood depends on this one trek have faced back-to-back difficult years. The Zanskari community, for whom the Chadar was never tourism but necessity, faces a parallel loss as the river ceases to be a reliable winter path just as a new road is being cut through the same gorge.
None of this means the Chadar is finished. In a good winter with adequate snowfall and sustained cold, the river will still freeze. The question is no longer whether it will happen but how reliably it can be predicted, and what a season that does happen is worth experiencing given that it may become rarer.
What to Pack for the Chadar Trek
The Chadar is not a high-altitude climb. You will not go above 3,400 metres. But the sustained cold, the absence of shelter from wind along the gorge walls, and the wet-cold combination of ice walking create gear requirements that are unforgiving. Underpack warmth and you will spend the trek suffering rather than experiencing.
The Layering System
Your base layer must be moisture-wicking, not cotton. Merino wool or synthetic polypropylene thermals are the correct choice. Cotton retains moisture and becomes a cold trap. You need two to three sets of thermal tops and bottoms to allow drying between uses. Over the thermal base, a mid-weight fleece provides insulation. Over that, a down jacket rated to at least minus 20 degrees Celsius. The outer shell must be windproof and water-resistant to handle blowing snow and occasional spray from broken ice sections.
Costs Breakdown 2027
| Item | Approximate Cost (INR) |
|---|---|
| Delhi to Leh return flights (economy, advance) | 8,000 to 15,000 |
| 9 to 12 day organized trek package | 22,000 to 40,000 |
| Wildlife permit plus ALTOA plus environmental fee | 6,000 to 10,000 |
| Backpack offloading service | 5,000 |
| Gear rental in Leh (sleeping bag, gumboots, jacket) | 3,000 to 5,000 |
| Leh accommodation (pre/post trek, 3 nights) | 2,500 to 6,000 |
| Personal expenses, medicine, insurance | 3,000 to 8,000 |
| Estimated total | 50,000 to 90,000 |
Travel insurance that includes helicopter evacuation is strongly recommended. An emergency helicopter extraction from the Zanskar gorge is the only viable rescue option in serious injury or medical emergency situations. The cost of a private rescue helicopter without insurance can exceed Rs 2 to 4 lakhs.
Physical Preparation for the Chadar Trek
The Chadar is deceptive in its elevation profile. You gain very little altitude over the course of the trek, which might suggest low physical demand. The actual challenge is cardiovascular endurance at altitude, sustained cold exposure that depletes energy reserves faster than temperate conditions, and the specific muscular demand of walking on ice for 6 to 8 hours per day on an unstable surface.
The standard recommendation is to be able to run 3 to 4 km in under 30 minutes or walk uphill on a 10-degree incline for at least 45 minutes without significant distress. But these are minimum thresholds, not preparation targets. A more realistic preparation for 6 to 8 weeks before departure would include daily walks of 45 to 60 minutes on uneven terrain, stair climbing sessions three times per week, and if possible, some exposure to cold conditions through cold water immersion or outdoor exercise in low temperatures.
Trekkers who have done at least one previous Himalayan trek above 10,000 feet will acclimatize more predictably in Leh. The medical check is a filter for obvious risks but it does not catch every case of poor fitness. The main burden is on you to arrive genuinely prepared.
Frequently Asked Questions
What is the best time to do the Chadar Trek?
The window is traditionally late January through mid-February. However, due to climate change causing inadequate ice formation in 2025 and 2026, the actual operational dates vary each year and must be confirmed with the Leh DC office or ALTOA before booking. Never book flights before receiving season confirmation.
Can beginners do the Chadar Trek?
Not comfortably. The elevation itself is not extreme, but walking on ice for 6 to 8 hours daily in minus 20 to minus 30 degree Celsius temperatures requires prior cold weather experience and good physical conditioning. Completing at least one Himalayan trek above 10,000 feet before attempting Chadar is strongly recommended.
What happens if the Chadar Trek is cancelled after I book?
This is now a real and documented risk given the suspensions of 2025 and 2026. Most reputable operators offer partial or full refunds if the trek is suspended by official order. Check the cancellation and weather policy of your specific operator before paying. Travel insurance that covers trip cancellation due to natural events is advisable.
Is mobile connectivity available on the Chadar Trek?
There is no mobile network coverage on the Chadar route beyond the starting point at Tilad Sumdo. BSNL has the most limited coverage in Leh itself. For the duration of the trek you are completely offline. Some operators carry satellite communication devices for emergency use only.
Are women-only or solo women groups available for the Chadar Trek?
Yes. Several established operators including Bikat Adventures and Indiahikes organize departures that cater specifically to solo women trekkers, with women trek leaders available. The Chadar is a fully feasible trek for women and solo travellers as long as the group departure and guide requirements are met.
What food is available on the Chadar Trek?
Most organized treks provide vegetarian and egg-based meals. Breakfast includes porridge, eggs, and bread with hot tea. Lunch is typically packed food eaten on the ice, including chapati, pickle, and dry snacks. Dinner is a hot cooked meal at camp with rice, dal, and vegetables. Hot soup is served at almost every meal as part of cold management. Non-vegetarian meals are generally not available on the trek route itself.
What is the difference between Chadar Trek and Zanskar River Trek?
They refer to the same route. The Chadar Trek describes the winter walking experience on the frozen Zanskar River. The Zanskar River Trek sometimes describes either the same winter route or, in a summer context, the rafting and trekking expeditions along the Zanskar when the river is flowing. In most current usage, Chadar Trek and Zanskar frozen river trek are interchangeable.
