Kuari Pass Trek in Winter

The Kuari Pass trek in winter is a different trek from the one people do in April. Same trail, same campsites, same view of Nanda Devi from the top. But in January the oak forest above Tugasi goes quiet under snow, the meadow at Khullara turns completely white, and the water bottle you left outside the tent is a block of ice by morning.

That's why so many people pick winter. Kuari Pass is one of the few Himalayan passes a first-timer can reach in deep winter, and it gives you proper snow, big mountains and cold, starry nights in under a week. It also asks more of you than the spring version. This guide covers the things most winter guides skip: how cold each campsite actually gets, what the wind does to that number, how short the days are, how the snow changes between morning and afternoon, and who should honestly wait for spring.

Winter Kuari Pass Trek at a Glance

Why Kuari Pass Is One of the Best Winter Treks in Uttarakhand

Most winter treks in Uttarakhand end at a summit viewpoint or a frozen lake. Kuari Pass takes you over a real Himalayan pass on the western rim of the Nanda Devi Biosphere Reserve, in the Chamoli district of Garhwal. It's part of the route Lord Curzon, then Viceroy of India, travelled in 1905, which is why you'll also hear it called the Curzon Trail.

The other reason is the view. From the pass on a clear winter morning, you look straight across at some of the highest peaks in India:

What the Kuari Pass Trek in Winter Looks Like, Month by Month

Winter arrives on Kuari Pass in stages. The snow line moves down the mountain week by week, and each month has its own character.

December: Clear Skies and the First Real Snow

Early December is cold and very clear. The post-monsoon haze is gone, and some of the sharpest views of the year come in these weeks. Snow usually settles on the upper trail and around the pass first, while the forest near Tugasi stays mostly dry. By the last week of the month, Khullara is often under a fresh layer.

December suits people who want snow on summit day without walking through snow for the whole trek. It's also the busiest winter month, especially over Christmas and New Year, so book those dates early.

January: Full Winter

January is the coldest month on the trail. Snow usually reaches well into the forest, and the climb from Gulling to Khullara becomes a snow walk for most of the way. Nights at Khullara regularly drop below -10°C. Mornings are still, the sky is usually a hard blue between snowfall spells, and the loudest sound around is your own boots on frozen snow.

Pick January if you want the full winter experience. It's also the month where your gear matters most. A good sleeping bag and a proper base layer make the difference between a cold night and a miserable one.

February: Deepest Snow and Kuari Pass Temperature in February

February brings the most precipitation of the winter in this part of Garhwal, and up high it all falls as snow. So even though January is colder, February usually has the deepest snow on the ground. Expect daytime highs of about 5 to 10°C at the campsites and nights of about -7 to -11°C at Khullara. Fresh snowfall can arrive with little warning and last a day or two.

Days get noticeably longer through February, which helps on summit day. The trade-off is soft, deep snow in the afternoons, which is why the summit push starts early while the snow is still firm.

Late November and March: The Shoulder Weeks

Late November can bring the first snowfall of the season, with dry forest below and a white pass above. March works the other way round. The lower trail thaws, the rhododendron buds start to show, and the meadows around Khullara often stay white. Both are good choices if you want some snow but milder nights than mid-winter.

Kuari Pass Winter Temperatures by Campsite

On this trek, where you are matters more than the date. From Joshimath to the pass you gain close to 2,000 metres, and every campsite is colder than the one below it. These are typical December to February ranges.

Ranges are typical for past winter seasons. A cold spell or a western disturbance can push nights several degrees lower.

One more thing these numbers hide is the sun. On a clear winter afternoon at Khullara you can sit outside in a single fleece, then need everything you own an hour after sunset. The drop is fast, often 12 to 15°C between mid-afternoon and night.

Wind Chill: Why -5°C Can Feel Like -12°C

The thermometer only tells you half the story. Wind strips heat from your skin, and on the open ridge below the pass a steady breeze is normal on winter mornings. The table below uses the standard wind chill formula used by weather services in North America to show what the air actually feels like on exposed skin.

What this means in practice: on a -5°C summit morning with a 20 km/h breeze, your face and fingers are dealing with about -12°C. That's why a windproof shell, a neck gaiter and two layers of gloves matter more on summit day than an extra fleece in your bag.

Winter Daylight: How Short the Days Are

Winter days on Kuari Pass are about four hours shorter than in June. We calculated sunrise and sunset for the pass using its coordinates. The mountains around camp block the sun for a while after sunrise and before sunset, so direct sunlight at camp starts later and ends earlier than these times.

Calculated for Kuari Pass (about 30.45° N, 79.58° E), Indian Standard Time.

Short days change how a winter trek runs. The group aims to reach camp by mid-afternoon, before the temperature drops. The summit push leaves Khullara around 6:30 AM, which in December and January is still before sunrise, so a headlamp with fresh batteries is essential. And evenings are long, which is why a good book, a deck of cards or a charged power bank earns its space in your bag.

Snow on the Trail: Where It Starts and How It Changes Through the Day

Every winter is different, but in a typical season the snow follows this pattern:

How the Snow Changes Between Morning and Afternoon

The same slope can feel like three different trails in one day. Knowing this pattern explains most of the decisions your trek leader makes.

•      Early morning (before 9 AM): snow is frozen hard. Great for walking, but icy on steep sections and on packed footpaths. This is when microspikes matter most.

•      Late morning to mid-afternoon: the sun softens the top layer. On deep snow you start sinking, sometimes up to the shin, and progress slows a lot. Gaiters keep the snow out of your shoes.

•      After sunset: meltwater refreezes into thin ice around camp, on rocks and on paths between tents. Walk carefully with a headlamp, even for a short trip to the toilet tent.

Heavy snowfall can also close the road from Joshimath to Tugasi for a day or two. If you're booking a winter batch, keep one buffer day in your travel plan on the way back. It saves a lot of stress with trains and flights.

What Winter Changes on Each Stage of the Trek

The route stays the same all year. Here's how winter changes each part of it.

Tugasi to Gulling

This is the gentlest stage, through village fields and then forest. In December it's often snow-free. In January and February you may meet snow in shaded sections of the forest, where the sun doesn't reach. It's the best stage to get used to walking on snow before it gets steeper.

Gulling to Khullara

The steadiest climb of the trek, through oak, rhododendron and deodar. In mid-winter this is where snow walking really starts. Short steps, a steady pace and a sip of water at every break work better than pushing hard and stopping often. Arriving at Khullara, the forest opens into a white meadow with the big peaks lined up in front of you.

Summit Morning: Khullara to Kuari Pass

The group usually leaves Khullara around 6:30 AM, in the dark or first light, while the snow is still frozen. Microspikes go on at camp. The trail rises steadily, and near the top the wind picks up and the view keeps widening until you step onto the pass. Your trek leader confirms the start time the evening before and will turn the group around if the ridge isn't safe. That call is part of trekking in winter, and a good team makes it without hesitation.

The Descent

Coming down is quicker but harder on the knees, and in winter it's also where most slips happen. Keep your microspikes on until the trail is clear of ice, shorten your steps and use your trekking pole. Once you drop into the forest, the snow thins and the walk becomes easy again.

How Cold Is It Inside the Tent?

A pitched tent with two people inside usually stays several degrees warmer than the air outside. That still means close to or below freezing on a January night at Khullara. Your sleep system keeps you warm, and only if you use it properly:

•      Change into dry clothes before you get into the sleeping bag. Damp socks and a sweaty base layer steal heat all night.

•      Wear a thermal cap and fresh woollen socks to bed. A lot of heat escapes through your head and feet.

•      Eat a full dinner and drink something hot. Your body needs fuel to stay warm through the night.

•      Keep tomorrow's water bottle inside the sleeping bag, or it will freeze.

•      Keep phone and camera batteries close to your body. Cold drains them fast.

•      If you need the toilet at night, go. Holding it in makes your body work harder to stay warm.

Cold Injuries: Early Signs to Watch For

Serious cold injuries are rare on a well-run winter trek, and they almost always start small. Catching the early signs is what keeps them small. Tell your trek leader straight away if you notice any of these in yourself or someone else.

Common Winter Mistakes on Kuari Pass

Most winter discomfort on this trek comes from a handful of avoidable mistakes:

•      Wearing cotton. A cotton T-shirt holds sweat and stays cold and wet for hours. Wear synthetic or merino next to your skin.

•      Starting the climb fully dressed. You heat up within 15 minutes and soak your layers in sweat. Start slightly cold and add layers at breaks.

•      Leaving water outside the tent. It freezes overnight. Keep one bottle in your sleeping bag and ask for hot water at camp.

•      Skipping sunglasses on cloudy days. UV reflects off snow even through cloud. Snow blindness usually shows up the evening after.

•      Tight shoes with thick socks. Tight shoes cut circulation and make cold feet worse. Try your shoes with winter socks before the trek.

•      Eating too little. Cold makes many people lose their appetite. Eat anyway. Your body burns a lot more energy staying warm.

•      No buffer day. Winter roads can close for a day. A tight train booking home turns a one-day delay into a real problem.

Who Should Do Kuari Pass in Winter, and Who Should Wait

Winter is a good fit if you:

•      Want your first proper snow trek and have done some regular fitness training

•      Can handle a few cold nights in a tent without it ruining your trip

•      Care more about snow and clear mountain views than flowers and green meadows

Consider spring or autumn instead if you:

•      Really struggle with cold, or have never slept outdoors below freezing

•      Have had knee trouble on descents. Icy downhill sections are harder on the joints

•      Can only travel on fixed dates with no buffer day

What to Wear on the Kuari Pass Trek in Winter

Think in layers. Several thin layers trap more warmth than one thick jacket, and you can take them off one at a time as you heat up on the climb.
