Chadar - Frozen River Trek


CHADAR TREK - Located at an altitude of around 12,000 to 13,000 feet in Leh Ladakh region, the beauty of Zanskar is like no place in India. It remains cut off from the rest of the world from the beginning of November till around April (around 4-6  months in a year).

The Zanskar river which takes its form onwards from Padum, after merging with its different tributaries, flows in a north-easterly direction through the dramatic Zanskar gorge and merges with the Indus river; the confluence being at Nimmu, just on the outskirts of Leh on the Leh-Kargil road.

As the bitter winter arrives in the valley, temperatures plummet drastically. With the river mostly flowing through deep gorges and with very little direct sunlight, the surface of the water freezes over during the coldest months of mid-January to mid-February. Zanskaris for generations, having been cut off during the winter months, trek on this ice surface to reach Leh for their emergency supplies, education and also for the different winter religious festivals that take place in Leh.

"CHADAR" refers to this blanket or ice sheet as the Zanskar River transforms itself from raging river into a white blanket of ice during winter, providing an incredible frozen spectacle for trekkers to be experienced.

The Coldest Trek in India

The Chadar Trek is the coldest trek in India, with temperatures plummeting to as low as -30C. During the day, the temperatures reach a cosy -10C and at night you can expect a chilly -30C. We at Adventure-Pulse provide you with Thick Alpine Tents, dual-layered sleeping bags (similar to the ones the army uses at their high-altitude posts) and plenty of hot water. This will ensure that at night, you can sleep comfortably. During the day, layering is the best way to keep warm.

The hardest aspect of the Chadar Trek is the cold and it requires some mental strength to bear. Although physically, the Chadar trek is less demanding than other high-altitude treks, it makes up for it with the sustained sub-zero temperatures.

Who do we recommend the Chadar Trek to?

The Chadar Trek is an easy trek with regards to the distance covered. It is the cold that is the major hurdle. We recommend this trek for individuals looking for a truly unique experience and who are looking to challenge themselves mentally and physically; this includes beginners and seasoned trekkers.

The moment you land at the Leh airport, one of the highest airports in the world, you will feel the fresh and crisp air, and a drastic drop in the temperature. The chill in the air will serve only as a preview of the temperatures during this winter trek. The average day temperatures we are expecting is about -15 & and average night temperature’s is -20 to -25. However, the night is spent in a cozy hotel resting and acclimatization.
We spend the day allowing our bodies to adapt to the high-altitude and soak in the local culture. One can visit some of the monasteries in and around Leh such as the Shey, Thiksey and Hemis. There is also the option of visiting the old Leh Palace and the Khardung La Pass (world’s highest Motorable road at 5,600m/18,400ft). Overnight at Hotel.
Our staff would help organize a medical checkup for you at the Leh district hospital during the day. This is now a mandatory requirement from the Leh district administration that every trekker going for the chaddar trek needs to undergo a compulsory medical checkup before embarking on the trek. If the parameters are found normal, you are given a go ahead for the trek and also need to purchase a compulsory medical insurance package from a private company listed by the administration.
We leave our hotel early morning by about 8 am and drive to the start point which is a 2 hour drive. Today is a long trek on the Chaddar. The trek leaders will give a briefing about the day, and give tips on how to walk on the Chaddar. It could be a cold and hard surface of slippery ice, or it can have a snow over it. Eventually you get used to walking on the Chaddar, which looks like a cross between gliding and skating. After passing Shingra Koma, you reach the camp-site for the day at Sumo. The Sumo campsite is at a bend in the river, surrounded by high peaks and walls of rock-faces which almost look man-made.
Today’s walk through the deep ravines of the Zanskar is stunning. The sublime walls of the mountains on either sides of the river keep the sunlight away from the Chadar for most part of the day. There are numerous caves in these mountains, big and small. Today is the day when you can see frozen waterfalls. The rocks below this waterfall are covered with moss, and this is the only greenery you’ll see on this trek.
Today is the most spectacular of all days on this trek. Walking on the river you cross deep gorges and reach a point where Juniper trees are covered with prayer flags. A few steps away lies the mother-of- all frozen waterfalls – a huge instance of suspended animation several feet tall and equally wide. You can see dozens of colors in this enormous ice structure as sunlight plays off its surface Right next to the waterfall is a bridge across the river which is a part of the summer-time road from Zanskar to Leh. The Naerak village lies several feet above the river.
After breakfast we begin our journey back to to Sumo/Bakula and set up camp. Sighting wildlife here is also a possibility - from the elusive snow-leopard to foxes and ibex -- keep a watch for the footprints of these creatures. Dinner and Overnight Stay at Campsite.
We start early in the morning and descend to the road head. We say goodbye to the chaddar, take stock of our bags and get into the vehicle waiting to take us back to Leh . Upon reaching Leh, we complete the check-in formalities and relax in your rooms.
As this unforgettable journey gets over, you depart from Leh. This trek also leaves behind a tremendous feeling of accomplishment – one of having undertaken and endured an extraordinary and challenging trek. The Chaddar trek will be a cherished memory for life.

The Chaddar trek is a trek where you need to be in good physical condition before you start the trek. Your body should be able to bear extreme cold caused by the subzero temperatures which can even drop down to as low as – 25 degree Celsius. You must be able to brisk walk / slow jog for 4 – 5 km before the trek starts. This makes your lungs strong and gives it ability to process less air for more work. It also helps the body to acclimatize better to the cold and low oxygen levels. Having taken several groups for Chaddar trek and many other high altitude treks, here’s what we recommend you to follow in order to get fit for the trek.
We recommend the following schedule to the participants
  1. Week 1/2: Develop a habit of getting up early in the morning and run / brisk walk for minimum 2 – 3 km, at least 3 – 4 days a week. This would represent 20 – 25 minutes of cardio. Also avoid taking elevators and start using the stairs instead. To start with, climb 3 – 4 floors each day to make your thigh muscles strong. If running is not your thing, you can cycle for about 30 minutes or swim for about 500 m, at least 4 times a week.

  2. Week 3/4: Being consistent with your exercise during week 1 and 2, increase your distance to 4 – 5 km and 5 times a week. You can also start with interval training which is a method of training the cardiovascular system by elevating the heart rate significantly and then allowing it to recover for a period before elevating it again. Ex. You may sprint to push your heart rate, then walk to allow it to calm down before starting the sprint again.

  3. Week 5/6: Strength & Endurance. After successfully following the schedule for the first 4 weeks, Just be consistent with your work out and increase the intensity slowly.

Consistency is the key. If you follow the above schedule thoroughly; you will be able to acclimatize better while at high altitude. Each and every time you go to a mountain, you must have the physical fitness to better enjoy the experience.
