Auden’s Col is a pass that connects Rudugaira Valley to the Bhilangna Valley. The Itinerary & route of Auden’s Col Trek includes 3 passes and the infamous Khatling glacier. The Col (saddle-shaped pass joining two surrounding peaks) connects Jogin I (6465 m) and Gangotri III peak(6580 m).

Auden’s Col Trek

The pass is situated at an altitude of around 5400m above sea level. On the opposite side, it also connects two glaciers. The first one is the Khatling Glacier, the other one is the Jogin I Glacier.

Auden’s Col trek begins from Gangotri and one can follow Auden’s Col and Khatling Glacier route to reach Kedarnath. The name of the Auden’s Col comes from J. B. Auden, who first crossed it for the first time in 1939-40.

The summit is at 5490m altitude and it connects the ridge coming from Gangotri III (6580m) peak on the north-west and the ridge coming from Jogin I (6465m) on the east and also binds a glacier coming from Jogin I on the north side of Rudugaira valley, and infamous Khatling glacier on the south side of Bhilangna valley.

One can read more about the 3-Pass Trek on the blog written by Neelima Vallangi. Anshul Chourasia and Sridevi Nair have also written a blog about Auden’s Col trek of June 2017 and Auden’s Col Trek expedition of 2018.

Rudraganga stream or Rudragairu (gairu means deep) or Rudugaira Gad (a small stream is English interpretation of Gad) drains Rudugaira glacier and eventually flows into the Bhagirathi river near Gangotri, and Bhilangna river originates from Khatling glacier and meets the Bhagirathi near Old Tehri in Garhwal region.

Auden’s Col Trek Permit

A permit is mandated by the local administration of Uttarkashi for all trek and adventure operators. Entry into Gangotri National Park is allowed only if one has a copy of the entry permit authorized by the office of the director of Gangotri National Park at Uttarkashi. Our Auden’s Col trek cost includes charges incurred to obtain the permits.

Auden’s Col Trek Route

First, we would take a side trip to visit Kedartal at a height of 4,780 meters. Then we would climb atop Patangani Dhar (4,900 meters) to get down into Rudragaira valley which provides access to Auden’s Col. Auden’s Col at 5490 meters above the sea level, is nestled between Gangotri and Jogin mountain ranges.

We can manage to cross Auden’s Col and Khatling glacier in a single stretch. Thereafter, we’ll descend to Chowki campsite the next day.

Amazing Khatling Glacier with Iconic Rabbit Ears!

Khatling  — one of the most notoriously difficult glaciers to negotiate in the western Himalayas of Uttarakhand.

The landform is strikingly similar to the Khumbu Icefalls of the Everest region.

Criterion For Auden’s Col & Mayali Pass Trek.

You must have done at least one high altitude trek before. Those who do not have the requisite trek experience of high altitude passes should not apply.

You must be physically fit to do the 12-day Himalayan trek. The trek leads you up to 18,000 feet high Col of Auden’s and through deep crevasses of Khatling glacier. At this altitude the air is thin and the rigors of the mountain can grind you down. You must give yourself enough time to prepare yourself for the trek.

NOTE: Trekkers are required to bring a medical certificate deeming them fit for high-altitude trekking at the start of the trek.

Backpack carrying: A porter will carry your backpack, please do not bring extra items but only the essentials needed for high altitude trek. Besides detailed planning, taking care of all the logistics, food, and good equipment, packing a backpack efficiently and carrying essential things play a key role in the success of an expedition.

FAQs About Auden’s Col & Mayali Pass trek





















No. We carry good quality 4 season sleeping bags(up to -10℃ comfort range), mattresses and pillows.


Generally, it is not required. The water from mountain streams is already purified and much better than the tap water you get in cities. You can carry a filter-fitted water bottle like Lifestraw Go Reusable Personal Filter Water Bottle.


Our trek leader is going to carry a first aid kit. We recommend that you bring a small personal kit of your own to deal with any bruises, scrapes or blisters that you may pick up along the way. The more difficult a trek is, the more exhaustive your personal first aid kit should be.


We have a camp crew who set up the tents and also take care of the cooking and clearing up the trash.


The key to preventing altitude sickness is to acclimatize properly. In high altitude areas, you should not gain more than 600-800 m of altitude. We advise you to take things easy and not to trek in a hurry.

Regular hydration of at least 5 liters of water a day is a must. Diamox (acetazolamide) is not recommended. Diamox simply tricks the body into breathing faster (by increasing the blood Ph slightly) and in fact avoids symptoms. Acclimatization is the only treatment for high altitude sickness. Take medication only if it is recommended by your doctor.


You need to carry the backpack/daypack. The daypack consists of essentials like water, a camera, snacks, and rain gear. The heavy luggage will get carried by a porter.

      Regards

  3. Hii..i am subham.I am interested about this trek.one of my dream trek..please send me details.thank you.

  4. If you are an extreme high altitude trekker and if Himalaya’s most adventurous, most secluded, less explored yet scenic routes fascinate you then trust me, Sonu Negi and his team are the best people for such extremely high altitude expeditions. His approach, meticulous plan, and execution are beyond excellence. I have done 3 passes expedition with him (Auden’s col being one of them) and I was awed with the kind of of efforts he and his team had behind the success of the same. I have seen few other trek operators canceling the expedition during the same time duration because of trail condition and excessive snow condition, but Sonu’s well-prepared team and his effort made this year’s first (and only) summit of Auden’s col. I would highly recommend him for his excellent service at high altitude, his mountaineering knowledge and his safety measurements.

  5. Hey!
    I would like to make some inquiries about the upcoming winter treks.
    I would be obliged if u could send me the itenary of the various treks and their respective costs.
    Thank you!
