Auden’s Col & Mayali Pass Trek | Across Khatling Glacier

Auden’s Col & Mayali Pass Trek | Across Khatling Glacier

Auden’s Col is a pass that connects Rudugaira Valley (Gangotri) to the Bhilangna Valley (Kedarnath). Our 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 Col is about 5400 meters high. It connects two glaciers: the Khatling Glacier and the Jogin-I glacier.

Auden’s Col trek begins from Gangotri. From there, one can follow the Auden’s Col and Khatling Glacier route to reach Kedarnath. The name of the Auden’s Col comes from J. B. Auden (brother of Anglo-American poet W.H. Auden), who first crossed it in 1939-40.

Auden’s Col: The 3 Pass Trek Expedition In Uttarakhand

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.

You 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.

From Chowki we would take a left turn upwards and reach Mayali Pass (5,050 meters) in the next two days, and then camp next to Vasuki Tal. From there we would descend to the Kedarnath shrine and get back into civilization.

What is Col?

The word ‘Col’ is a geographical term for a saddle-like depression in a ridge between two peaks.

Mountain Col

Auden’s Col lies between Gangotri III (6537 m) & Jogin I (6465 m) and the crossing is one of the finest high altitude treks in the Indian Himalayas.

Ice falls of Khatling glacier
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.

Condition 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.

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

Important Documents

  • Photo-ID( Passport/Driving License/Voter ID/Aadhar).
  • Fitness certificate.
  • Trekking Permit

Many people assume that they need to have athletic strength to complete a trek like Auden’s Col, which is not completely true. The athletic strength is needed but mental strength matters equally. Anyone with average physical strength and strong mental strength can negotiate the long stretches of Auden’s Col/Khatling glacier and complete the Auden’s Col trek. 

To boost the physical strength, cardio (aerobic) exercises, including hiking, cycling, swimming, can help you gain fitness before the start of your trek. One important thing to consider is that the treks are not a race, so you need to maintain a gentle pace with sufficient breaks and acclimatization.

The best time for trekking Auden’s Col trek is from May(from 4th week) to September(barring monsoon period). During the spring season(in May & June month), wildflowers, including pink rhododendrons, Bhrama Kamal bloom in Gangotri valley in Uttarakhand. The clear skies and stable weather is the major attraction of the trek.

The autumn month of September is famous for its soothing climate and favorable temperatures. The Autumn month is good for the night or dawn/dusk photography. The monsoon and the winters are generally avoided because of the risks and the challenges posed by the Gangotri group of mountains.

During the trek, numerous mountain streams originating from Gangotri glaciers(like Kedar Ganga, Bhilangana, and Vasuki Ganga etc.)  are the main source of drinking water and water for cooking. Mountain stream water & snowmelt water is perfectly safe to drink though the problem of silt mixed water may arise during the rainy days. We filter water through a sedimentation process. We also recommend trekkers to carry a water bottle fitted with a filter. You can get filter-fitted bottles easily in the market.

While trekking it is extremely important to stay hydrated. During the trekking on sunny days, you will be thirsty more often. You can add hydration salts or glucose to the drinking water that keeps you healthy while improving the taste of the water. 

The trekking hours are not fixed. The prevailing weather conditions, terrain and walking pace will determine the daily trekking hours. In general, we plan the trek for five to six hours of daily walking on average. In a group trekking expedition, it is essential for us to gauge every individual’s stamina level and plan our journey ahead accordingly.  Starting the trek early is key to avoiding the midday heat and arriving at your destination early. This leaves with enough time to rest, acclimatize, and explore the Gangotri Nationa Park region.

There will be toilet tents. Our crew will dig a hole in the ground then erect a toilet tent around it for privacy. We brief our guides to locate the toilet tent away from water sources and on departure the next morning the hole will be filled and covered with earth. We recommend you always keep a roll of toilet paper & a hand sanitizer in your day pack.

The rule of thumb is to use several thin layers rather than just one or two thick layers. This allows you to peel layers off or put them on depending on the weather and the time of day. For your base-layer choose a fabric that soaks moisture away from your skin and dries quickly. Your outer layer should be fully wind and rainproof. We recommend you carry good quality thermals, woolen socks & a waterproof jacket. A windproof outer layer is essential to combat wind-chill(essential for altitudes like Auden’s and Mayali). Choose a thermal base-layer and fabrics that wick sweat away from your skin to avoid getting wet and cold. You need to protect your hands and feet with high-quality thermal gloves and socks, also a hat to protect your head and a balaclava to protect your face. 

If you have no prior experience of walking long stretches on glaciers, you should bring crampons. Crampons fitted trekking boots help you get past the snow with ease. Many people prefer walking on the glaciers without crampons. Auden’s Col trek route has a long glacier stretch that is riddled with crevasses and moraines. We recommend crampons for such terrain.

You need good quality Gore-Tex boots with decent grip and secure ankle support. Your boots must be fully waterproof and at higher altitudes(like Auden’s Col basecamp & Khatling glacier snowfields) we recommend boots with trekking gaiters for crossing Auden’s Col snowfields.

This is very much personal preference. Some people swear by them, especially on treks with long and steep ascents and descents(like the ascent to Patangini Dhar, descent from Auden’s Col and Mayali pass), others find they get in the way and prefer to manage without. If you have weak hips, knees or ankles they are an effective way to reduce the strain.

There’s no other way to prepare for altitude than to acclimatize slowly. Our trek itineraries have been carefully planned to allow for gradual acclimatization (at Bhoj Kharak and Kedar Kharak). Altitude sickness can affect the fittest trekkers just as easily as the less fit. Once on the trek, the main recommendation is to keep your fluid intake up and stay hydrated. We don’t recommend Diamox(acetazolamide). Diamox actually tricks your body into breathing faster (by changing the Ph of your blood slightly) so it actually prevents the symptoms. The best cure for high altitude sickness is acclimatization.

During the trek, your luggage is carried & transported by porter & mules so all you need to carry is what you need during the day, for example water bottle, camera, extra clothing, sun-cream, and a small personal first aid kit. We recommend a 15 to 25-liter day pack for Auden’s Col trek

The best way to train for the Auden’s Col trek is to spend plenty of time beforehand simply walking & jogging. Aerobic training at the gym helps too, but there’s no substitute for simply walking & trotting for several hours at a stretch. It’s also a good opportunity to check out all your trekking equipment, clothing, and footwear – to make sure it’s all comfortable and works OK.

It really isn’t a problem. You can walk at your own pace nearly all the time, as we have enough guides to escort walkers of all speeds. Occasionally for safety reasons the trek leader might pull the group together (eg. in bad weather or on a tricky section of the trek route like ascending and descending Auden’s Col, Crossing crevasses over Khatling glacier, Crossing the makeshift bridge over Bhilangana river,  and climbing up to the Mayali pas. In general, the group can string out and everyone finds their own comfortable walking pace.

Assessing your personal fitness is quite subjective. Your fitness level is often pitted against the level of difficulty of a trek route that includes various factors like the number of hours of walking each day, the total number of days, how long and how difficult is the ascent of descent stretch, terrain, altitude, and likely weather conditions. Auden’s Col conflated with Mayali pass is a 12/13-day trek riddled with long glacier stretches, crevasses, rock falling zones, and moraines.  To match the difficulty level of Auden’s Col trek you need to have previous high altitude trekking experience. One cannot climb a pass or peak without being physically and mentally fit.

The route traverses through the valley of Rudugaira to Auden’s Col and ends at the village of Ghuttu, and for the 3-pass expedition, It’ll be conflated with the Mayali Pass to go all the way to Kedarnath. It is also possible to cross only Auden’s Col by starting the trek at Gangotri and exiting at Guttu(i.e. Mayali pass would be skipped). Another trail in the valley between the valleys of Gangotri and Rudugaira will lead us to Kedar Tal. Kedar Tal offers magnificent views of the Thalay Sagar and Bhrigupanth peaks. In the first part, the route would take us to Kedar Tal, and then we cross over from Kedar Ganga (Kedar Ganga is a tributary of the Bhagirathi River) to Rudugaira Valley through a pass called Patangini Dhar. In the second part, we will cross Auden’s Col and trek over Khatling glacier to the origin of the Bhilangna river. In the last part, we will switch over to the Mayali Pass trail to reach Kedarnath.

Bhoj Kharak, Kedar Kharak, and trail to Kedar Tal. The trail is steep uphill including numerous switchbacks through the birch forest. The birch trees are referred to as Bhoj trees in the local dialect and so the first campsite inside the Bhoj forest is named Bhoj Kharak.

Gangotri has many small hotels and lodges. You can stay at Harsil also. Harsil is an hour’s drive from Gangotri.

Any trek is doable without a guide:

  • If you know the route(or you know how to read maps and use GPS) 
  • You have complete climbing and camping gear.
  • You have extensive experience of trekking in the Himalayas. 

Even if you meet the above conditions there are still certain caveats that make a trek like Auden’s Col treacherously dicey.

  1. I will do this trek in July..can you provide the details for this trek..itinerary + cost + when are you organising this trek ?

  2. Hi,
    Can cost be emailed to me. Am planning this in month of sept or whatever dates suitable post monsoon.

  3. Hii..i am subham.I am interested about this 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.
