Deciding On One of Nepal’s Incredible Trekking Options

When it comes to hiking and trekking, nothing comes close to Nepal! Age-old trails going up the various valleys of the Himalayas, the crossing of an occasional 5000-meter high pass, and the nearby presence of one or two of the fifty highest mountain peaks in the world – Nepal has it all.  Add to the mix a well-developed trekker infrastructure and deep-rooted cultural groups with their Hindu and Buddhist rituals and architecture, and you have the ingredients of an experience few, if any, other places can offer.

I was last in Nepal in 2006. Over a two-month period that autumn, I  walked the Annapurna Circuit trail and spent three weeks in the Everest region on the Three Passes trek, which to my mind, is the #1 long-distance trek in the world.  As 2016 approached, I was looking forward to a return visit and another great hike – but then the earthquakes of 2015 shook the country, so my plans were put on hold. Well, here we are three years later, and I am finally set to return.  I fly to Kathmandu via Abu Dhabi in early April.

The Annapurnas – From Tilicho Lake To The Nar-Phu Valleys

But where to go? I wanted to walk new trails and honed in on the two following possibilities, one in the Annapurna region and the other just east of it, with Manaslu, the world’s eighth-highest mountain, as the focal point.

Manaslu Trekking Guide coverThe plan was to organize it on my own using the itineraries of established trekking agencies as a guideline. (Click on the above links to see sample itineraries.)  I planned on hiring a porter to carry the bulk of my gear while I dealt with a daypack.  Both routes require special permits and a minimum of two trekkers accompanied by a guide.

I went so far as to get a copy of the Cicerone Trekking Guide to Manaslu and The Tsum Valley by Siân Pritchard-Jones and Bob Gibbons and spent some time reading relevant threads at the Trip Advisor’s Nepal forum. I even registered on the Trekking Partners website and posted a proposed itinerary and flexible dates. However,  November was probably much too early to be looking for a partner for an April or May trip!  There were only one or two responses from independent trekking guides looking for work!


Finding Info On a New Route – the Damadar Kund/Saribung La/Nar-Phu

Trekking Annapurna cover

Meanwhile, I chanced upon this  Cicerone guidebook titled Annapurna: 14 treks, including the Annapurna Circuit and Sanctuary (2017), also by Pritchard-Jones & Gibbons.  It included a write-up of a route I had never heard of before. Here is what I read –


See here for a copy of sections of the book in Google Books!

It was exactly what I was looking for!  Highlights include:

  • walking up the Kali Gandaki valley from Jomsom to the old capital at Tsarang
  • trekking across the wild high-altitude desert along the Hindu pilgrim’s trail to Damodar Kund
  • walking up the Khumjungar Glacier moraine to Saribung La and then coming down on the east side of the pass to the abandoned summer settlement of Nagoru
  • descending the entire Phu Valley from the glacier to where the Phu/Nar trail meets the Annapurna Trail at Koto
  • walking the first week of the Annapurna Circuit back to its start point (and this trek’s endpoint!) at Besi Sahar

Note: The write-up makes this point – “With a glacial zone en route, it’s probably only an option for those with some mountaineering background.”  This is not really the case.   While recognizing the need to be prepared for potential drama in the case of significant snowfall or blizzard-like conditions,  the reality will probably be much less daunting.  See this post for what was involved on our walk over the 6040m Saribung La pass –

Day 13 – Over Saribung La

Mustang-Saribung-Phu Trek Route

A trail much less travelled – but, as the write-up makes clear, also one I was not going to be doing on my own!  It would also involve tenting since there is no teahouse infrastructure along most of the route (i.e., from Yara to Meta).  Special permits to enter Mustang – an initial US$500. for ten days – would be required. Along with the tents, add to the list a three-week supply of food and basic mountaineering equipment to deal with the glacier traverse.

Finding An Agency To Organize The Trek:

More googling led me to this trek organized by the respected Australian adventure travel agency World Expeditions.  I gulped when I saw the price – $5395. CDN!  Ouch! However, two internal flights are included ($250. U.S.), as are the $650. U.S. for the Mustang entry permit and another $200.+ for the three nights at the five-star Kathmandu Radisson.  Also included are a down sleeping bag, a down jacket, and an insulated mat.  I went over their itinerary and other info.  All in all, it looked pretty good!

I put the WE offer to the side while I looked for other trekking agencies that had something similar.  I found trips organized by two U.K. agencies.  KE Adventure Travel, the first one, has one called Saribung Peak and the Damodar Himal Reconnaissance. It includes a walk up the 30º snow slope from Saribung La up to the peak.   Jagged Globe has a trip with the less pretentious title Saribung Peak and Upper Mustang.

In both cases, the trip cost was higher than the World Expeditions offer, due in part to the Saribung Peak climbing fee.  They both also include a day or more in Lo Manthang, something not included in the World Expeditions itinerary.  The WE route only goes as far as Tsarang before turning east to Luri Gompa and Damodar Kund, which I did think was unfortunate.  To be so close to Lo Manthang and yet not visit?

I also checked out some Lonely Planet and Rough Guide-recommended Nepali trekking agencies based in Kathmandu, but not much was coming up and, in all cases, I was the only client and I was the one responsible for getting other people to join to make the trip possible!  To enter Mustang, you need a trekking agency, a minimum of two trekkers, and a guide. A porter is optional.

A few days later, I visited the World Expeditions site again. The price had dropped to Cdn $4950.!  It was late November – perhaps it was a Black Friday sale?  I made a phone call to their Ottawa office to see how many had already signed up.  The answer: four.  Still not sure “Go” (six is the official minimum) but probably a “Go” if I signed up.

I decided that the premium I was undoubtedly paying by choosing a non-Nepali agency was justifiable for the peace of mind it offered.  Here is what World Expeditions does:

  • It uploads a flashy web page to attract my attention!
  • It attracts the clients that make the trip possible,
  • negotiates (as required by Nepali law) with a Nepali trekking agency to do the actual trek, and
  • provides a comprehensive information package on pre-trip planning and requirements.
  • Its use of the same agency over the years indicates that certain safety, food, and all-around competence standards are presumably being met and reinforced with training sessions for the guides.

Update March 2023: I did this trek in 2017. World Expeditions no longer offer this trek! See here for what Nepal tours/treks they do have available.


Highland Expeditions – and Highland Excursion(s)!

Arranging your trekking agency before you leave home is better -even if a bit more expensive – than showing up in Kathmandu and spending the first few days trying to make it all happen on my own – and wondering if the agency I had chosen was up to the job.

I would later ask which Nepali agency was in charge of the actual trek.  I understood that the local agency that WE dealt with was Highland Expeditions.

Click on the header below to access their website –

The trekking crew’s experience in handling high-altitude expeditions, up to and including summits of Mount Everest, was reassuring.  While the Mustang – Saribung Traverse is hardly in that elevation class, it still involves crossing the 6040-meter pass at Saribung La after a couple of nights of tenting at 5000 + meters.  Knowing that the crew has been there before is comforting!

Update- late February!  Oops!  I got the name of the agency wrong!  It is Highland Excursion(s), not Highland Expeditions, which will be handling the trek!  That feeling of reassurance I mentioned above?  I am not feeling it quite so strongly now!

If you were to judge the two agencies solely by their websites, then Highland Excursions is clearly not in the same league as Highland Expeditions.  Arranging pilgrimages via plane and jeep connections to Muktinath and Mount Kailash seems to be its primary focus.  Its Nepal Trekking folder is very thin on actual high-altitude camping treks.

The sub-header on the home page –  One of the leading adventure travel company – has a glaring grammatical error. It could use the qualifier Nepal’s as in “One of Nepal’s leading adventure companies” to make it slightly more plausible.  As I scroll down the page,  seeing the heading “Popular Destination For 2014”  in 2018 does not show great attention to detail!

Now I hope that World Expeditions knows something this website is not conveying!  A website is one thing; the trekking agency crew of guides, sirdar, cooks, and porters on the ground is another.  Reviews of this and other WE trips in Nepal are overwhelmingly positive.  As always, time will tell. Stay tuned for the trip report!

Update: The on-the-ground crew –  20- all from the Tamang community except for the lead guide and overall leader with a Rai cultural background.  100% competent and always ready to make things easier for you.  Ten porters, a cook team, a couple of sherpas, a sirdar…at times, as an independent do-and-carry-it-yourself camper at heart –  I was embarrassed that so many people were looking after me.  One negative was that only one of them – the guide and overall leader – spoke English. He was often at the very end of the long string of crew and trekkers on the trail.   

Our trek begins in Jomsom, the administrative capital of Mustang, at 2720 meters.  On Day 1, we meet the trekking crew and walk up to Kagbeni along the Kali Gandaki River, which we will ascend all the way to Tsarang over a four-day period.  Then it is east across what is a high-altitude desert towards Damodar Kund.  We have twelve days to acclimatize as we walk up the Khumjungar Glacier on our approach to the trek’s high point at Saribung La.

Wikiloc GPS Track of the Trek:

The route can be seen in this Wikiloc upload from November 2016 upload by Aymami. The only difference will be that ours does not include a visit up to Lo Manthang, some 13 kilometers north of Charang.  Just click on the image to access the GPS track.

Instead of the walk up to Lo Manthang, our itinerary has a rest day in Charang scheduled for that day.  From Charang (also spelled Tsarang), we head east across the Kali Gandaki towards Yara and to Damodar Kund following the Hindu pilgrims’ trail.


Acclimatization: A Key Consideration

While acclimatization problems have not impacted any of my mountain trips so far, it is a potential issue that I am always aware of.  The ascent schedule arrived at by the trekking agency, which says it has done this trek before without any problems, is a “plus.”  As a point of comparison, Kilimanjaro is 5895m, and many agencies offer six or seven-day treks up the summit and back down.  Little wonder that many do not make it or feel pretty lousy when they do.  Our trek schedule provides much more time to acclimatize.

Upper Mustang-Saribung La-Phu Traverse – campsites and altitude

Update: I created the above graph using elevations from the World Expeditions trip notes. A number of those figures are incorrect.  See the posts for each day for the actual campsite elevations!

To ease my adaptation to the thinner air, I also had my travel clinic doctor write me a prescription for acetazolamide (known by the brand name Diamox); it speeds up the acclimatization process.  It does not mean you can ignore the usual acclimatization protocol!

Update: Four of five of the trekkers made use of the Diamox as a prophylactic.  I took a 250 mg tablet each day (half upon getting up and the other half at supper ) from Pokhara to the day we crossed Saribung La. There were no side effects other than the copious peeing.  That pee bottle for in-tent use at 3 a.m. was an essential piece of kit!  

Googling the topic will turn up numerous pages; this brief post – How To Prevent Altitude Sickness For Trekkers – summarizes things nicely.  However, the “drink five liters” command is a bit much! Given the soup, oatmeal, and other food containing water, you may end up causing another condition – hyponatremia –  if you overdo the water.  Clear urine is said to be a good indicator that you are properly hydrated. [Or maybe not! See this opinion piece – Should you pee clear? –  for a different view.]

Other Major Considerations:

Other than acclimatization, other considerations revolve around

  • fitness level
  • possible stomach problems
  • gear
  • learning more about Upper Mustang and Damodar


Upping My Fitness Level:

It is mid-February as I write this; I have been following a high-altitude trekking program developed by Scott Johnston and Steve House since early December.  It is a six-day-a-week training plan made up of two strength training sessions and four cardio sessions.  I found it on their Uphill Athlete website. (See here for plan details at the Training Peaks site.)

I have another seven weeks to go before departure.  Since I get to Week 12 of the plan in mid-March,  I’ll just repeat and gradually increase the workload of the program’s last week when I get there.    Of the 60 sessions so far, I have missed two.  I hope to keep up that commitment level until the last day of training –  April 8!

Update: The Uphill Athlete program has changed how I prepare for mountain trips. Too bad it happened when I was 66 instead of 46!  For my next trek – maybe the Snowman in Bhutan – I will repeat the 16-week plan I followed for this trip. 


Dealing With Stomach Problems:

On my last mountain trip in September of 2014 – a two-week trek down Bolivia’s Cordillera Real – I got food poisoning the day before the trek began!  This time I will absolutely avoid the obvious things you should avoid  – including the green leaf salad I had at that La Paz restaurant!

This time I will take a treatment of  Dukoral; it is a non-prescription oral vaccine that helps prevent diarrhea caused by E.coli.  Some hand sanitizer and my Steripen – a device that purifies water by emitting UV rays –  will also come along to eliminate other possible dangers.  Since all the food will be prepared by the cook crew,  I will assume that they’ve got it all figured out!  So too with the daily three liters of water that we will be consuming to stay hydrated.

Also in my meds jar are a half-dozen or so of each of the following –

  • loperamide hydrochloride (a generic version of  Imodium)
  • rehydration packets
  • Azithromycin in case of severe diarrhea.

I hope I don’t have to use them!

Update: Acclimatization was not an issue though I did experience a bit of puffiness under my left eye. No gastrointestinal issues at all!  Maybe it was the Dukoral? Top marks to the cook crew for their obsession with keeping things clean!


The Right Clothing And Gear:

The last consideration is the gear. Having been on enough of these mountain trips and being a bit gear-obsessed, I have amassed more clothing and other gear than I need!  My -15ºC Western Mountaineering sleeping bag will come along.  I just need to give it a wash before I go; it has been on a few canoe trips since it last was cleaned.

Also coming along is the WM Hot Sac VBL, a vapour barrier liner that helps prevent the down from getting wet from body vapour in sub-zero temperatures.  As we go up beyond 4500 meters, overnight temperatures will be in the -10ºC range.  A frozen water – or pee – bottle in the morning will be a sure thing!

Update: In the end, I left my sleeping bag and vapour barrier at home.  I made use of the “free” sleeping bag provided by the trekking agency.  It was fine, even if twice as bulky as my WM bag.  Also provided was a fleece sleeping bag liner but I left it behind in Kathmandu and wore my Arcteryx Rho Polartec top and bottom in the bag instead.

Getting To Kathmandu: 

In October of 2006, I flew Air Canada from Toronto to Delhi via Zürich. After overnighting in a downtown Delhi hotel, I returned to the airport for the flight to Kathmandu.  On my doctor’s recommendation, I also took malaria medication (a week’s treatment!) as a precaution for my twelve hours in Delhi!  That experience left me determined never again to subject myself to a half-day of Delhi’s airport and roads pandemonium.

Instead, I fly from Toronto to Abu Dhabi and then, after a three-hour wait, get on the flight to Kathmandu.  Total travel time from YYZ to KTM – 19 hours, almost half the time I was in transit in 2006.  Of course, time will tell if this year’s itinerary actually unfolds without any bumps!

Update: I would definitely fly Etihad again! It made getting to Kathmandu a breeze. All four flights – two there and two back – were on time, food, even my vegan option, was okay for airline food, and while the economy seats were a bit cramped, they are on any airline!  Abu Dhabi is a nicer airport to spend time in than New Delhi’s Gandhi. And I was spared the overnight in Delhi. 


Learning More About Mustang/Damodar Kund

Other than obsessing about gear, the other thing I overdo is finding out as much as possible beforehand about the place I am going to.  Geology, environment, history, anthropology, religion, politics – it may be the school teacher in me that turns entering Mustang to entering a classroom!

Since I signed up for the trek I have also learned that one of our tent spots is by Damodar Kund (kund is a small lake or pond); it is a Hindu pilgrimage site associated with the god Vishnu (aka Narayan).

Reading up on the Phu Valley has made clear that I am entering a very special and isolated nook of the Tibetan Buddhist world.  Going with some basic knowledge will mean that the questions I ask are not obvious to which I can find the answers in a Wikipedia article!

Himalaya_filmEverest 2015Nothing like a 90-minute Stair Master session at the gym to create some spare time to view videos!  Already done is the six-hour Michael Palin BBC series on the Himalayas. I have also watched the 2015 movie Everest,  a retelling of the May 1996 climbing season events described in Jon Krakauer’s classic Into Thin Air.


Also watched was Eric Valli’s Himalaya from 2000, which was filmed in the upper Dolpo region to the west of Mustang. Not specific to Mustang, but still a great way to forget that I am walking on a treadmill set at the maximum incline with a 12-kilogram pack on my back for almost two hours is the Joe Simpson epic Touching The Void.

Here are a few more of the videos I have looked at over the past few weeks to get a grip on various aspects of Mustang (pronounced Moose dung!). They all really bring home how little I know about this corner of our world – and how lucky I am to be able to spend some time there this April!

Stay tuned for a recap of my trek when I get back in May.  Until then, it is back to my training and continuing education program.  Not even mentioned in all of this is that I get to spend five days – three before the trek and two after – in the most fascinating city I have ever visited – Kathmandu!  I will visit the half-dozen UNESCO World Heritage sites in the valley and see how they fared in the 2015 earthquakes.

Below is a photo (the labelling is mine!) of the approach to Saribung La, the literal high point of the trek! Check out Paul Boslooper‘s image collection for an excellent visual summary!

Who needs to go anywhere anymore – it is already all online!
