The Day’s Basic Data and Map
- Calendar date: October 1, 2019
- Time: 3 hrs.
- Distance: about 6.5 km.
- Google Earth 3D satellite view: click here for an interactive view
- Start point altitude: Jomolhari B.C. 4044m
- High point altitude: Tsho Phu lakes at 4350m
- I used a Sony RX100 III to capture most of the images you’ll see below; a fellow trekker’s Huawei P30 captured the others. (Thanks again, O, for letting me use them!)

The Acclimatization Issue:
The ascent up to Jomolhari Base Camp from Paro is almost 2000 meters over three days. Those starting the Snowman Trek will hopefully spend a day before the trek acclimatizing with a walk up to the Taktsang Gompa. Still, a 1100-meter gain from Shana to Jomolhari in three days is pushing the recommended limit of 300 maximum per day. If trekkers are going to experience altitude sickness, it will likely occur within the first few days. All trekking itineraries include a rest/acclimatization day at the Jomolhari campground to provide some extra time for bodies to adapt to the thinning air.
As the above chart suggests, hikers feeling okay at Jomolhari should remain comfortable through Laya, as the altitude of each subsequent campsite stays consistent at approximately 4000 meters. The four high passes of the trek after Jomolhari provide excellent additional acclimatization and illustrate the mountaineer’s motto – “Walk high, sleep low”.

Snowman Trek effective-amount-of-oxygen
There were sixteen trekkers on this trip. Only three of us – I was one – used Diamox, a drug that helps the body adapt. I had been encouraged by the guide to forget about the Diamox. Of the 13 who did not use it, most seemed to do fine, though one did drop out at Laya because of respiration issues and the other three days before the trek ended for undisclosed reasons.
I used it since I had done so on a half-dozen previous high-altitude treks and had no issues at all – not even a headache. While some may argue that I was a victim of magical thinking, the evidence supports its use as a preventive measure. Obviously, it does not exempt trekkers from other in-trek protocols:
- a moderate rate of ascent
- adequate hydration
- abstaining from alcohol

Scarce Mountain Views!
An early morning (5:45!) call by the guys in the kitchen, and those who got up were rewarded with a clear view of a mountain peak in Bhutan – our first since our arrival four days before! In front of us was Jomolhari (7315m), the highest peak on Bhutan’s western border with Tibet. The image below has the peak on the left; the one in the middle is Jomolhari II at 6935; the sharp peak on the right is the 6850m, Jitchu Drake.
I took a couple of shots and crawled back into the tent for another hour of rest. Given that it was a rest/acclimatization day, we would start a bit later.

Acclimatization Hike To Tsho Phu:
The day’s major planned activity was an acclimatization hike with 310 meters of elevation gain, most of which happened in the first hour. We were going to hike up to the Tsho Phu lakes on the other side of the river. A clear day and the extra elevation would mean we would get to look back at some nice views of what you see in the satellite image below.
However, it was not meant to be! By the time we left at 9:00 a.m., the clouds had rolled in and that blue sky that we had seen at 5:45 was pretty much gone for most of the day. The shot below shows the view from the other side of the river halfway up our climb to the plateau and the lakes.
As we walked up the hidden valley, we saw some Himalayan blue sheep on the slopes. They were far enough away that even with the 720mm reach of my Sony HX80, they were barely discernible!
The shallow lakes we were walking to are said to be full of brown trout but as you approach a sign informs you that no fishing is allowed. Also discouraged are bathing in the lake and spitting into it!
We passed by a yak herder’s temporary tarp shelter just before the first lake and heard the barking of a Tibetan mastiff guard dog. Luckily, he was chained to a post since the guidebooks caution trekkers about the unfriendly nature of the dogs if they happen to be off-leash!
Shortly after we came to the area between the two lakes, it started to rain lightly.
We did see a few yaks grazing on the hillside above the Tsho Phu but the guides noted that there would have been more up here for springtime. We had an unexpected cup of tea courtesy of Karma and Kinley, the guys who took care of lunch service during the trek.
While we stood there and sipped on our tea, our guide Tendin described another popular trekking route – the Jomolhari Loop Trek – that comes up to the Tsho Phu lakes before heading back in the direction of Shana. See below for a description of this shorter trekking route!

A Shorter Jomolhari Trekking Route Option
Not everyone wants (or has the time or money) to sign up for the 23-day + Snowman trek. The trail from Shana to Jomolhari is undoubtedly the one most walked by trekkers visiting Bhutan. This probably explains why it certainly had the most litter of any section of the Snowman Trek trail.
The most common one-to-two-week Jomolhari options include the following:
- Shana-Jomolhari-Laya-Gasa…at 12 days, the most ambitious of the shorter trek options. Coming down from Laya, the exit is Gasa. However, a rough road now comes within four hours of Laya.
- Shana-Jomolhari-Nyile La-Lingshi- Shodu-Barshong-Dolam Kencho-Dodena (Note: road construction will soon mean a road all the way from Lingshi to Dodena!)
- Shana-Jomolhari-Tsho Phu- Bonte La-Soi Yaktsey-Gunitsawa near Shana
The sketch map below illustrates #2 (The Jomolhari Loop Trek). It is Trek 4 in the Bart Jordans guidebook and has the name Jomolhari Bonte La Circuit. It uses the trail we had taken up to the Tsho Phu lakes and then continues on to the high pass of the trek at Bonte La (transliterated as Bongetela on the map below) and then returns to Gunitsawa near Shana via the Soi Yaksey valley.

Back To the Jomolhari Campground
And then it was back down to our campsite.
Waiting at the campsite would be a lunch table set up outdoors. The weather cooperated long enough for lunch, and then – in mid-afternoon – it started to rain again. Some retired to their tents; others moved into the guesthouse dining area. For a brief period, the clouds cleared, and we saw some blue sky as we looked toward Jomolhari.
I turned to the east and looked back at the eastern slope of the Paro Chhu that we had climbed in the morning on our way to the Tsho Phu lakes. With our acclimatization mission accomplished, the next day we would be moving on to Lingshi, crossing our first high pass of the trek.
