This trek has superb views of Mt. Chomolhari and Mt. Jitchu Drake and includes crossing of high passes of Nyile La (4,890m) and Yale La (4,930m).

Mount Chomolhari at 7,134m is the second highest peak in Bhutan lying on the northern border with Tibet. The trek to Chomolhari Base Camp traverses beautiful and varied country and after a day acclimatising and exploring around Base Camp we cross a high mountain pass to reach the Camp below Lingshi Dzong. This is a monastery and fortress built by the first ruler of Bhutan to defend against a Tibet invasion, the Dzong has a superb location on a hill overlooking Lingshi village.

From Lingshi the route crosses another Himalayan pass as we start the trek south back to Bhutan's capital, Thimphu. At this pass we are rewarded with stunning views of Jitchu Drake (6,900m) and Chomolhari as well as many un-named and un-mapped peaks along the Bhutan - Tibet border.

At the start of the trip we organise a visit to Haa valley for two nights in order to help essential acclimatisation before the trek. This valley offers wonderful scenic walk along trails passing through traditional villages and magnificent monasteries. This is a beautiful area adorned with pristine alpine forests and still remains one of the least visited areas in the country.

  • We are Himalayan trekking specialists and we have been operating trips in Bhutan for many years. Roland Hunter, owner and founder of The Mountain Company, has modified this itinerary based on his first-hand experience of Chomolhari Base Camp.
  • Our approach to organising trips in the Himalayas has helped The Mountain Company win awards such as 2018 Gold Award as AITO Tour Operator of the Year and 2015 Bronze Award as AITO Tour Operator of the Year. Read more about our Testimonials and Awards
  • Our Chomolhari Base Camp itinerary has been designed based on first-hand experience which is the best in terms of acclimatisation, safety and enjoyment. Unlike most other itineraries we now include one night in Paro and two nights in Haa Valley before starting the trek for essential acclimatisation.
  • We have chosen the optimal times of year to complete this trek in Spring and Autumn seasons. If one starts later in Autumn/ Fall or earlier in Spring season there is a high chance of the passes into will be blocked by winter snows.
  • The Mountain Company will receive bespoke weather forecasts from and from our in house forecasting throughout the duration of this trek.

The route climbs to Barshong where there is a ruined dzong and a few other buildings.  It is possible to camp here though it is not ideal due to the site being in a swampy meadow, most groups prefer to continue to a camp another 1 ½ hours further along the river.

The trail stays on the left hand side of the river and climbs over ridges and side valleys.  After a steeper climb followed by a path through rhododendron forests the trail descends to Dolamkoincho, the camp in a meadow at 3320m.

Practical Information

A Typical Day On Camping Trek

The day starts with an early morning mug of tea brought to your tent by one of the assistant guides. Before heading over to the mess tent for breakfast you will pack your overnight gear into your duffel bag. During breakfast the tents will be packed away and, after the porters have arranged their loads, they will set off on the trail in the cool of the morning. After breakfast, probably between 7am and 8am, we start walking. The pace of the trek is leisurely with plenty of time to enjoy the scenery, take photos and explore the local villages. Lunch will be around 11am at a spot by the side of the trail and is prepared for us by the cooks.

There is more walking after lunch and normally you will get into camp by mid afternoon with the tents already put up by the local staff. In the evening a three course meal is served in the mess tent around 6-7pm. After supper the international leader will discuss the plan for the next day with the group. People might stay in the mess tent chatting about the day’s events for a while before retiring to their tent for the night.

While on the trek, the cook will provide good quality food in sufficient quantities.  For breakfast you are likely to get porridge or cereal, toast or chapatis, omelettes and a range of hot drinks. For our camping treks we provide fresh coffee from our Bialetti Moka coffee machine. On arrival to camp in the afternoon you will be given tea and biscuits and a three course meal will follow later in the evening.


We bring a Thuraya satellite phone for logistical, safety and personal use. Personal calls charged at £4 (US$5 or €4.50) per minute and £2 (US$3 €4.50) to send and receive SMS text.

It is worth pointing out all of our trips have a certain degree of risk, this is of course part of the attraction of adventure travel and why so many people choose to join this type of holiday.
