trek overview

Often known as the valley of Gods, Har ki dun is the journey to a mystical civilization deep inside the Govind Panshu National Park. This valley lies in the outskirts of Uttarakhand state and shares a border with baspa valley of Kinnaur District, Himachal.

Har ki Dun is a quite popular attraction among most of the trekking community. The valley was known to the outside world when a Britisher named Jack Gibson, who was a Teacher in Doon School explored this place and shared his experience to the other adventurers of his community. Lesser the world knows that one of the first mountaineer to ascend the world’s highest peak Mount Everest, Tenzing Norgay has climbed Bandarpunch in this region as being a part of the Jack Gibson Team. Jack Gibson were very fond of this valley, a memorable span of his life was spent here to enrich the local culture and educate young people about mountaineering. The trek present beautiful landscape of thousand year old villages, rumbling waterfalls, proximate view of snow capped himlayan peaks and diversity of prosperous flora and fauna in the valley. We cross a thousand years old villages like gangad and osla which are still out of connection from the outer world. Osla is the last village and a key attraction for most of the trekkers in the valley, due to its scenic loaction. Every village in the Valley has a wooden temple which is dedicated to lord someshwara. Locals have a strong belief in Lord Someshwara. Many myths state that lord someshwara temple is of Duryodhana and many others believe that it is devoted to lord shiva. Some of the prominent Himalayan peaks like Black peak, Bandarpoonch, Har ki Dun peak, Swargarohini and Hata peak can be glimpsed from this trek.

We Pick up all the participants from Dehradun Railway Station around 6:00 am. After a short briefing, the scenic drive to Sankri begins. This amazing road trip slowly changes from straight City Roads to zigzag bends of Mussoroie Mussorie – “Queen of the Hills” is a quaint hill station, situtated 32km away from Dehradun City. As soon as we are about to reach mussorie , you will witness a beautiful view of Doon Valley. The astonishing beauty of the small city surrounded by dense Forest and lower Himlayan range is hard to describe in words.

We cross popular hill towns like Nainbagh, Damta, Naugaon, Purola (kamal Ganga flows alongside the route), Mori, Natwar( Confluence of Rupin supin ) on our way to Sankri. After Purola the drive to Sankri passes through a beautiful stretch of Pine forests.

Finally, after the long drive of 9 hours we reach Sankri by evening. Nestled at an elevation of 6400 ft, Sankri is a quaint village as well as a small market with couple of shops around. Most of the shops retails with Warm clothes, Trek Essentials and rental gears. Sankri is the base camp of many popular as well as unexplored treks in Govind Pashu Wildlife Sanctuary.

Day 2: Sankri to Chilurgad
  • Drive: 1 Hour, Trek: 5-6 Hours


Post Breakfast, we start today’s journey. We board a local vehicle from sankri to reach Taluka, the starting point of Har ki Dun Trek. After a crazy one hour ride through the curvy and bumpy roads, the vehicle drops us near the Taluka village.

Taluka is a small village with a few shops and Government guest houses. The trek begins from here starting from a narrow rocky path. The fragrance of cedar trees can be felt around Taluka. The trek begins from a well marked trail along the supin river on our left. The intense tone and gushing rapids of the river makes our journey more fascinating.

During summer season, one can spot huge farmlands covered up with Chaulai, a local crop. The treks stretch with little ascends and descends making the trail an easy as well as a bonus for today. After walking for a distance, we spot a tiny settlement on the ridge, known as Datmer village. Several paths can be discovered to reach Datmer village. A beautiful sculptured wooden bridge can be seen which passes to the forest, This bridge is identified as Baranti pull often crossed by locals to collect wood stock. Trees like walnut, maple, and oak are most common on this trail. One can find walnut lying on the trail during autumn season .

As soon as we will reach Chilurgad, tents can be seen pitched at a distance. The camping site offers a graceful view of little streams that merges into the supin river. Enjoy the chilly evening with sips of tea and a view of Grand peaks covered with snow.

Day 3: Chilurgad to Seematra
  •  Trek: 4-5 Hours


Osla village can be seen from chilurgad campsite cradled on the cliff, across the growling supin river. From Chilurgard the route to reach osla village is linked by a neat wooden bridge. Osla is the last village on the route to har ki dun and a key attraction for every explorer visiting this valley. The landscape of the alluring village is surrounded by snow-capped peaks and terraced farms. Each season delivers varied complexions about the elegance of the habitat. During the late monsoon, the area blooms up with a local crop known as Chaulai. This red crop turns pink with period and adds a magnificent color around the territory. As you move further and walk out of the village territory, you can spot a magnificent waterfall at a distance. The splendid view of the waterfall is a perfect delight to look at. Moving ahead on the trail, a small temple devoted to Kanda Rani can be glimpsed. The climb turns up to a steep slope after we cross the last tea point. Soon we reach a huge camping ground, Kalkatudhar which was earlier used by the locals as farmland, the tree line cannot be noticed at this part of the wide meadow. Kalkatidhar is a large pastureland which offers an eye-catching view during different seasons. This passage of the trek is steep and fatiguing, so it takes a little while to complete. The Himalayan ranges like Bndarpoonch and Black peak are visible from this part of trek. Leaving the meadows behind as we move forward through the narrow trail, After a half hour journey , we finally reach seematra. This camping site is a small clearing area covered up by treeline all around. Overnight stay will be in tents.

Day 4: Seematra to Har ki dun and back to Seematra
  •  Trek: 5-6 Hours


The trail to reach Har ki doon from seematra is easiest, if compared to other days of the trek. Another stunning and rumbling waterfall is encountered after a gradual ascend, locally named as Dorberta. We will cross a small stream with the help of stones after the waterfall. After this the trail enters up to a forest which is covered up with bhojpatra trees(Himalayan Birch).

The short uphill trail takes us close to the har ki dun valley and a sudden change of surroundings can be felt. The majestic glacial mountains deliver proximate view and the river also accompanies us. The panoramic landscape of the heavenly scenery leaves first-time visitors awestruck. All the grand peaks are situated in such a way that it creates a scenario to relax and admire the beauty of the nature. In the center, Har ki dun peak standstill with ravishing colors during different seasons while towards it’s left lies the Hata peak and on the right lies the arrangement of Jaundar glacier and the mighty peak of “Swargarohini”.

Many people are mystified with the name of the river formed at this place, while the locals name this river as Thamsa, many trekking agencies mention it as Supin River. The thamsa river forms up from the streams flowing up from different regions of Jaudhar, Borasu, and Hata Glaciers.

If everything goes on as per our schedule, we trek towards Marinda tal. Marinda tal is 3 km away from the north of the Har ki dun valley. This lake is formed up by a huge boulder obstructing the stream which flows down from the Borasu pass. Covering up today’s magnificent topography in our senses, we trek back to our respective campsites.

Day 5:  Seematra to
  •  Trek: 3 Hours


Today we use the same route the one which we arrived from. Descending is not so time consuming as climbing uphill but you need to be careful while walking on the rocky terrain.

As we reach kalkatidhar, we spend a few minutes admiring and capturing the view around the place. Moving ahead on the trail we also spot two streams entering from the two different parts of the valley, Har ki Dun valley, and Ruinsara valley. The Har ki dun valley connects the Baspa valley through the Borasu pass and the Ruinsara valley connects the Har ki dun valley to Yumnotri valley through Bali pass. When we reach osla village, an ordinary lifestyle of Himalayan villages can be observed. You can chat with locals, visit old wood structure houses, or discover the heritage and culture of the community. Osla has a temple dedicated to lord Someshwara which is believed to be another form of Lord Shiva. In late August a festival is celebrated to worship lord shiva and people from nearby villages reach on foot to osla to celebrate this auspicious festival.

The Stare of the locales must be anxious but if you talk to them they are very warm-hearted and always welcoming to the outsiders. After spending a good time in the village we head down to the chilurgard campsite. The night halt will be in Chilurgad.

Day 6: Chilurgad to Sankri
  •  Trek: 4-5 Hours, Drive: 1 Hour


Today is the last day of trek. We leave from our campsite to start our trek towards sankri, the journey is mostly on a descending path. You need to be aware of descending tactics to avoid any leg injury. We walk step by step admiring the beauty and landscapes of the Valley. Finally, we reach back to taluka from where our vehicle takes us back to sankri. The day ends as we reach back to sankri.
