Har Ki Dun Trek Itinerary
Day 1: Drive from Dehradun to Sankri
190 km, 8 hrs
Meet at the starting point at Dehradun at 7:30 PM. After initial formalities, we will start our day with a drive to Sankri. The journey will pass through amazing views of mighty Himalayas. In the evening, reach Sankri. Checkin to a guest house and relax.
Overnight stay at a guest house.
Day 2: Drive from Sankri to Gangad and Trek to Osla
1 to 1.5 hours drive, 4-5 km trek, 6,725 ft - 8,270 ft
After breakfast, we board an SUV and drive through a bumpy road. We reach the village of Taluka in about an hour, which is the trek starting point.
We walk close to the river Supin gushing through rapids. Under the shade of walnut, pine, and cedar trees, the walk is quite pleasant. In autumn we can often find walnuts lying around. One must avoid “bichchu ghas” which literally translates to ‘scorpion grass’. A slight touch can give us a stinging sensation which lasts for about twenty to thirty minutes. This herb is also cooked as a vegetable and eaten. Often the passing villagers greet us on the way. High up above on the true left, we get to see the village of Datmer. It is lined by a series of step farms. The farms have the bright red colored Cholai growing from late monsoon to early autumn.
We continue our trek and soon we reach the secluded campsite.
Overnight stay at a camp on twin-sharing basis.
Day 3: Trek from Osla to Kalkatidhar
5-6 km / 8,270 ft - 10,830 ft
Today we start the day by heading up towards Osla village, which is located on a sloping spur about a hundred meters above the river Supin. The initial trail to Osla is the steepest section along the entire trek and can take 30-40 mins to cover. The landscape surrounding Osla is full of terraced farms. The colors of these lands differ in every season. The red farms of Cholai (Amaranth) look amazing and can be seen from the late monsoon.
This grain is a powerhouse with its rich nutritional values and a favorite among the locals. Apart from these Kidney beans in wide varieties are cultivated in the area. Osla is the last village on the route to Har ki Dun. From Osla the trail gradually rises higher and we cross a few fields, while the river can be seen far below. We come across a temple some distance below the trail towards the right. We pass through bushes of flowers like orchids, fleece flowers and sunflowers.
The journey today is rather short, which gives the opportunity to acclimatize to the high altitude and prepare for the next days journey. We can take a breather basking in the sun at the beautiful campsite of Kalkatidhar. The ban to camp at Har Ki Dun has had a rather positive outlook to the trekking itinerary, as it allows for more comfort & at the same time preserves the natural beauty of Har Ki Dun.
Overnight stay at a camp on twin-sharing basis
Day 4: Trek form Kalkatidhar to Har ki Dun & Marinda Tal, return to Boslo
10.5 km, 5-6 hrs / 9,977 ft to 11,600 ft to 10,412 ft
The day's trek can be considered to be rather long as we today visit Har Ki Dun and Marinda Tal, a small lake formation due to the obstructing boulder across the river stream, which lies 2 KM further ahead of Har Ki Dun. As we start the trek, at a short distance a hidden and roaring waterfall is encountered with a small tea shop beside the waterfall.
The ascending path offers stunning views above the confluence of the Supin and Ruinsara rivers. From here, you can admire the snow-clad peaks of Ruinsara Valley, notably Black Peak, the highest in the area. To the north, the Har Ki Dun valley unfolds in the distance, with a clear view of the Forest hut. Continuing higher on the right of the river, you enter a final stretch through a beautiful forest. Emerging from the woods, you arrive at Har Ki Dun’s main camping area, nestled beside a babbling stream. This panoramic spot sits at the junction of two valleys, one originating from Jaundhar Glacier and the other beyond Hata Glacier, offering a breathtaking natural spectacle.
We can choose to relax and soak in the environment for some time or we can continue our trek to Marinda Tal, in the north, just 2-3 km away from Har ki Dun. The trail is gradually ascending here. It is a small lake formed by a huge boulder obstructing the river which flows down from the base of the Borasu Pass.
After our short visit to Marinda Tal we make our return journey back to Kalkatidhar. We take the same route and it becomes much easier as its all downhill from here. We reach back by early evening and rest at the campsite.
Overnight stay at a camp on twin-sharing basis.
Day 5: Trek from Boslo to Devsu Thatch
5.1 km, 4-5 hrs / 10,502 ft to 9,878 ft
The journey back to Osla is an easy walk. On the route we come across a good view of the trail all the way to Osla and see the valley descend towards Taluka, around the curve of the ridge where the two streams comng from Har Ki Dun and Ruinsara respectively, converge. A little short of this intersection we can get a glimpse of a trail to our left marked by a sight of a bridge down over the stream.
This trail goes to join the trail to Ruinsara lake and is rarely taken. After reaching Osla, one can roam about in the village, talk to locals and soak in the Garhwali culture. We continue our journey from here to our earlier campsite of Puani Garat where we can spend time basking in the sun.
Overnight stay at a camp on twin-sharing basis.
Day 6: Trek from Devsu Thatch to Gangad, Drive to Sankri
7-8 km, 5-6 hrs / 9,878 ft to 7,709 ft to 8,265 ft
Early in the morning, post breakfast we set out from this beautiful abode as we start trekking through the same trail we trekked along on Day 1, towards Taluka. Although the views seem different as the perspective changes significantly trekking downhill. The walk takes lesser time than before and is enjoyable. We walk to the true left of the River Supin until we finally arrive at Taluka, from where a vehicle takes us back to Sankri. We retire for the day in camp alongside the river or in a guest house in Sankri.
Day 7: Drive from Sankri to Dehradun
190 km, 8 hrs
The trek to Har ki Dun concludes today as we leave Sankri. The drive up to Mori through the unique lesser-touched regions is still amazing. The stretch right after crossing Mori town is still the prettiest along the entire journey, albeit the new hydel project has put the fragile environs at increased risk in this area. Rafting and Kayaking which was earlier prevalent here are no longer feasible. Regardless the beauty of the region remains to a significant degree. After crossing the towns and finally Kempty-Mussoorie, we reach Dehradun by late afternoon or early evening.
