The Complete Guide to Borasu Pass Trek
Borasu Pass or Bara-su is a high mountain pass that is located on the border of Uttaranchal and Himachal Pradesh along the border with Tibet. It was an ancient trade route between Har ki Dun valley and Kinnaur valley. It is no longer used by the locals and is an escapade for trekkers and mountaineers.
The trek starts from Taluka and passes through the lush green Har ki Dun valley. Har ki Dun is a hanging valley in the Garhwal Himalayas, surrounded by magnificent Himalayan peaks and dense forests flocked with colourful birds and wild life. The trek starts by following the boisterous Har ki Dun Ganga and ends with the colossal Baspa River. One can stay in the Forest Rest House in leisure or camp near Har ki Dun Ganga. Also, one can camp near the beautiful glacial lake at Maninda Tal a few km from Har ki Dun.
The trail passes through glacier moraine, steep narrow ridges, sheer vertical snow slopes and boulder fields. All in all, it is a nerve-wracking trek – a stunning mix of backwoods and vast meadows, packed with spurting rivers and widespread glaciers, with a view of snow-capped peaks and massive boulders.
Har ki Dun is connected to Baspa Valley by the Borasu Pass. You have several passes that connect Uttaranchal to Himachal. Towards the north is the Lamkhaga Pass and towards the south are Kimalay or the Kimloga pass (no longer used), Singha and Rupin Pass, all of which lead to the Sangla valley. This valley is snow-covered from October to March.
The trek starts from Taluka, passing through dense forests consisting of chestnut, walnut, willow and chinar trees. The trek from Osla to Har ki Dun is through terraced mountain fields, lush green grassy patches and thick coniferous forests. As Har Ki Dun falls within the Govind Pashu Vihar wildlife sanctuary, chances of seeing wildlife are high. In the sanctuary, you will find trees of Bhojpatra, the rare Brahmakamal, and colourful flora and fauna. You can see various bids like Rosefinch, Redstart, Tit, Warbler, Babbler, Thrush and many more. One can see Kalanag, Bandarpoonch, Ruinsara peaks and the majestic Swargarohini even before he reaches the pass.
Har ki Doon is a valley of Gods (‘Har’ means Lord Shiva and ‘Dun’ means Valley) and according to the local folklore, this is the place where fairies congregate. It is also mentioned in our religious stories (epics) that Pandavas went to swarg (heaven) through this valley by climbing the Swargarohini peak. Duryodhana was once worshipped as a God by a few colonies here, and one can get to see the Duryodhana Temple in Osla. However it is now called Someshwar temple and calling it Duryodhana temple is taken as an offence. Though it is believed that once, the people of this region boasted of carrying Duryodhana blood in their veins. The area also acts as a base for approaching the Swargarohini peaks. We can also see the Bandarpoonch mountains, Ata peak, Kalanag or the Black peak and Bonga Peak.
An adventurous 6-day sojourn
If you’re in the mood for adventure, then perhaps this trek to Borasu Pass is what you need. But note that it’s a difficult and long trek. It is complete with all kinds of landscapes that may require you to use crampons, ice axes and glissade down vertical cliffs, bear the windiest campsites and wade through busy rivers. Situated on the border of Himachal Pradesh and Uttarakhand, close to Tibet, this virgin trail has rarely been explored.
Borasu is one of the four prominent passes of the higher region of Tons and Baspa glaciers. It’s a wonder why it’s rarely treaded on because it is a well-rounded trek that offers multiple landscapes.

Borasu Pass Trek Guide
Borasu is one of the four prominent passes of the higher region of Tons and Baspa glaciers. It’s a wonder why it’s rarely treaded on because it is a well-rounded trek that offers multiple landscapes.
The route to Borasu winds through the ancient valleys of Har ki Dun and Maninda lakeside. Both these valleys are bustling with life with green grasslands and wild alpine flowers. The best part if that the trails here are completely untouched. One can easily be charmed by the beauty of the magnificent virgin forest of Govind National Park. This feeling is further accentuated as you enter Maninda Valley, leaving behind most of the backpackers camping at Har ki Dun.
The glacial lakes of Maninda and Borasu are captivating and perfect for camping. The approach towards the pass-crossing is something that will stun any high altitude trekker. It is a dream traverse and not meant for the fainthearted.
Once at the top of the pass, enjoy the un-obstructed view of Sankri and Kinnaur side. The last day of trekking goes via the beautiful campsite of Bonga. Expect green meadows, milky streams, blue skies and snow-capped peaks as you reach Chitkul Village. Overall, it is a must-do trek for experienced trekkers.
Day 1: Getting to base camp- Sankri/ Taluka
Take an overnight train from Delhi to Dehradun. There are two night trains available from Delhi to Dehradun (check the ‘getting there’ tab for more details.) The drive till Sankri will take you through Nainbagh, Naugaon, Purola, Jarmola,Mori Naitwar (left from Naitwar will lead you to Dhaula, which is the base camp for Rupin Pass and Bharadsar Lake trek), and finally Sankri.
Sankri is a small village with around 250 houses. In peak season, it is usually bustling with trekking activity as it is the basecamp for many treks- Kedarkantha, Har Ki Dun, Bali Pass. Sankri has gorgeous views of Greater Himalayan mountain ranges. Walk through the village and learn about how the people live there. The peaks of Swargarohini shimmer in the evening sun, standing tall over the ridges beyond Sankri.
There is a four-wheel-drive road that connects Sankri with Taluka. You can hire a jeep (locally) for this, subject to the condition of the road. This is a landslide prone-route, and is often closed during the monsoons.
The trail to Taluka is almost level, going through 10-11 mountain bends. On the way, there are three big streams, almost submerging sections of the road in water. The hike is scenic, going past a series of wild roses and irises; bamboo, chestnut and cedar (deodar) trees. Just 2 km before Taluka, there is a campsite beside a stream. You can camp here if you’re hiking from Sankri.
Taluka is a small village with concrete houses. This is actually in contrast with the architecture in neighbouring villages like Sankri, Osla and Gangad, which are close to 300 years old. There is also a GMVN Guest house at Taluka for accommodation.
Day 2: Taluka to Seema
- Altitude: 7053 feet to 8530 feet
- Distance: 14-15 km
- Time taken: 6-7 hours
Taluka is a small, torpid hamlet with a few shops, hotels, forest rest house and stone shelters. Replenish your supplies here, as this is the last village on your way. There is no phone booth and you rarely have electricity in Taluka, so make sure you have charged your batteries and made your last phone calls before reaching Taluka. You get an amazing view of Har ki Dun Ganga River from the lawn of the Forest Rest house.
Take the trail that goes down next to the Forest Rest house. It is a well-marked trail because there are many villages until Har ki Dun valley and the trail is frequented by shepherds and locals. After 15 – 20 minutes, you come across a cemented track that leads to a bridge over a small stream. Cross the bridge and follow the trail keeping Har ki Dun Ganga River to your left.
You are just a few feet above Har ki Dun Ganga River, as you see the terrace fields of Taluka behind you. After 30 – 35 minutes into the hike, you see that the trail now passes through dense woods. You can see the river snaking through the woodlands below. Another 20 minutes into the hike, you come across a cemented bridge over the Har ki Dun Ganga river tributary.

Continue on the trail as it alternates between open valleys and dense woods. If the weather is clear, you can see snow peaks in front of you.
After 40 – 45 minutes through the woods, you come across a small shade provided for the travellers to rest. You can see Osla village at a distance. It takes another 20 – 25 minutes of hike before you finally reach Seema village. Seema is not much of a village as much as a place to halt. You have the Forest Rest house, GMVN Bungalow and a few hotels that provide food and arrange for your stay. Seema’s twin sister is Osla on the other side of the river. Osla has a satellite phone and is a big village. It is from Seema that climbers go to the base camp of Black Peak (Kala Nag, as it is known locally).

➤ How to Reach the Base of the Trek
To reach Dehradun
The best way to reach Dehradun is to take an overnight train from Delhi.
- 12205 Nandadevi Express – 23.50 – 3.55
There is a direct bus from Dehradun to Sankri. It leaves at 6 am from Dehradun Railway station. Be there by 5.40 am to get a seat.
If you are reaching Dehradun late, you can take a bus to Purola/Naugaon and then a connecting bus to Sankri. The last bus leaves from Dehradun Railway Station at 12 noon. If you reach Purola late, you can stay there overnight.
If you are taking a hired taxi, the route is pretty straightforward. First, head to Mussoorie, then move down to Yamuna Bridge, via Kempty falls. Then follow the Yamuna on your left until you reach Damta and further on to Naugaon. Cross the Yamuna at Naugaon and head towards Purola. The route immediately turns scenic, with pine trees overlooking the road.
At Purola break for lunch. From Purola, the route gets more mesmerising with the road climbing up and descending through thick pine forests until you get to Mori along the Tons River. (5 km out of Purola try to locate the south face of the Kedarkantha peak on your left. The highest peak, it is not difficult to spot.) From Mori, follow the Tons to Naitwar, again through some breathtaking mountain scenery. At Naitwar, the road branches off to the right along the Supin, until you get to Sankri an hour later.
➤ What to Pack for the Trek
- Trekking shoes: Carry trekking shoes and not sports shoes. The trail will be slippery at several places and will require shoes with good grip and ankle support. You can watch this video to learn to choose the right trekking shoes.
- Backpack (40-60 litres): A backpack with sturdy straps and a supporting frame. Rain cover for backpack is essential.
- Three layers of warm clothes: Carry two sweaters, and a padded jacket. If you are more susceptible to feeling cold, add another layer.

➤ How to Get Fit for the Trek
The Borasu Pass Trek is classified as a difficult trek. You trek up to an altitude of over 17224 feet. You have to make sure your lungs are strong for this.
On the Borasu Pass Trek, apart from huge altitude gains, the trails have rocky boulders and steep snow to negotiate. Hence, this requires a good amount of endurance. You can begin by jogging everyday. Start jogging at a slow pace and then keep increasing your pace day by day. Make sure you are able to jog 5 km in 30 minutes before the start of the trek. It takes time to be able to cover this distance in the given time. Swimming, cycling and stair climbing without too many breaks in between can help too.
This is another area you should work on. There is a lot of trekking distance that you will cover in high altitude carrying your backpacks. You have to walk on uneven terrain during the trek. It could be taxing for your legs. For this, strengthening your legs will help. You can do some squats to strengthen them. Do around 3 sets of squats, with 8 squats in each set.
Another aspect that will help you trek comfortably is flexibility. For this, you can do some stretching exercises – stretch your hamstrings, quadriceps, hip flexors, lower back muscles and shoulders regularly. On your trek, it is important that you arrive on the slopes with your muscles relaxed. Carrying a backpack, however light, can become a strain after a while. These exercises will help you to be in good shape before the trek.
Working out indoors
If you can’t go out and jog because of time and space constraints, here’s a video you can use to work out indoors.
➤ Alternative Treks by Indiahikes
A trek like Kugti Pass, which climbs up to 16600 feet is not exactly a trek that can be done without a support. It requires a team to organize the entire logistics end to end in terms of equipment, food and transport. And the success of the trek depends on having a strong team of trained and certified guides, trek leaders, cooks, porters, etc.. And equally important is safety measures and protocols followed over the course of the trek.
And though all the information regarding the trek is provided here, we do not recommend that you do this trek by yourself until and unless you’re a highly experienced mountaineer and so are the rest of the members of your team.
At the same time, we understand that you may wish to do this or similar ones but not have the right team (or are finding it difficult to organize one). In such a case you could go on some alternative treks that we at Indiahikes run.
Bali Pass makes for a great alternative for Kugti Pass. Like Borasu Pass, this too is a pass crossing that starts at Taluka . But what makes it extra special is the variety that the trek offers. You pass through ancient villages of Osla and Gangaad, meander next to the Ruinsara river on the trail followed by the glacial lake called Ruinsara Tal. All this before the pass itself. And then there is the pass itself. Nowhere else in the region could you experience the raw grandeur of Himalayas and gives a fantastic perspective of inner high region of the valley.In short, Bali Pass is the perfect alternative to Borasu pass.
