Brief Description
Location: Uttarakhand
Altitude:5360 m
Duration:10 Days

Located along the border with Tibet, the Borasu Pass trek is a virgin trail which presents some of the best views of the historical Swargarohini peak. As a new trail in our portfolio, what we are most excited about is that it is one of the lesser explored trails in the region connecting two very distinct valleys of two geographically rich states. Borasu Pass trek starts from the small village of Sankri in Uttarakhand and ends at the gorgeous hamlet, Chitkul, tucked away in the many folds of the mountains in Himachal Pradesh. The trail for this high mountain pass takes you through the infamous Har ki Dun Valley. With an abundance of fauna housed by colourful birds and surrounded by splendid peaks, Har ki Dun is one of the most beautiful all-season treks in the Himalayas. The Borasu Pass trek gives you the opportunity to continue on this exquisite trail onto a lesser explored route to the pass which connects Tons Valley in Uttarakhand with Baspa Valley in Himachal Pradesh. It being an extension of one of the most beautiful trails, is only one of half a dozen reasons you should consider this trek as your next adventure! 

This ancient trade route between Uttarakhand and Himachal offers you a variety of landscapes that are sure to leave you awestruck. Passing through small mountain habitations of Taluka, Gangaad, Dhatmir, Seema and Osla, the trek takes you through dense forests rife with chestnut, walnut, willows and chinar trees. It passes through an assortment of landscapes such as terraced mountain fields, massive patches of tall grass and thick coniferous forests. Our favourite part about this high-altitude pass, which lies barely explored at an elevation of 5,200M; is that it provides for the best views but will make you sweat for them! 

A stunning mix of green meadows and vast fields of snow, packed with jumpy rivers and solemn glaciers, Borasu Pass is an easy trek made extremely difficult by its treacherous terrain. As we were walking the trail, the one thing that struck us was that this trek is a complete 360-degree ride. Starting from greens leading into browns spilling into whites it takes a turn-around after the pass, to go from whites to browns to eventually reach the lush green valley by the Baspa river into Chitkul in the Kinnaur district of Himachal Pradesh.

It is a difficult climb, however. The long distances between camps, steep narrow ridges and its heavily bouldered terrain with patches of glaciers full of open and hidden crevasses, all lend to making it a strenuous affair. Its steep ascends and descends and the high altitude can get technical and hence we believe that the trail demands prior experience in the Himalayas along with some specific skills.

From our explorations, the best months to undertake Borasu Pass Trek are May, June, September and October. Stay on this page for more information on the Borasu Pass Trek.

Day 1

Make your way to Sankri (1,920M)

Distance: 185kms drive

Time Taken: 8-9 hours

If you have signed up with Bikat for a drive from Dehradun to Sankri, our day starts early. All of us assemble at the meeting point by 7 in the morning so we can start our long drive up to Sankri – a trekking hub in the Garhwal region of Uttarakhand. Although there’s nothing more on the agenda for today other than the 9-hour drive and settling into mountain air, it is better to leave as early as possible for two reasons:

One, so we can reach as early as possible and give our bodies enough rest for what’s coming the next day. And, two, roads on the mountains are unpredictable and it is always better to account for delays when we start. It is also better to reach before it gets dark.

Sankri is a head trail for a lot of trekking routes and is bustling with trekkers across the year. Popular trails such as Har ki Dun, Baraadsar Lake, Bali Pass, Kedarkantha, Dev Kyara, Phulara ridge to name a few, all start from this scenic village centered in the background of some of the most splendid mountains in the region.

The drive from Dehradun takes us on scenic mountain roads. If you have the slightest motion sickness, the smooth roads can easily make your head spin with its curves. The ever-changing landscape with each turn, however, is a good way to keep yourself distracted. Tall trees, massive fields and entire mountain faces cut into steps for farming are views you wouldn’t want to miss for some shuteye. The drive takes you through some very big towns but also alternates between small patches of busy roads with village shops and long empty stretches with nothing but the sound of the wind and the birds.

The constant shift between the noise and the calm has a different sense of serenity attached to it. What’s even better is that breakfast and lunch, in local dhabas along the way make sure we get to indulge our tastebuds in some locally popular cuisine. The last two hours of the drive take us through a smooth road lined with thick forests on both sides. The sparkle of the forest is enough to refresh us from the long drive to get to our destination. Sankri is a head trail for a lot of popular treks and hence is not short on facilities. Although there is no phone network in Sankri, you can probably find a shop in the market which will be happy to loan you wi-fi in case of an urgent need.

Waiting for us, at the end of the trail of this back-breaking journey will be a warm, wooden homestay with cozy rooms and a home cooked meal. Expect to reach latest by 7 PM.

If you have not opted for travel with Bikat from Dehradun to Sankri and are to meet the group directly at the head trail, check out the article on how to reach Sankri (click here) for any assistance. Do plan your travel so as to reach Sankri latest by 7 in the evening. (Please note: Bikat can arrange for your transport for an additional cost as mentioned in the Add-Ons section above.)

Day 2

Sankri (1,920M) to Seema (2,260M) through Taluka (2,100M)

Distance: 12 kms drive to Taluka, 10-12 kms trek to Seema

Time Taken: 3 hour drive, 5-6 hour trek

Today is an early day because there is much ground to cover. We should be done with breakfast anytime between 7-8 AM which gives us enough time to soak in the morning sun and the beauty of this mountain town before we leave for the day by 9 AM.

There is a narrow kaccha road that can be covered on wheels. Do not, however, expect this to be a quick drive – we are likely to encounter JCBs shoving parts of fallen mountain off the narrow roads on multiple patches all through the 12 km stretch. The drive should take anywhere between 2-3 hours based on how many times we have to wait for the road to clear. The waiting does not seem too tiresome for the fresh water streams with fantastical views of the forest and mountains. A deep gorge with a stream(nalla) flowing underneath is invigorating. The nip in the air keeps your senses active and the mind, refreshed.

At the end of the road is a small mountain village named Taluka, bursting with colours. You will know you have reached when you see rows of mules standing obediently in a line, facing the mountain and about a dozen tiny canteens lined up to serve you hot food in case you shall need it before your trek! A lot of popular treks like Har ki Dun and Bali Pass start from here, so it is forever bustling with the contagious energy of trekkers.

After breakfast and picking up our packed lunches for the day, we set off towards Seema which is going to be our first campsite on this trek. Although we are not gaining much altitude today (just 160M from Taluka to Seema), the length of the walk is the real challenge. The trek starts on even land with a strong smell of the forest in the air; the lush landscape adorned with waterfalls by a half dozen. The land is mostly even, save the jumping over massive fallen trees and big boulders. The inclines otherwise are gradual with the grayish blue of the boisterous Supin river following alongside as a faithful companion.

After an hour of climb we reach our first clearing out of the forest. You will see two dome-like structures built as a stop-and-rest space to keep you from the harsh sun. Another hour into the trek and the trail opens up on one side to expansive views of the valley. This is when we hit our first patch of steep incline which will take all of 10 mins to cover but is efficient enough to make you stop for a breath or two. The next hour seems like quite a relief, then, for it being a flat land with a few humps along the way. It’s a steady incline from here on. We hit one more food joint one hour away from the campsite – stack up on some energy if the trail’s knocked some air out of you.

The forest floor is wet and mucky and gets slippery. Remember to walk carefully. The shiny dots you see covering the mountain faces on the opposite side are houses of entire villages resting precariously on these rugged slopes. The only traffic jams you are likely to encounter on these routes are cows going about their business for the day as you try to squeeze through the crowds of them on these narrow trails.

Expect to reach the campsite latest by 6 in the evening after a 6 hour trek. The 2 km stretch of the long camping ground has rooms available with views of the mountains.Take your pick of the view you want to pitch your tent to and rest your weary self for the night.

Day 3

Seema (2,260M) to Har ki Dun (3,510M)

Distance: 16 kms

Time Taken: 7-8 hours

Since we are gaining a fair bit of altitude today (1,250M), we follow the same schedule as yesterday – an early start after an early breakfast. The trail continues on the terrain from day 2, on a wet, stone-paved surface with a slippery personality. As soon as we start the trek, we cross a small village. There are plenty of water streams on the way today. Forty-five minutes into the trek we reach a suspension bridge to cross over to the other mountain which is followed by a twenty-minute steep ascend to reach flat land again. At the end of the ascend, you would have made it out of the area rife with tall trees and into much wider valleys with smaller shrubs and expansive views. It is a gradual but continuous ascend from here on.

As the sun comes to its highest point for the day, we are treated to our first sight of the mythological giants Swargarohini and Bandarpoonch peaks and the infamous Black Peak. This is also when we hit a patch of flat ground so we can admire these marvels while also continuing to cover some ground. The respite, however, is short-lived. Steep ascends start again after 10 minutes and continue on for an hour and a half. Just when we thought we would have gained enough height for the day, our heart sinks to find out that the next patch is a steep descend where we will lose a lot of the height we had earned in the past few hours. The beauty of the trail starts to get thicker as we move on – two hours after noon you will find yourself walking amongst plants taller than yourself, fanciful with all their green, flowy leaves.   

The landscape changes face quickly from here. Suddenly out from feeling closed in by the tall trees, we find ourselves amongst shrubs growing in all directions. The warm colours of the landscape, and flowers (red orange yellow - the whole spectrum) automatically make you feel warm stripping the cold air off some of its power. The trail is rich in variety of leaves and bushes - the valley a messy wardrobe of rich and colourful flowers scattered on the ground in no specific order. The route has you witness mountains of all kinds, from naked, vertical rockfaces using the sun as their personal reflectors, to greens on the foothills and the brown scree sliding down the gentle slopes like oily sweat.  

If you have ever walked the Har ki Dun trail, you will know the insurmountable beauty and the pleasant performance this valley has to offer. Expect to reach the campsite latest by 4 in the afternoon. Make sure to open your tents towards Swargarohini so you can enjoy its beauty and might as you sit next to the cold water of the Supin river and sip on some fuming tea. Could there be anything better to chase the weariness of the day away? If you feel the quietude of the place is too much to take, the soft sound of the gushing water will be your best comrade through the night.

Day 4

Har ki Dun (3,510M) to Ratha Tho (4,110M) via Morinda Tal (3,800 M)

Distance: 5 kms

Time Taken: 3-4 hours

Today is when our excitement sees a new height since this is the beginning of that trail – the one that goes beyond! Today is when we take the road less travelled and go beyond Har ki Dun. It is a lax day, there is not much ground to cover and the terrain is fairly simple. We even have enough time to go exploring this beautiful valley of the Gods (Har ki Dun). Go up the mountain on the other side of the river to get a more unobstructed view of the mythological giant, Swargarohini and the exquisite world the heap of rocks was loyally guarding.

We start on our journey ‘beyond’ anywhere between 9 and 10 AM. The first thing we notice as we start for the day is that the crowds have already started thinning out since we are now heading out of the popular trekking route towards a more virgin land. The drama of the high mountains wearing clouds like crowns and the sunlight peeping out from behind them like a shy kid not wanting to come out but afraid of missing all the action only has us as its sole witness in this unmapped territory. It’s like you own the view like you do in a heated argument.

The first hour of the climb is a steady but gradual incline which is followed by 20 minutes of flat ground that will bring us straight to Morinda Tal. This is yet another exciting feature not many get to witness despite being so close to Har ki Dun. This lake which sits still, bang in the middle of the restless winds, swaying grass and rocks; stands out as much for its tranquility as for its turquoise colour. The wide, open field is home to abandoned stone structures used by shepherds as shelters. The valley in front now changes color, suddenly turning brown with short blades of dry grass – no shrubs either.

Ten minutes into this valley we hit a ten-minute patch of big boulders which on successful crossing leads us to a patch of flat land and then a steady incline. Walking through the Morinda valley is literally a walk in the park. And since it is a fairly easy day, we take some time to lie on our backs in the dry grass and look up to the sky. When you do that, you will see the clouds idly rolling past the high mountains before they slowly dissipate into thin air. To witness this phenomenon, on loop, is nothing short of magical.

The gradual 600M of height gain through wide meadows today couldn’t be more relaxing. From green to the land of golden, we have now entered the zone which can support very little life. The trail after the lake is gentle humps through golden meadows with a few wildflowers still holding strong in this cold land. After joyously taking your time on the trail, expect to reach camp just in time for hot lunch.

Day 5

Ratha Tho (4,110M) to Saunbhera (4,400M)

Distance: 6 kms

Time Taken: 3 hours             

Today is again a short day with a 300M altitude gain across 6 kms. Given the altitude and the cold, we will wait for the sun to come out before we start the day. As the crowds on the way to these popular treks start to thin, so does the vegetation on the route, flipping the entire vibe of the trek on its head. There’s only scree, moraine and boulders till our eye can see - glaciers in the distance and absolutely no grass, even the dry grass has now retired. We have crossed very quickly from the tree line to dry grass to an absolute absence of vegetation.  

The first half hour of the trek is through boulders post which a gradual ascend begins. If we’d thought Har ki Dun was pretty, it only gets better from here! We, for one, had not expected this unfettered lay of beauty that we were now witnessing. Tiny specks of pollen flying in the air like snowflakes, streams spread across the land like veins of the earth. Triangular rocks and mountain faces with sharp edges look like Picasso paintings from his Guernica period. Two hours after we started to ascend, we hit patches of descent. The valley takes sharp turns and changes direction a lot of time. The river here wears an even deeper colour. The sound of dry leaves crushing under your legs and the texture of the rock as you run your hands on its surface are some sensations you might want to experience. The feeling when the ground is mushy and holds you in your place like it’s telling you to go no further, is surreal. The last 10 minutes of the trek before we reach the campsite for today at the foot of the glacier is on a zero-degree gradient. It is a pleasant change after having to maneuver through boulders for the rest of the trail.

This campsite with a direct view of the route to the pass seems a stone’s throw away from here but is actually hours of climb. But that’s our worry for another day. For today, we spend the rest of our time acclimatizing to the thin air and exploring the vast, open ground to discover its various colours, textures and shapes. And to do it, without no one around is only an added advantage.

Day 6

Saunbhera (4,400M) to Borasu Pass Base Camp (Upper Lamjung) (4,730M)

Distance: 3 kms

Time Taken: 2 hours

Today is the shortest day on the trek. We leave late after the sun makes an appearance and reach before lunch. The trail is all boulders which is good practice for what’s to come the next two days. Crossing the flat land of the campsite takes only a few minutes before we reach the foot of the boulders and start our climb up. We follow a narrow ridge all the way up to the small space which will be our campsite for tonight. One and a half hour into the climb, we will reach the top of the first ridge. Take a few minutes to rest and get a bird’s eye view of the campsite of Saunbhera, where veins of streams divide the land into geometric shapes – the flat ground appearing as hexagonal grasslands below. It was one sight we couldn’t tear our gaze away from. After a few minutes of straight walk at the end of the first ridge, we begin incline on the second and the last ridge which should take about half an hour to cover.

The base camp for the pass is called Upper Lamjung. Lamjung, in local language, means ‘Long Moustache’ named as such for the shape of the lower ridges and how they appear from below. Expect to reach the Upper ‘long moustache’ within two hours. The campsite is compact and tricky to set up. It is uneven and full of rocks. Take it from us when we say this is not going to be one of your most comfortable nights in the mountains! The pass hides behind the many folds of the glacier in this area. The campsite here is pretty exciting for it is protected by rockfall by a dip in the terrain. While the dip can keep the rock away, there is no way to stop the continuous sound of the rumble of rocks falling hither thither.   

The terrain around us is stunning. If you stand with your back to the campsite, to your right are gentle slopes of mountains of varying hues and to your left are intimidating structures with pointed ridges and falling rock. If you get a clear sky, you will also get a bird’s eye view of the many glacial lakes sitting idly in the distant landscape. 

The ground on the base where we set camp looks like fallen rocks someone pushed off a pile. Cloud forms dissipating and melting into the next form, taking on different personalities - you could spend hours looking at the shapes and structures around you. The only sound that will consume you though is the rumble of rockfall somewhere in the area once every few minutes. There is a thick layer of ice on the upper half of the mountain, you can hear the sound of water but have to go hunting to actually find it.

The way up from this point has so many rocks, it looks like ruins from a well-built civilization from far back in history.

Day 7

Upper Lamjung (4,730M) to Bonga (4,500 M) via Borasu Pass (5,200 M) 

Distance: 10-11 kms

Time Taken: 10 hours

Today is ‘the day’ and it is going to be a long one – 500M up to the pass and a descend of 700M from the pass on to the next campsite. We start as early as possible, even before the sunlight starts chasing peaks, slowly creeping up on one mountain top after another as they shed off their darkness little by little. An hour into the steep, heavily bouldered climb, we reach the base of the glacier. This is where we will gear up – put on our crampons/ microspikes. The slope of the glacier is not more than 30 degrees as it starts but very quickly turns into 70 degrees with alternating rock and snow patches a little further up. The last bit up to the pass is almost vertical and can feel a little intimidating.

The ascend is not the major challenge for the day. We reach the pass in less than 3 hours. The view from the top which lies at the daunting altitude of 5,200M is mesmerizing. Snow covered peaks with browns and whites playing chase with each other forming peculiar patterns on the high mountains all around. After a small prayer on the pass, we start the difficult part of the journey – the long and arduous descend. The first bit itself looks like a direct drop. It will require roping up or fixing ropes for a safe descent. The initial section, which is a 75 degree slope takes close to 40 minutes to descend. Post this, we hit a large patch of almost flat snow which slowly descends downwards. This section has a lot of open and hidden crevasses, however, and needs to be crossed with caution. It also has sections with steep slopes on one side which could take you straight down, in case of a single slip. By the end of 45 minutes on this terrain, we would have already descended 300M and reached the end of the snow section.

What comes next is especially daunting– hours of sharp ascend and descend on boulders as big as dreams. The need to exercise caution on every tiny step forward, to avoid the gaps between these boulders, is extremely tiring. The next section which brings us down by 200M looks like a small distance to cover but takes close to an hour and a half. It is a steep descend with no specific trail and requires navigating massive boulders. Given that this is a fresh trek not attempted by many, the route has no marked trail which was our favourite part since it gave us a free reign to explore.

Once at the base of this section, we will walk for 45 minutes on the rocky ground to make it to the mountains on the other side of the glacial bed. We need to catch the ridge of the mountain you see ahead. But in order to do that, we have to climb up a steep slope of scree and loose rocks. This section which will take not more than 50 steps to climb might make you think 50 times before you do it. Once on the ridge, the walk is pretty straightforward, although it is on a narrow trail with loose rocks, so you might want to be extra careful. Half an hour on the ridge and the landscape starts to fill a little with colour. The snow-capped peaks are now pushed into the backdrop. Streams can be seen and not just heard.

After walking the ridge and welcoming colour back into our field of vision for 45 minutes, we descend to take the lower ridge. Flowers get added to the mix of dry grass and life is starting to thrive in this terrain. Expect to reach the campsite for today by early evening. The campsite is in warmer lands with plentiful colours and a stream flowing by our tents. The temperature, however, is still low – do not be surprised if you wake up to a sheet of ice keeping you from getting to the water of the stream, like it did us!

Day 8

Bonga (4,500 M) to Chitkul (3,280 M)

Distance: 14kms

Time Taken: 8 hours

Today is a long and hard day too, firstly because of the distance and secondly, for the difficult terrain. Since the previous day was wearisome, today might seem a bit harder. We leave after breakfast by around 9 AM. Carry sufficient water with you since the first water source is 2.5 hours away. The terrain for today includes a fair bit of steep ascends and descends, all on massive boulders across an exposed mountain face with a steep drop. There is no specific trail which makes things harder. This challenging terrain full of boulders reaches its end by 12:30 AM, as you start seeing some vegetation and finally find flat and firm land to walk on. An hour and a half more and the tree line starts to appear. We could hardly contain our glee when we heard the crispy yellow leaves of entire mountains full of Bhojpatra trees make music in the air. Walking through thick, golden forests of Bhojpatra is extremely refreshing after the cold terrain we spent hours on. 

An hour more and we reach open grasslands with huge humps taking us up and down - but the warmth of seeing life around us on these small hills keeps this a breezy walk. Once we make our way down to the river bed, there is one more small section of walking on rocks. By 04:30 PM expect to reach a small wooden bridge which takes you away from the mountain onto smooth roads on the other side of the bridge.

Chitkul, which is the end point of the trek is a two-hour drive from here. Accommodation for the night will be provided by us.

Day 9

Depart from Chitkul (3,280M)

This day is not included in the fee. In case you book your transportation from Chitkul to Shimla with us, a taxi will pick you up from the guest house early in the morning. The drive to Shimla will be for 10-12 hours. Expect to reach Shimla by evening.

Day 10

Reserve Day

Since it is a high altitude trek where the weather conditions tend to get unpredictable, we have an extra day just in case we might need it. This will only get used if unexpected and unforeseeable conditions present themselves at the last minute.

If the buffer day is used, you have to pay Rs. 3,500 per day (INR). The amount will be collected by the Trek Leader.

Why Bikat?
Learning Experience

We are an Adventure Learning Organisation first. We want you to not just complete a trek safely but also pick up some basic trekking knowledge and skills along the way. To achieve this we have integrated learning modules into our itineraries. These modules will help you build the necessary skills to progress from trekking to mountaineering over time.

Personalized Attention

Our group sizes on treks don’t exceed 15 members in order to maintain a healthy Participants : Leader Ratio of 8:1. Over time we have found this number to be optimum when it comes to ensuring personalised attention to every member of our group. On mountaineering expeditions this number is even smaller. Our group sizes are capped at 12 members ensuring a Participants : HAP Ratio of 2:1.

Best Expedition Leaders

Our Expedition leaders are advanced mountaineering course qualified, specially trained in rescue procedures from NIM and certified first-aid responders. Even our local guides are certified first-aid responders.

Eco-friendly Practices

Group sizes are capped at 15 people. Batch sizes are capped at 250 people per trail per season. We follow a rolling campsite model. We are constantly exploring and introducing new trails to reduce the burden on existing ones.


For us, a successful summit is not about reaching the highest point of a mountain but about making it safely back to base. Every region of ours is mapped with an emergency evacuation plan. The equipment we use is UIAA certified. Our trek leaders are AMC certified with specialisation in rescue procedures. Our support staffs are trained in first aid as well.
