Sar Pass Trek Guide: A Snow Crossing in Parvati Valley

Introduction

The Sar Pass trek is a snow crossing, not a meadow stroll. That is the single most useful thing to know before you book it. You start at Kasol at roughly 1,700 m and finish five days later having stood on a pass at 4,220 m with snow underfoot for the last two days of the walk. Wikipedia records the elevation as 4,220 m (13,850 ft), in the Parvati Valley of Kullu district, Himachal Pradesh.

Not Kashmir. Not Uttarakhand. Kullu.

The name comes from the terrain. "Sar" means lake in the local dialect, and the pass is named for a small, usually frozen lake you walk past between Tila Lotni and the Biskeri ridge. That lake stays frozen well into summer, which tells you something about the conditions up there in May.

This trek has a reputation as a beginner trek. It partly deserves it and partly does not. The gradient is forgiving for the first two days. The climb from Min Thach to Nagaru is not. And the Parvati Valley has a documented safety record that no honest guide should skip over.

Quick Overview

Item	Detail
Location	Parvati Valley, Kullu district, Himachal Pradesh
Pass altitude	4,220 m / 13,850 ft per Wikipedia; Indiahikes documents it as 4,200 m / 13,799 ft
Distance	Approximately 49 km across five trekking days, per the Indiahikes stage table
Duration	5 trekking days, 6 to 7 days including travel
Difficulty	Indiahikes grades it easy-moderate for fit beginners. Treat that grade with caution
Start point	Kasol (about 1,700 m)
End point	Barshaini / Bursheni (about 2,400 m), the last motorable village in the valley
Best season	May, essentially. Spring, with snow in the higher reaches
Nearest airport	Bhuntar (KUU), about 30 km from Kasol

On the pass altitude, sources disagree by about twenty metres. Wikipedia's infobox gives 4,220 m. Indiahikes documents the Day 4 high point as 4,200 m and elsewhere on the same page writes 13,799 feet and 13,800 feet. Use 4,220 m as your headline figure since that is the encyclopaedic reference, and understand that the difference is within surveying noise.

Stage altitudes, from the Indiahikes documented itinerary:

Stage	From → To	Altitude	Distance	Time
Day 1	Kasol → Grahan	1,700 m → 2,350 m	10 km	4–5 hr
Day 2	Grahan → Min Thach	2,350 m → 3,400 m	7 km	4–5 hr
Day 3	Min Thach → Nagaru	3,400 m → 3,800 m	8 km	4–6 hr
Day 4	Nagaru → Sar Pass → Biskeri Thach	3,800 m → 4,200 m → 3,350 m	14 km	6–8 hr
Day 5	Biskeri Thach → Bursheni	3,350 m → 2,400 m	10 km	4–5 hr

Spellings wander. Min Thach appears as Ming Thach and Minh Thatch. Bursheni is also Barshaini. Wikipedia's camp list adds Padri and Bhandak Thatch, which most commercial itineraries skip.

Where Sar Pass Actually Is

Parvati Valley runs east from Bhuntar, up past Jari, Kasol and Manikaran, ending at Barshaini where the road stops. Sar Pass sits on the ridge system south of that valley floor, between the Grahan side and the Pulga side. You climb out of one arm of the valley, cross the ridge, and drop into another.

Kullu district. Himachal Pradesh. If you have seen Sar Pass filed under Kashmir on a listicle or an old topic list, that is simply wrong, and it matters, because the permit regime you need to comply with is Himachal's, administered by the Kullu district administration and the Parvati Forest Division.

The valley itself is one of the most heavily trafficked backpacker corridors in the Indian Himalaya. Kasol in May is loud. That is part of the appeal for some people and a reason to leave early in the morning for others.

How to Reach Sar Pass from Mumbai

By air to Bhuntar, then road. Bhuntar Airport (IATA: KUU), also called Kullu-Manali airport, is the closest strip. Kasol is about 30 km from Bhuntar. Flights from Mumbai route via Delhi, and the runway at Bhuntar is short and weather-sensitive. Cloud and rain cancel flights here with some regularity. Book the first slot of the day.

By air to Chandigarh, then road. This is what I would actually do. Mumbai to Chandigarh is a direct flight of roughly three hours. From Chandigarh it is a long road day to Bhuntar and on to Kasol. HRTC and private Volvo buses run this corridor. Chandigarh is also the nearest international airport to the valley.

By air to Delhi, then the overnight bus. Delhi to Bhuntar by road is the classic budget move. Volvo buses leave Delhi in the evening from Kashmere Gate or Majnu ka Tila and reach Bhuntar around breakfast. From Bhuntar, local buses and shared taxis run up the Parvati Valley to Kasol. Wikipedia puts the Delhi to Manali road distance at 566 km, and Bhuntar is short of Manali on the same highway.

By train. Kasol is not easily approachable by rail. The nearest broad gauge railheads are Chandigarh (about 275 km), Kalka (about 310 km) and Pathankot (about 325 km). None of them is close. Direct Mumbai trains to Chandigarh exist but the journey runs well over a day, and you still have a full road day after that. Fly if you can.

Final leg. Kasol to the trailhead is a walk. The trail to Grahan starts from Kasol village itself, crossing the Parvati and climbing along the Grahan nala.

How to Reach Sar Pass from Pune

Pune does not have a direct flight to Bhuntar. Two shapes work.

Pune → Chandigarh → Bhuntar → Kasol. Direct Pune-Chandigarh flights operate most days. From Chandigarh you take a Volvo or a taxi. This is the version that avoids Delhi entirely and it is the one I would pick.

Pune → Delhi → Bhuntar → Kasol. Fly Pune to Delhi in the morning, spend the day, take the evening Volvo. You arrive in the valley the next morning. It is cheap and it works, but you spend a night sitting upright and you should not start walking that same morning.

Either way, build in a night at Kasol before Day 1. You will need it for altitude and you will need it for the permit paperwork.

The Route, Day by Day

Day 1: Kasol to Grahan. Ten kilometres along the Grahan nala, gaining about 650 m through pine and deodar. Easy going. Grahan is a genuine working village, not a campsite invented for trekkers, and the walk in follows the water most of the way. Four to five hours.

Day 2: Grahan to Min Thach. Seven kilometres and a thousand metres of gain. This is where the trek turns into a trek. You climb out of the forest and onto the first open meadow. Min Thach at 3,400 m is a shelf with views back down the valley and this is the first night where cold becomes a real factor.

Day 3: Min Thach to Nagaru. Eight kilometres, 400 m of net gain, and the most dangerous stretch of the whole route. Indiahikes describes this section plainly: the slope falls steeply to the valley below and may be slippery, and the trail, even if marked, may not be visible under snow. Nagaru at 3,800 m is an exposed campsite on a ridge. It is cold, it is windy, and there is no shelter. People sleep badly here.

Day 4: Nagaru to Sar Pass to Biskeri Thach. The big day. Fourteen kilometres, six to eight hours, and the only day that actually crosses anything. You start before dawn because the snow is firm early and turns to slush by mid-morning. The climb to the pass is a snow slope. At the top you pass the frozen Sar itself, the small lake that gives the pass its name. Then you go down, and the way down is the part everyone talks about.

Day 5: Biskeri Thach to Bursheni. Ten kilometres of steep descent through dense forest. There is a rope section on this descent, roughly twenty feet down rock to reach a stream crossed on wooden planks. Take it seriously. The trail then passes a Forest Department lumber yard and follows a water pipeline into Pulga. Pulga and Tulga are twin villages separated by a stream. From Tulga you cross a bridge over the Parvati, which is dammed downstream for the hydroelectric project, and you are in Barshaini.

Barshaini is the last motorable village in the Parvati Valley. Buses and taxis run from there down to Kasol and Bhuntar.

Permits & Booking

This is the section that most Sar Pass articles are ten years out of date on.

Trekking Management System registration is compulsory in Kullu district. The Himachal Pradesh Tourism Department launched the TMS portal at trekking.hp.gov.in, live from 15 July 2022. As reported by The Tribune in September 2022, the Kullu District Tourism Development Officer stated that no trekking activity would be allowed in the district without registration on the portal, that no adventure tour operator would be allowed to provide trekking services without registering on it, and that individual and group trekkers were also advised to register themselves.

Forest Department permission is required between 9,000 and 15,000 feet. On 17 September 2022 the Kullu Deputy Commissioner, in his capacity as Chairman of the District Disaster Management Authority, issued an order stating that no trekking will be allowed between 9,000 and 15,000 feet without the permission of the Divisional Forest Officer. Above 15,000 feet requires special permission. The DFO is required to inform the Director of experienced daily, and the DDMA must also be informed. The order also requires safety equipment, essential medicine and a first-aid kit, and states that a person who disobeys can face imprisonment which may extend to two years.

Now do the arithmetic on the Sar Pass profile. Grahan is around 7,700 ft. Min Thach is around 11,150 ft. Nagaru is around 12,470 ft. The pass is around 13,800 ft. From Day 2 onwards the entire trek sits inside the 9,000 to 15,000 ft band. On the plain reading of that order, DFO permission from the Parvati Forest Division is required.

The Tribune's own reporting noted that most trekkers do not take permission from the Forest Department or bother to inform the police. That is a description of practice, not a defence of it. If something goes wrong at Nagaru, the paperwork is what puts a rescue in motion.

Registered operators. Himachal regulates adventure operators under the Himachal Pradesh Miscellaneous Adventure Activities (Amendment) Rules, 2021, made under the HP Tourism Development and Registration Act, 2002. Operators must register with the Tourism Department and specify trekking as a registered specialisation. Operators, guides and associations based outside Himachal must maintain a local office in the state. Ask your operator for the registration number. A serious one will have it ready.

Fees. I could not find any published Himachal Forest Department fee schedule specific to the Sar Pass route, Grahan camping or the Parvati Division for this trail. Some operators list "forest permits and camping charges, if any" as an inclusion, which is a tell that the amount is variable and unpublished. Do not trust a specific rupee figure quoted on a blog. Carry cash and ask your operator to itemise what they are paying on your behalf.

Who runs it. The Youth Hostels Association of India runs Sar Pass as its National Himalayan Trekking cum Training Expedition, with 2026 reporting dates spanning 1 May to 31 May, in a 7-night, 8-day format. That is the cheapest organised way to do this trek and the reason so many college groups end up on it. Indiahikes documents Sar Pass but does not sell it. They list it in their DIY Trek Index as a trek you can do on your own, and their commercial URL redirects to the documentation page with no departure dates. Draw your own conclusion from that.

The Snow Slide: What It Actually Is

Beyond the pass, on the descent towards Biskeri Thach, there is a drop of roughly a hundred feet that in snow conditions is descended by sitting down and sliding. Indiahikes documents up to three successive slides, the first as far as a kilometre depending on snow conditions, the second longer, the third steeper.

Their own description: the slide is fun and, in their wording, "completely harmless as long as some precautions are taken." Those precautions, per the same source, are loose belongings including phones and goggles stowed inside the bag, legs kept tight together and not dug into the snow to slow down, and elbows kept firmly by the side of the trunk and pushed back into the snow to brake.

Two honest caveats. First, that phrasing is more relaxed than I would write it. A glissade on a slope you cannot see the bottom of, with rock under thin spring snow, is a real hazard and the technique matters. Second, no snow means no slide. The glissade only exists while the snow holds, roughly April to early June. Anyone selling you a September Sar Pass with a snow slide is selling you something that does not exist.

I found no documented fatality or serious injury attributable to the Sar Pass glissade in any credible source. That is not the same as a clean safety record, since Indian trekking incidents are under-reported, but it is what the record shows.

Accommodation

On the trail, tents. Nagaru and Min Thach have no permanent shelter. Grahan is a village with basic guesthouse rooms, and this is the only night of the trek where sleeping indoors is realistic. Biskeri Thach is a meadow.

In Kasol. The full spectrum, from Rs 400 dorm beds to riverside guesthouses. Book ahead in May, which is peak season, and expect Kasol to be crowded and noisy.

In Barshaini, Tosh, Kalga and Pulga. Guesthouses and homestays at the far end of the valley, useful if you want a night after finishing the trek rather than driving straight to Kasol. Barshaini is where the road ends and where the buses leave from.

On the sleeping bag question. Nagaru is the coldest night and it is exposed. If your operator supplies bags, ask for the temperature rating in writing. A summer bag at 3,800 m on a ridge in May is a miserable night.

Food on the Trail

Kasol has cafes serving everything from Israeli food to trout. Enjoy that on Day 0.

After that it is what your operator carries. Grahan has small shops with basic supplies and chai. Above Grahan, nothing. Min Thach, Nagaru and Biskeri Thach are camps with a kitchen tent, not villages with shops.

Carry your own dry fruit, electrolyte sachets and something salty. The Day 4 crossing is a long day starting in the dark and appetite drops at altitude, so calories you will actually eat matter more than calories you theoretically packed.

Water above Min Thach comes from snowmelt. Purify it. Carry at least two litres of capacity, and fill before the Nagaru climb because there is nothing reliable on the ridge.

Nearby Attractions

• Manikaran Sahib — the gurdwara and hot springs, about 4 km up-valley from Kasol. The springs are genuinely hot and the langar is open to all.
• Kheerganga — hot springs at the head of a different arm of the valley, reached from Barshaini. Read our Kheerganga trek guide before you plan it, because the rules there changed sharply in 2024.
• Tosh and Kalga — villages above Barshaini, both walkable and both good places to lose a day.
• Malana — an ancient village with its own customs and its own set of visitor sensitivities. Behave accordingly.

If you are stringing Himachal treks together, Hampta Pass is the natural pairing. It is a genuine crossover from Kullu green to Lahaul desert and it is a better trek than Sar Pass on most measures. Bhrigu Lake above Manali is the short option if you have only three days.

Budget Breakdown

Two people, seven days from Mumbai, doing it through an operator. Indicative, not quoted rates.

Item	Budget (₹)	Mid-range (₹)
Mumbai–Chandigarh return flight (per person)	7,000	11,000
Chandigarh–Bhuntar–Kasol return, bus or taxi (per person)	2,000	6,000
Trek package, 5 days, per person	8,000	14,000
Kasol stay, 2 nights (per room)	1,600	4,500
Food off-trek, per person	1,500	3,000
Gear rental, per person	1,000	2,500
Buffer	3,000	5,000

The YHAI programme sits well below the budget column on the trek component and is the cheapest legitimate route in. Forest and permit charges are not listed here because no official schedule is published for this route.

Practical Tips

Sleep a night in Kasol before Day 1. Non-negotiable if you have flown in from sea level.

Start Day 4 in the dark. Firm snow in the morning is safer and faster than slush at eleven.

Microspikes or crampons, and a trekking pole. In May the Nagaru climb and the pass approach are snow. Ordinary trail shoes on a hard snow slope are how people slide where they did not intend to. Our trekking footwear guide for Sahyadri terrain sets the baseline, but for this trek you want a stiffer sole and the ability to attach traction.

Gaiters. The snow is wet spring snow and it gets into everything.

Network drops above Grahan and does not come back until you are near Barshaini. Jio and Airtel work in patches in Kasol. Tell somebody your route and your expected exit date before you lose signal.

Cash. Kasol has ATMs that are frequently empty and the valley runs on cash above Kasol.

Sun. Snow reflects, and at 4,000 m in May the burn is fast. Sunglasses that actually block UV, not fashion sunglasses. Sunscreen on the underside of your nose and chin.

If this is your first Himalayan trek after a few Sahyadri seasons, read Sahyadri trek vs Himalayan trek first. The pacing is different and the mistake Maharashtra trekkers make is going hard on Day 1 and paying for it at Nagaru.

Safety Tips

Acute mountain sickness and acclimatisation. This is the part of Sar Pass that its beginner-friendly reputation obscures.

You go from Kasol at 1,700 m to Nagaru at 3,800 m in three days, and then to 4,220 m on the fourth. That is a fast profile. If you have flown into Bhuntar from Mumbai and started walking the next morning, you have gone from sea level to sleeping at 3,800 m in about four days.

What AMS looks like: a headache that does not respond to water or paracetamol, nausea, loss of appetite, breathlessness at rest, dizziness, and broken sleep. It typically appears six to twelve hours after gaining altitude, which on this trek means it hits you at Nagaru, at night, in a tent, on a ridge, in the cold.

What to do:

• Spend a night at Kasol before you start. Then walk the profile as given. Do not compress five days into four to save a day of leave.
• Three to four litres of water a day. Altitude dehydrates you faster than you notice.
• No alcohol at Nagaru or Min Thach. Kasol makes this harder than it sounds.
• Watch for HAPE and HACE signs: a wet cough, gurgling breath, confusion, staggering, inability to walk a straight line. These are descent-now emergencies, not wait-and-see ones.
• If a headache is not clearing, go down. Descent is the treatment. From Nagaru, dropping to Min Thach usually fixes it.
• Never leave an unwell person alone at Nagaru while the group goes for the pass. Read when to cancel or turn back from a trek before you are the one making that call at 4 am.

The Min Thach to Nagaru traverse. Steep fall to the valley, slippery, and the trail can vanish under snow. This is the section to rope up, slow down and stay in single file behind the guide.

Weather. Spring in the Parvati Valley means afternoon build-up and sudden whiteout on the ridge. Nagaru offers no shelter. If the weather turns while you are camped there, the correct answer is often to descend rather than wait it out.

The valley's record. The Parvati Valley has a documented pattern of people disappearing. ThePrint's July 2026 ground report cites a Tribune figure of 19 foreign nationals gone missing in Kullu district since 1991, most of them in the Parvati Valley, and police data showing 1,078 people reported missing in the valley between 2003 and 2023 with only 498 traced. There is no dedicated government rescue team in the valley; police hire local trek guides when a search is needed. A rescuer quoted in that report, Dhale Suman, said that many trekkers underestimate the mountains because the routes have become popular on social media.

That is the context you are walking into. It is not a reason to skip the trek. It is a reason to register, walk with a group, and not wander off the marked route.

Glacial lake risk. A C-DAC survey cited in the same report tracked Vasuki Lake, a glacial lake above Kheerganga, growing from 10.36 hectares in 2017 to 13.38 hectares in 2024, with outburst-flood risk downstream towards Kasol, Manikaran and Jari. Relevant if you are camping near the river at the valley floor.

Group discipline. Stay together on the Day 5 descent through forest, which is where groups string out and someone takes a wrong branch. Group trekking safety rules covers the basics.

Emergency numbers. 112. Note the Kullu DDMA number and your operator's slope contact before you lose signal above Grahan.

Common Mistakes

Believing the "easy beginner trek" framing without qualification. It is graded easy-moderate and the first two days are gentle. Day 3 and Day 4 are not, and the campsite at Nagaru is the coldest and most exposed night many first-timers will have had.

Skipping the acclimatisation night in Kasol. The most common and the most consequential error.

Going without registering. TMS registration is required in Kullu district and DFO permission is required for the altitude band this trek occupies. Rescue liability and, per the DC's order, imprisonment of up to two years are written into the framework.

Booking on Instagram. Ask for the Himachal Tourism Department registration under the 2021 adventure activity rules. If the operator cannot produce it, walk away.

Turning up in June expecting snow, or in October expecting the slide. The snow window is roughly April to early June. YHAI runs the whole 2026 programme inside May. That should tell you everything.

Wearing running shoes. On a spring snow slope this is not a minor comfort issue.

Treating Kasol nightlife as part of the acclimatisation plan. Alcohol at altitude, the night before you go up, is a genuinely bad idea.

Best Time to Visit

May — the season. This is the trek's window and there is not much argument about it. Snow on the Nagaru climb and over the pass, the Sar still frozen, the glissade working, and long daylight. YHAI's entire 2026 Sar Pass programme runs 1 to 31 May. Go in May.

April — early and colder. More snow, harder conditions, fewer people. Doable with the right operator and the right gear, not a first-timer's month.

June — the snow goes. Early June still has some. By late June the slide is gone and you are walking on rock and mud. The trek is still pretty. It is a different trek.

July to September — skip it. Monsoon in the Parvati Valley means landslides on the approach road, leeches in the forest, cloud on the ridge and nothing to see from the pass.

October to November — clear, cold, no snow slide. Post-monsoon air is the sharpest of the year and the meadows are gold. If you want views rather than snow, this is a real option. Nights at Nagaru get genuinely hard.

December to February — no. Indiahikes explicitly does not recommend the winter months because of heavy snow. The pass is not a winter objective for a trekking group.

FAQ

Q: Which state and district is the Sar Pass trek in? A: Kullu district, Himachal Pradesh, in the Parvati Valley. Wikipedia lists it under Kullu district with coordinates in the Parvati Valley. Any source placing Sar Pass in Kashmir is wrong.

Q: How high is Sar Pass? A: Wikipedia gives 4,220 m (13,850 ft). Indiahikes documents the high point as 4,200 m and elsewhere writes 13,799 feet. Use 4,220 m and treat the twenty-metre difference as survey variation.

Q: How long is the Sar Pass trek? A: Roughly 49 km across five trekking days, based on the stage distances Indiahikes publishes: 10 km, 7 km, 8 km, 14 km and 10 km. Add a day either side for travel.

Q: Is Sar Pass suitable for beginners? A: For fit beginners, yes, with two conditions. You need an acclimatisation night at Kasol, and you need to accept that Day 3 involves a steep, exposed traverse and Day 4 is a snow crossing at over 4,000 m starting before dawn. Indiahikes grades it easy-moderate for fit beginners. It is not a walk-up.

Q: Do I need a permit for the Sar Pass trek? A: Yes, in effect two things. Registration on the Himachal Trekking Management System portal at trekking.hp.gov.in is required for trekking in Kullu district. Separately, a Kullu DC order of September 2022 requires Divisional Forest Officer permission for trekking between 9,000 and 15,000 feet, and the Sar Pass route sits inside that band from Day 2 onwards. Confirm the current position with the Parvati Forest Division before you travel.

Q: What is the Sar Pass entry fee? A: No official fee schedule for this route is published by the Himachal Forest Department that I could locate. Operators list forest and camping charges as variable. Anyone quoting you a precise figure is guessing.

Q: Is the snow slide safe? A: Indiahikes describes it as harmless with precautions, specifically stowing loose items, keeping legs together and braking with elbows in the snow. It is a glissade on a snow slope, so it is only as safe as the conditions and the technique. It also only exists while the snow is there, roughly April to early June.

Q: How do I get from Mumbai to Kasol without going through Delhi? A: Fly Mumbai to Chandigarh direct, then take a Volvo bus or taxi to Bhuntar and on to Kasol. Bhuntar has flights but they route via Delhi and the airport is weather-sensitive.

Q: Where does the trek finish and how do I get back? A: At Barshaini, the last motorable village in the Parvati Valley, reached from Biskeri Thach through Pulga and Tulga. Buses and taxis run from Barshaini down to Kasol and Bhuntar.

Conclusion

Sar Pass is worth doing, and it is worth doing honestly. It gives a fit first-timer a real Himalayan pass, a night on an exposed ridge, a frozen lake at 4,000 m and a descent on snow that is genuinely good fun. Five days, one valley, one crossing.

What it is not is a casual add-on to a Kasol holiday. The Kullu district administration has built a permit regime around exactly the kind of unregistered walking that this valley used to be famous for, and the valley's missing-persons record is not folklore, it is police data. Register on the TMS portal. Get the DFO position clarified. Use an operator with a Himachal Tourism registration number they will actually show you.

Go in May. Sleep a night in Kasol first. Start Day 4 before dawn.
