The Sar Pass trek is one of the Parvati Valley’s most popular spring outings: a five-day loop from Kasol that climbs through pine forest and shepherd meadows to a snow pass at about 4,220 metres (13,850 feet), then drops down a long snow slide that trekkers still talk about years later. It sits in Kullu district of Himachal Pradesh, and because it starts low and gains height steadily, it draws a lot of first-time Himalayan trekkers each April, May and June.
Sar Pass is a moderate 5-day, roughly 48 km trek in the Parvati Valley of Himachal Pradesh, starting at Kasol (about 1,640 m) and topping out near 4,220 m. The best window is April to June, before the monsoon closes the ridges.
About the trek and quick facts
Sar takes its name from the local word for a lake; trekkers pass a small, usually frozen tarn on the way to the pass. The trail links the forest village of Grahan with the high meadows of Min Thach and Nagaru before crossing the pass and descending toward the Barshaini side of the valley. According to Wikipedia’s overview, which cites regional press and trekking accounts, the pass lies at about 4,220 m (13,850 ft) in the Parvati Valley of Kullu district; a few operators quote 4,223 m.
What makes it a good starter climb is the shape of the ascent. You begin in warm forest, gain height over three days, and only meet real snow near the top. The descent from the pass is often a seated glissade down a snow field, guided by your team.

|---|---|
| Base town | Kasol (about 1,640 m) |
| Highest point | Sar Pass, about 4,220 m (13,850 ft) |
| Total distance | About 48 km (operators list 48–50 km) |
| Duration | Typically 5 days from Kasol |
| Grade | Moderate; suitable for fit first-timers |
| Season | April to June |
Best time for the Sar Pass trek
The trek runs in spring and early summer. Snow lingers near the pass through May, which is exactly why people come: the crossing and the slide down are on snow. By late June the lower forest turns humid and the monsoon starts to build.
Avoid July, August and early September. Guides across the valley agree that the ridges and forest slopes become unstable in heavy rain, and the trek is generally not run then. Winter locks the upper camps in deep snow.
| Period | Conditions | Verdict |
|---|---|---|
| April | Cold nights, plenty of snow up high, quieter trail | Good, come prepared for cold |
| Mid-May to mid-June | Stable weather, snow at the pass, longest days | Best window |
| Late June | Warmer, humid forest, pre-monsoon showers | Fair, watch the forecast |
| July–early September | Monsoon; unstable slopes, leeches, landslides | Avoid |
| October–March | Heavy snow, camps closed | Not a trekking season here |
How to reach Kasol, the base
Everything starts at Kasol on the Bhuntar–Manikaran road. Most trekkers reach it by an overnight bus from Delhi or Chandigarh to Bhuntar, then a shared cab or bus up the Parvati Valley.
- By air: Bhuntar (Kullu–Manali) airport, code KUU, is the nearest, about 30 km from Kasol. Flights are few and often cancelled or delayed, so most people treat Chandigarh or Delhi as the practical air gateway and continue by road.
- By train: Chandigarh is the usual broad-gauge railhead, roughly 290–300 km away, connected to Delhi and other cities; from there it is about 8–9 hours by bus or cab. The narrow-gauge Joginder Nagar station is closer at around 144 km but poorly connected for onward travel.
- By road: Regular Himachal and Volvo buses run Delhi–Bhuntar overnight. From Bhuntar it is about 30 km (roughly an hour) to Kasol via the Bhuntar bridge and Jari.
| From | Distance to Kasol | Typical road time |
|---|---|---|
| Bhuntar airport (KUU) | ~30 km | ~1 hour |
| Kullu town | ~40 km | ~2 hours |
| Chandigarh railhead | ~290–300 km | ~8–9 hours |
| Delhi | ~500+ km | ~12–14 hours (overnight bus) |
The route, day by day
The standard itinerary is five days from Kasol, with a rest and acclimatisation buffer built into the middle. Distances and camp altitudes below follow common operator itineraries and should be treated as planning figures; your team may adjust camps with the snow line.
- Day 1 — Kasol to Grahan village (about 9 km): A forest walk beside the Grahan nala to the old village. Gentle to moderate; a good first day to find your rhythm.
- Day 2 — Grahan to Min Thach (about 7.5 km, camp near 3,400 m / ~11,150 ft): A steady climb out of the trees into your first meadow, with valley views opening up.
- Day 3 — Min Thach to Nagaru (about 5 km, camp near 3,780 m / ~12,400 ft): Short but steep, gaining the ridge below the pass. This is the acclimatisation-critical night.
- Day 4 — Nagaru to Sar Pass, then down to Biskeri Thach (about 12 km): An early start on snow to the pass at about 4,220 m, then the long snow-slide descent to the Biskeri meadow. The biggest day.
- Day 5 — Biskeri Thach to Barshaini, drive to Kasol: A descent through forest and villages to the roadhead at Barshaini or Pulga, then a short drive back.
| Day | Stage | Distance | Camp altitude |
|---|---|---|---|
| 1 | Kasol → Grahan | ~9 km | ~2,350 m |
| 2 | Grahan → Min Thach | ~7.5 km | ~3,400 m |
| 3 | Min Thach → Nagaru | ~5 km | ~3,780 m |
| 4 | Nagaru → Sar Pass → Biskeri Thach | ~12 km | pass ~4,220 m |
| 5 | Biskeri Thach → Barshaini → Kasol | ~10 km + drive | roadhead ~2,400 m |
Difficulty, altitude and AMS
Sar Pass is graded moderate. The distances are manageable, but Day 4 is long, cold and on snow, and you sleep above 3,700 m at Nagaru. Basic fitness matters: build up to a comfortable 5 km run or a long daily walk in the weeks before.
The real risk is acute mountain sickness (AMS). According to the CDC Yellow Book (2026 edition), AMS is common above 2,500 m and usually begins within hours of ascent, with headache plus loss of appetite, nausea, disturbed sleep, fatigue or dizziness. The CDC advises gradual or staged ascent and, where possible, acclimatising for 2–3 nights around 2,450–2,750 m before going higher.
Two severe forms can follow. The CDC notes that ataxia (loss of coordination) and confusion are warning signs of high-altitude cerebral edema (HACE), and breathlessness at rest signals life-threatening high-altitude pulmonary edema (HAPE). The rule is simple: if symptoms worsen, do not go higher, and descend. Tell your guide early; do not push through a bad headache to reach the pass.
Permits and forest rules
Sar Pass does not sit inside a national park, so it needs no Inner Line or park-entry permit. Moderate Parvati Valley treks such as Grahan are generally walked without a permit, though the Himachal Pradesh Forest Department can require registration or a camping fee on forest land, so most trekkers go through a registered operator who handles paperwork and a photo-ID check.
Himachal Tourism runs an online trekking registration portal (trekking.hp.gov.in) and recommends going with operators who provide guides, equipment and maps. Note also that the Forest Department has tightened rules elsewhere in the valley — for example, overnight camping at nearby Kheerganga was banned in 2024 — so confirm the current position for your dates. Carry out all waste; single-use plastic is restricted across Himachal.
What it costs
Most people join a fixed-departure group. Operator prices for the 5-day trek from Kasol are indicative planning estimates only and change by season and inclusions — reconfirm before booking. The figures below assume a standard package plus your own travel to Kasol.
| Item | Indicative cost | Notes |
|---|---|---|
| Guided trek package (Kasol to Kasol) | ₹8,000–₹13,000 | Tents, meals on trek, guide, permits; varies by operator |
| Delhi–Bhuntar bus (return) | ₹1,600–₹3,500 | Ordinary to Volvo; higher in peak season |
| Pre/post night in Kasol | ₹600–₹2,500 per night | Hostel dorm to mid-range room |
| Gear rental, tips, extras | ₹1,000–₹2,500 | Poles, gaiters, buffer |
Booking a package independently and carrying your own gear is cheaper; a fully supported private trip costs more. Keep some cash for the buffer, as card and UPI coverage thins out above Kasol.
Where to stay near the trailhead
You will usually spend a night in Kasol before the trek and one after. Kasol and the nearby villages of Chalal and Tosh have a wide spread of stays; book ahead for May and June weekends, when the valley is busy.
- Budget (₹500–₹1,200 per night): Backpacker hostels and dorms in Kasol and Chalal, plus simple guesthouses. Best value for solo trekkers.
- Mid-range (₹1,500–₹3,500 per night): Riverside guesthouses and small hotels with hot water and Wi-Fi in central Kasol.
- Higher-end (₹4,000+ per night): A handful of boutique riverside properties and cottages.
Rates are indicative for September 2026 and rise sharply on peak weekends. On the trek itself you sleep in the operator’s tents at Grahan, Min Thach, Nagaru and Biskeri.
Food on and around the trek
On the trail your team cooks simple, warming meals — dal (lentils), rice, roti, and plenty of hot drinks to keep fluids up at altitude. In Kasol the cafe scene is broad, from Israeli plates to local Himachali fare.
- Siddu (a steamed stuffed wheat bun, served with ghee or dal) — a Kullu-valley staple worth trying in Kasol.
- Trout — farmed in the valley and served grilled or fried at riverside cafes.
- Rajma-chawal (kidney beans with rice) — reliable, filling fuel before and after the trek.
Packing and practical tips
This is a cold, snow-touched spring trek, so pack for winter conditions up high even when Kasol is warm.
- Layers: thermals, a fleece, a down or synthetic insulated jacket, and a waterproof shell. Warm hat, sun hat, gloves.
- Feet: broken-in waterproof trekking boots plus gaiters for snow; two or three pairs of wool socks.
- Snow and sun: UV sunglasses (snow glare is intense), high-SPF sunscreen, lip balm, and trekking poles.
- Health: a personal first-aid kit, any regular medicines, and rehydration salts. Discuss AMS and acetazolamide with your doctor before you travel.
- Money and network: draw cash in Bhuntar or Kasol — ATMs are limited and UPI is patchy on the trail. Mobile signal fades above Kasol; there is none at the high camps.
- Medical help: the nearest hospitals are in Kullu; Kasol has only basic clinics, so a serious problem means descending and driving out.
- Solo women: Kasol is a well-travelled backpacker hub and organised group treks are a comfortable way to go; as anywhere, keep to daylight for transfers and share your plan.
A note on Parvati Valley safety
The Parvati Valley is beautiful and busy, but it has a documented history of trekkers going missing, often on unmarked solo routes or under the influence of local cannabis. The practical takeaways are factual and simple: do not trek off-route alone, stay with your group and guide, tell someone your plan, and treat river crossings and cliff edges with respect. Drug use is illegal and adds real risk in remote terrain.
For wider trip planning, our Kasol and Parvati Valley guide covers the towns and getting around, and the gentler Kheerganga trek guide is a good shorter alternative if Sar Pass feels like too much for now.
Nearby places
If you have days to spare around the trek, the valley and wider Kullu district reward a slower loop.

|---|---|---|
| Manikaran | ~4 km | Hot springs and a gurudwara-temple complex |
| Tosh | ~20 km (+ short walk) | Village views at the head of the valley |
| Kheerganga | Trek from Barshaini | Hot spring day-trek — see our Kheerganga trek guide |
| Manali | ~75 km | Hill-town base; see our Himachal hill stations guide |
Frequently asked questions
How high is Sar Pass and how hard is the trek?
Sar Pass reaches about 4,220 m (13,850 ft) in the Parvati Valley of Himachal Pradesh. The trek is graded moderate: distances are manageable and it suits fit first-timers, but the summit day is long and cold on snow, and you sleep above 3,700 m, so basic fitness and acclimatisation matter.
What is the best time to do the Sar Pass trek?
The best time is April to June, with mid-May to mid-June the most reliable window. Snow still lies near the pass then, which is part of the appeal, and the weather is relatively stable. Avoid July to early September, when the monsoon makes the forest slopes and ridges unstable.
How do I reach the Sar Pass trek base at Kasol?
Reach Kasol via Bhuntar, about 30 km away. Most trekkers take an overnight bus from Delhi or Chandigarh to Bhuntar, then a bus or shared cab up the Parvati Valley. Bhuntar airport has few flights; Chandigarh, roughly 290–300 km away, is the practical railhead, about 8–9 hours by road.
Do I need a permit for the Sar Pass trek?
No Inner Line or national-park permit is needed, as the route is outside protected parks. The Himachal Forest Department may require registration or a camping fee on forest land, so most trekkers use a registered operator who handles paperwork and ID checks. Himachal Tourism also runs an online trekking registration portal.
Is the Sar Pass trek safe for beginners?
Yes, for reasonably fit beginners who go with a guided group and acclimatise properly. The main hazards are altitude sickness above 2,500 m and the cold snow summit day. Descend if symptoms worsen, stay on-route with your team, and do not attempt the pass solo or in bad weather.
How much does the Sar Pass trek cost?
Guided 5-day packages from Kasol are commonly quoted around ₹8,000–₹13,000 per person, covering tents, meals on the trek, a guide and permits. These are indicative planning estimates that vary by operator and season; add your travel to Kasol, a night or two of accommodation, and gear. Reconfirm current prices before booking.
