Kunzum Pass is not guaranteed to be open in May. That is the most important thing to know before you build any trip around it.
At 4,551 metres (14,931 feet), Kunzum Pass connects Lahaul (coming from Manali via the Atal Tunnel and Batal) with the Spiti Valley side (Kaza and beyond). Every winter, it gets buried under 10 to 20 feet of snow. BRO (Border Roads Organisation) begins clearance work each spring, and how quickly they finish depends entirely on how much snow fell and how the weather behaves in April and early May.
In some years, the pass becomes crossable by the last week of May. In other years, it stays closed well into June. There is no fixed date. If your Spiti trip in May 2026 depends on Kunzum being open, you need to plan with flexibility, not certainty.
We have been running Manali-based Spiti trips for over a decade, and every May we get calls from travellers whose plans just collapsed because they treated May as a guaranteed travel window. This guide is the honest version of what May at Kunzum actually involves.
Quick Answer Snapshot
Is Kunzum Pass open in May 2026?
Not confirmed. Late May has better odds than early May, but nothing is certain until BRO completes clearance.
Likely opening window
Historically, Kunzum opens anywhere between mid-May and mid-June. The timing shifts every year.
Altitude
4,551 metres (14,931 feet).
Is early May practical?
Usually not. The pass is typically still snow-covered or under active clearance in the first two weeks.
Is late May likely to work?
Possible in some years. Check BRO updates and local reports before committing.
Is Chandratal accessible via Kunzum in May?
Unlikely for most of May. Chandratal road access consistently lags behind the Kunzum opening.
Who should postpone to June
Families, first-time Spiti travellers, anyone with non-refundable fixed-date bookings, and those uncomfortable with last-minute plan changes.
Who may still enjoy May
Flexible travellers, snow photography enthusiasts, experienced bikers, and anyone willing to work around road uncertainty.
Is Kunzum Pass Open in May 2026?
As of now, there is no confirmed opening date for Kunzum Pass in May 2026. This is entirely normal — the opening depends on BRO snow clearance, which starts in spring and progresses based on that winter’s snowfall and current weather conditions.
Whether Kunzum Pass is open in May 2026 on your specific travel date will only become clear in the days immediately before. In past years, the pass has opened as early as mid-May and as late as the second week of June. There is no pattern reliable enough to plan around with confidence.
May is a transition month at Kunzum. The pass is caught between winter closure and summer access. If your entire trip depends on crossing Kunzum, May carries real risk. If you have the flexibility to adjust dates or switch to the Shimla-side entry, May can work — but only with proper backup planning.
Why May Is Unpredictable at Kunzum Pass
Understanding why May is uncertain helps you plan smarter instead of just hoping for the best.
Winter snowpack
Kunzum sits above 4,500 metres. Months of accumulated snow does not vanish overnight. Even when the sun is strong in May, snow walls of 10 to 20 feet along the road are common. Clearance requires heavy machinery, not just sunshine.
BRO clearance pace
BRO works from both sides — Kaza and Manali — clearing toward the middle. Progress depends on snowfall quantity, machine availability, and weather windows. A fresh snowfall in late April or early May can set back clearance by a week or more.
Late snowfall risk
May snowfall at Kunzum is not unusual. Even if the road has been partially cleared, a fresh dump can close it again for several days.
Road damage after thaw
When snow melts, it reveals broken road edges, washed-out patches, and loose gravel underneath. A road being technically open does not mean it is smooth or safe for all vehicles.
Wind and visibility
High winds at the pass can reduce visibility and make driving uncomfortable, especially in exposed stretches near the top. A clear morning can turn into a whiteout by noon.
Early May vs Late May: The Difference Is Enormous
Early May (1–10 May)
In most years, early May is too soon for Kunzum. The pass is typically still under snow with clearance work ongoing. Some years the Kaza-side approach becomes possible toward the end of this window, but a full Manali-to-Kaza crossing through Kunzum is rarely viable in the first 10 days of May.
Planning a trip that requires crossing the pass in early May is not recommended unless your schedule is completely flexible and you are genuinely comfortable with the trip not happening.
Mid-May (11–20 May)
This is the hopeful window. In years with lighter snowfall, the pass starts becoming accessible around mid-May. But it is far from guaranteed. Even when open, road quality is poor — slushy patches, narrow clearance between snow walls, and unstable edges are standard.
If you are travelling mid-May, keep your itinerary loose enough to absorb a day or two of waiting without the entire plan falling apart.
Late May (21–31 May)
Late May has the best odds of the month. In several recent years — including 2025 (24 May opening for 4×4 vehicles) and 2022 (3 May, unusually early) — the pass has been open by the last week. But there are also years where it stayed closed until the first week of June.
If you can plan for late May and have the ability to extend by a couple of days if needed, your chances are reasonable. Fixed, non-refundable plans in late May still carry some risk.
Kunzum Pass Road Status in May: Kaza Side vs Manali Side
The Kunzum Pass road status in May is very different depending on which direction you approach from. Understanding this distinction is essential for planning.
Kaza Side (Kaza → Losar → Kunzum)
The road from Kaza to Kunzum Pass is roughly 80 km via Losar. This side tends to become approachable earlier than the full Manali route because it is a shorter climb and does not depend on the notoriously difficult Gramphu-to-Batal section being clear.
In some years, day trips from Kaza to Kunzum become possible by mid-to-late May, even before the full crossing is officially declared open. You drive up from Kaza, experience the snow and the views at the top, and return the same day. This is often the most realistic way to experience Kunzum Pass in May.
If you are already in Spiti via the Shimla-Kinnaur route, the Kaza approach to Kunzum may be feasible even when the Manali route is still blocked.
Manali to Kunzum Pass in May: The Full Crossing
The complete Manali-to-Kaza route via Atal Tunnel, Gramphu, Batal, and Kunzum depends on the entire chain being clear. Even if Kunzum Pass itself is open, the Gramphu-to-Batal section must also be passable — and this stretch has its own clearance challenges, including water crossings, broken road patches, and avalanche-prone zones.
A full Manali to Kunzum Pass crossing in May is significantly less likely than a Kaza-side day visit. If this crossing is central to your plan, be prepared for the real possibility that it will not work, and have the Shimla-side entry as your backup route into Spiti.
Can You Cross Manali to Kaza via Kunzum in May 2026?
Maybe. But it depends entirely on timing and conditions, and there is no way to guarantee it before the season unfolds.
Best-case scenario
BRO clears the route efficiently, weather cooperates, and the Manali-to-Kaza road opens by the last week of May. This has happened in some years — it is possible.
Realistic scenario
The route opens partially, with rough patches, slushy stretches, and uncertain daily conditions. Vehicles with high ground clearance and experienced drivers make it through. Others get stuck or turn back.
Why fixed travel dates are risky
If you have booked non-refundable transport or stays for a specific May date, you are gambling on the road being open exactly when you need it. There is no refund for snow.
The Shimla-side alternative
If your primary goal is to reach Spiti in May, the Shimla-to-Kaza route via Kinnaur is far more reliable. This route stays at lower altitudes for longer and does not depend on Kunzum being open. Many experienced Spiti travellers use the Shimla side in May and treat Kunzum as an optional day trip from Kaza if conditions allow.
Chandratal via Kunzum Pass in May 2026: Is It Possible?
Unlikely for most of the month, and possibly not even by the end.
Reaching Chandratal via Kunzum in May is a separate question from whether Kunzum itself is crossable. Even when the pass becomes open for vehicles, the 14 km side road branching off toward Chandratal Lake may still be blocked, uncleared, or too rough to drive. Camp operators near the lake typically do not set up until the diversion road is properly passable, which usually means mid-June or later.
If you are planning a May trip specifically to see Chandratal, set expectations carefully. In most years, reliable Chandratal access does not begin until June. A late May visit to Kunzum top is realistic in a good year. A Chandratal visit through Kunzum in May is far less likely.
If Chandratal is your main goal, June is the safer month to build your trip around. We cover this in detail in our Chandratal road status guide.

Kunzum Pass Weather in May 2026: What to Expect
The Kunzum Pass weather in May is serious mountain weather — not the pleasant spring conditions most plains travellers imagine. Even on days when the road is technically open, conditions at 4,551 metres demand respect.
Morning temperatures
Expect minus 5°C to plus 5°C at the pass itself, sometimes colder with wind chill. By afternoon, direct sunshine can make it feel warmer, but temperatures drop sharply again after sunset.
Snow is the dominant feature
Snow walls line the road where BRO has cut through. The ground near the pass is a mix of compacted snow, slush, mud, and loose gravel. Walking at the top is possible but slippery.
Wind is constant and biting
It compounds the cold and makes standing at the top uncomfortable after a few minutes. Clear-sky days look rewarding in photos, but the wind does not stop just because the sun is out.
Visibility can vanish suddenly
If clouds roll in, driving on a rough road at this altitude in low visibility is genuinely dangerous. If weather turns while you are near the pass, it is always safer to wait or turn back than to push through.
Kunzum Pass Snow in May: What the Landscape Looks Like
If you do reach Kunzum in May, the landscape is nothing like the summer version. The Kunzum Pass snow in May transforms the entire area into a white, dramatic world that most travellers never get to see.
Towering snow walls run along both sides of the road, sometimes higher than your vehicle. The barren brown mountains of summer are buried under thick snowpack, and the sheer scale of it is striking. The Kunzum Devi Temple at the top is likely still surrounded by snow. Travellers who make it up leave prayer flags and circle the temple, continuing a tradition that predates the road itself.
On clear days, the valley views are spectacular — Spiti Valley dropping away on one side, the Chandra range rising on the other. The snow softens every sharp edge of the terrain and creates a silence that is hard to find anywhere else.
The road surface at the top, however, is rough. Patches of ice, slush, and mud are normal. Walking around takes effort because of both altitude and terrain. Spend time taking it in, but get back in the vehicle before the cold catches up with you.
Kunzum Pass in May: Is It Worth It? (By Traveller Type)
Photographers and Snow Enthusiasts
If you love dramatic mountain landscapes, snow-covered passes, and empty roads, May at Kunzum can be extraordinary. The light is sharp, the snow is thick, and you will have the pass to yourself most days. But reaching it is not guaranteed — treat Kunzum as a bonus, not the purpose of the trip.
Motorcycle Riders
Riding to Kunzum in May is for experienced mountain riders only. Road conditions are rough, slippery, and cold. If you have handled ice patches, gravel, and high-altitude riding before, it can be an incredible experience. If you are new to Himalayan biking, June or July is the time to start.
Self-Drive Groups
SUVs with high ground clearance and confident, experienced drivers can make it in late May during a good year. Sedans and low-clearance cars should not attempt it under any circumstances. The reward is an uncrowded, snow-draped pass that summer tourists never see — but the risk of getting stuck is very real.
Families with Children
May is not recommended for families, particularly with young children or elderly members. The altitude, extreme cold, uncertain road conditions, and minimal facilities along the route combine to make it a stressful experience. June or later is a significantly better choice for family travel.
First-Time Spiti Travellers
If this is your first Spiti trip, May adds too much uncertainty to what should be a memorable, enjoyable experience. You may spend days waiting for a road to open instead of actually exploring the valley. Plan for June or later, when routes are reliable and the experience is predictable.
Essential Packing List for Kunzum Pass in May
Conditions at 4,551 metres in May are cold, windy, and unpredictable. Pack for winter, not spring.
Warm clothing
Thermal base layers (top and bottom), a proper insulated down or puffer jacket, a windproof outer shell, warm gloves, a woollen cap or beanie that covers ears, and thick warm socks. Multiple layers work better than one heavy jacket.
Eye and skin protection
Sunglasses with UV protection are essential — snow glare at altitude is intense. Sunscreen with high SPF, because UV radiation at 4,500 metres is severe even when the air feels cold.
Sturdy footwear
Waterproof boots or shoes with good grip. The ground near the pass is a mix of ice, slush, and loose stone. Regular sneakers are inadequate.
Food and water
Dry fruits, biscuits, energy bars, and a water bottle. There are no shops at the pass and extremely limited options along the approach road.
Cash
Carry ₹2,000 to ₹4,000 in small denominations. No ATMs exist between Kaza and the pass, and digital payments do not work without mobile network.
Offline maps
Download the area on Google Maps or similar apps before leaving Manali or Kaza. Network coverage disappears well before you reach the pass.
Medicines
Paracetamol, ORS sachets, and Diamox for altitude sickness (consult your doctor before carrying). A basic first-aid kit.
Power bank
Fully charged. Cold weather drains phone batteries fast, and there is no charging anywhere near the pass.
Safety and Acclimatisation at Kunzum Pass in May
Kunzum at 4,551 metres is serious altitude, and in May the conditions compound the physical demands significantly.
Acute Mountain Sickness (AMS) is a genuine concern, especially if you have driven up rapidly from lower altitudes. Symptoms include persistent headache, nausea, dizziness, and unusual fatigue. The risk increases sharply when you gain altitude quickly without giving your body time to adjust.
From the Kaza side
You are already at around 3,800 metres, which gives your body a better starting point. Spending a day or two in Kaza before driving up to the pass makes a measurable difference.
From the Manali side
The altitude gain is faster and more taxing. Manali sits at 2,050 metres — crossing Kunzum the next day puts you at 4,551 metres with barely 24 hours of adjustment. A halt at Sissu (3,100 metres) or Keylong helps ease the transition.
Children and elderly travellers
need extra caution. The combination of altitude, cold, and rough road hits them harder. If anyone in your group shows persistent headache, nausea, or confusion, descend immediately. Do not wait at altitude hoping symptoms will pass on their own.
An open road does not mean an easy trip. Even when you can technically drive to Kunzum in May, the conditions test both the vehicle and the people inside it. Go prepared, drive slowly, and respect the mountain.
How to Check Kunzum Pass Road Status Before You Travel
This is the single most important step in planning Kunzum Pass in May. Do not rely on a blog post, a social media update from last year, or anyone’s prediction. The only reliable information is recent, local, and confirmed close to your travel date.
Official Lahaul & Spiti district road-status page
hplahaulspiti.nic.in/road-status — the primary authoritative source during clearance season.
BRO updates
Border Roads Organisation occasionally shares clearance progress on official channels. These are the most official source, though not always timely.
Local contacts
Hotel owners in Kaza and Manali, taxi drivers, and travel operators who run regular Spiti trips have the most current ground-level intelligence. They know which sections are clear, which are under work, and what vehicles are getting through.
Travel community groups
Spiti-focused Facebook and WhatsApp groups share real-time road reports from travellers already on the route. Always cross-check multiple sources.
Our team
If you book through us, our team tracks road conditions daily during the opening season and adjusts trip plans accordingly. This is one of the practical advantages of booking with a local operator.
Common Mistakes Travellers Make with Kunzum Pass in May
Assuming May means open season
May is a transition month, not the start of summer at 4,500 metres. The pass may not be open at all during the first half of the month.
Confusing Kaza-side access with a full Manali crossing
Reaching Kunzum top from Kaza for a day visit is very different from completing a full Manali-to-Kaza crossing. One can be possible while the other is not.
Assuming Chandratal will be accessible
Kunzum opening does not automatically mean Chandratal is reachable. The diversion road, camp availability, and lake-area conditions are separate factors entirely.
Packing light clothing because it is “summer.”
May on a calendar does not translate to May conditions at 4,500 metres. Sub-zero temperatures, wind chill, and snow are normal.
Booking non-refundable tickets and stays
Fixed bookings for May that depend on Kunzum being open are a gamble. If the road is closed on your date, you lose money. Book with cancellation flexibility wherever possible.
Underestimating altitude fatigue
Driving to 4,551 metres on a rough road in cold conditions takes more out of your body than you expect. Plan generous rest stops and keep your daily schedule light.
Not building in buffer days
A single day of snowfall can close the pass for two to three days. If your trip has zero flexibility, one weather event ruins everything.
Final Verdict: Should You Plan Kunzum Pass in May 2026?
Kunzum Pass in May 2026 is not a sure thing. It is a possibility that depends on snowfall, clearance speed, and weather — none of which can be predicted months in advance.
Early May is almost certainly too early for a crossing. Mid-May is hopeful but uncertain. Late May has the best odds, but even then it is not guaranteed.
The Kaza-side approach is more realistic in May than a full Manali-to-Kaza crossing. Chandratal access through Kunzum should not be expected in May.
If you want snow-covered passes, empty roads, and a raw mountain experience — and you are genuinely willing to be flexible — May can deliver something deeply rewarding. If you need certainty, comfortable roads, and a predictable itinerary, June is the smarter choice.
The best May strategy is to enter Spiti from the Shimla-Kinnaur side, base yourself in Kaza, and treat Kunzum as an optional day-trip opportunity if conditions allow. That way, your trip does not live or die on a single pass being open.
Plan Your Spiti Trip Around Kunzum Pass
At Manali Tour Planner, we build Spiti itineraries around actual ground conditions — not assumptions about what should be open. Whether you want a Shimla-entry loop with a Kunzum day trip, or a late-May Manali-to-Kaza attempt with proper backup routing, we plan for what the mountains are actually doing.

अक्सर पूछे जाने वाले प्रश्न
Is Kunzum Pass open in May 2026?
There is no confirmed opening date yet. Kunzum Pass typically opens between mid-May and mid-June, depending on snow clearance progress. Late May has better odds than early May, but nothing is certain until BRO finishes the work. Always verify the latest road status before travelling.
When is Kunzum Pass expected to open in 2026?
Based on historical patterns — including the 24 May 2025 opening and the unusually early 3 May 2022 opening — Kunzum may open between the third week of May and the first or second week of June 2026. The exact date depends on winter snowfall levels and spring clearance pace.
Can I cross from Manali to Kaza via Kunzum in May?
Possibly in late May if conditions are favourable, but the full Manali-to-Kaza crossing via Kunzum is not reliable in May. It depends on the entire route chain being clear, including the notoriously difficult Gramphu-to-Batal section. Have the Shimla-side entry as your backup.
Is late May a good time to visit Kunzum Pass?
Late May offers the best chance within the month. In years with moderate snowfall, the pass becomes accessible by the last week. However, road conditions remain rough, cold, and require high-clearance vehicles. Fixed-date plans still carry some risk.
Can I visit Chandratal through Kunzum in May 2026?
Unlikely. Even when Kunzum opens, the 14 km side road to Chandratal, camp setup, and lake-area access consistently lag behind. Chandratal typically becomes reliably accessible from mid-June onward. If the lake is your main goal, plan for June.
Which side of Kunzum Pass is easier to access in May?
The Kaza side. The road from Kaza to Kunzum top is shorter (roughly 80 km via Losar) and often clears earlier. A day trip from Kaza to the pass can be possible in late May even when the full Manali crossing is not.
How much snow is there at Kunzum Pass in May?
Significant. Snow walls of 10 to 20 feet line both sides of the road where BRO has cut through. The ground near the top is a mix of compacted snow, slush, and gravel. The pass looks and feels like deep winter, not spring.
What is the weather at Kunzum Pass in May?
Expect morning temperatures of minus 5°C to plus 5°C, strong biting winds, and possible sudden drops in visibility if clouds roll in. Afternoons with direct sun feel warmer but nights are freezing. Pack full winter gear, not spring clothing.
Is a sedan safe at Kunzum Pass in May?
No. Only SUVs or vehicles with high ground clearance driven by experienced mountain drivers should attempt it. The road surface includes ice, slush, narrow clearance between snow walls, and unstable edges. Sedans risk underbody damage and getting stuck.
Is Kunzum Pass worth visiting in May for the snow?
If you love dramatic, snow-heavy mountain landscapes and are comfortable with uncertainty, absolutely. Kunzum in May offers a raw, uncrowded experience that summer visitors never get to see. But access is not guaranteed — treat it as a bonus, not a certainty.
Is there mobile network near Kunzum Pass?
No reliable network. Coverage drops out well before the pass from both sides. BSNL postpaid may work intermittently near Losar, but do not count on any connectivity at or near the pass. Download offline maps and inform someone of your route before setting out.
Where should I stop if weather changes near the pass?
From the Kaza side, fall back to Losar — the nearest settlement with homestays and food. From the Manali side, Batal (if operational in late May) or Sissu/Keylong are your realistic halt points. In bad weather, never push forward. Wait or descend.
Can families visit Kunzum Pass in May?
Not recommended, especially with young children or elderly members. The altitude, cold, rough roads, and uncertain access make it genuinely stressful. June or later is a much better choice for family trips to Spiti.
What is the safest backup plan if Kunzum is closed in May?
Enter Spiti from the Shimla-Kinnaur side. This route does not depend on Kunzum being open and is typically reliable in May. You can explore the entire Spiti Valley from Kaza and treat Kunzum as an optional day trip if conditions improve later during your stay.
