Kunzum Pass is not guaranteed to be open in May. That is the honest starting point, and the most important thing to know before you build any plan around it.
At 4,551 metres, Kunzum Pass connects the Lahaul side (coming from Manali via Atal Tunnel and Batal) with the Spiti Valley side (Kaza and beyond). In winter, it is buried under snow. The clearance work starts in spring, and how fast it progresses depends entirely on how much snow fell that winter 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 shut well into June. There is no fixed date. If you are planning a Spiti trip in May 2026 that depends on Kunzum being open, you need to plan with flexibility, not certainty.
This guide covers what to realistically expect at Kunzum Pass in May 2026, how to plan around the uncertainty, and how to decide whether May is the right month for you or whether waiting until June makes more sense.
Quick answer snapshot
Current planning reality for May 2026
Kunzum Pass may or may not be fully open during May. Late May has better odds than early May, but nothing is confirmed until BRO completes snow clearance.
Likely opening window
Historically, Kunzum opens anywhere between mid May and mid June. The exact timing varies by year.
Altitude
4,551 metres (14,931 ft).
Is early May practical?
Usually not for crossing. The pass is typically still snow-covered or under active clearance in the first two weeks of May.
Is late May likely to work?
Possible in some years. Check the latest BRO updates and local reports before locking plans.
Is Chandratal accessible through Kunzum in May?
Unlikely for most of May. Chandratal road access usually lags behind Kunzum opening.
Who should consider postponing to June
Families, first-time Spiti travellers, anyone with non-refundable fixed dates, and those uncomfortable with plan changes.
Who may still enjoy May
Flexible travellers, snow lovers, photographers, bikers with mountain experience, 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 normal. The opening depends on BRO (Border Roads Organisation) snow clearance work, which typically starts in spring and progresses based on snowfall levels and weather conditions.
In past years, Kunzum has opened as early as mid May and as late as the second week of June. There is no pattern reliable enough to bet on. The only way to know for certain is to check the latest road status reports closer to your travel dates.
May is a transition month at Kunzum. The pass is caught between winter closure and summer access. If your entire trip hinges on crossing Kunzum, May carries real risk. If you have flexibility to adjust dates or routes, May can work, but only with proper backup planning.

Why May is tricky at Kunzum Pass
Understanding why May is uncertain helps you plan smarter instead of hoping for the best.
Winter snowpack
Kunzum sits at over 4,500 metres. Months of accumulated snow does not melt overnight. Even when the sun is strong in May, snow walls of 10 to 20 feet along the road are common. Clearance is a physical, machine-driven process, not something the weather does on its own.
Snow clearance timing
BRO begins clearing the route from both sides. 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 the snow melts, it often reveals broken road edges, washed-out patches, and loose gravel. The 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 open stretches near the top.
Kaza side vs Manali side
The road from the Kaza side to the top of Kunzum is shorter and often clears faster than the full Manali to Kaza route, which depends on the Gramphu to Batal section also being passable.
Early May vs late May at Kunzum Pass
Early May (1st to 10th)
In most years, early May is too soon for Kunzum. The pass is typically still under snow, and clearance work is ongoing. Some years the Kaza side approach becomes possible by the end of this window, but a full crossing from Manali to Kaza 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 you have a very flexible schedule.
Mid May (11th to 20th)
This is the hopeful window. In years with lighter snowfall, the pass starts becoming accessible by mid May. But this is not guaranteed. Road quality is poor even when open. Slushy patches, narrow clearance between snow walls, and unstable edges are common. If you are travelling mid May, keep your itinerary loose enough to accommodate a day or two of waiting.
Late May (21st to 31st)
Late May has the best odds in the month. In several recent years, the pass has been open by the last week of May. But there are also years where it stayed closed until the first week of June. If you can plan your trip 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.
Which side is more realistic in May?
From the Kaza side
The road from Kaza to Kunzum Pass is about 80 km via Losar. This side tends to become approachable a little earlier than the full Manali route because it is a shorter climb and does not depend on the 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 declared open. You drive up, experience the snow and the view at the top, and return to Kaza 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 side (entering through Kinnaur), the Kaza approach to Kunzum may be feasible even when the Manali route is not.
From the Manali side
The full 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 and broken road patches.
A full Manali to Kaza crossing via Kunzum in May is less likely than a Kaza-side visit. If this crossing is central to your plan, be prepared for the possibility that it will not work in May, and have the Shimla side as your backup entry into Spiti.
Can you cross Manali to Kaza via Kunzum in May 2026?
Maybe. But it depends 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 may open 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 more reliable in May than the Manali to Kaza crossing via Kunzum. This route stays at lower altitudes for longer and does not depend on Kunzum Pass being open. Many Spiti travellers use the Shimla side in May and do Kunzum as a day trip from Kaza if conditions allow.
Can you visit Chandratal through Kunzum in May 2026?
Unlikely for most of May, and possibly not even by the end of the month.
Kunzum Pass opening and Chandratal access are related but not the same thing. Even when Kunzum becomes crossable, the side road that branches off toward Chandratal Lake may still be blocked, uncleared, or too rough for vehicles. Camp operators near Chandratal typically do not set up until the road to the lake is properly passable, which often means mid June or later.
If you are planning a May trip specifically to see Chandratal, set expectations carefully. In most years, Chandratal access does not begin reliably until June. A late May visit to Kunzum top is realistic in a good year. A Chandratal visit through Kunzum in May is much less likely.
If Chandratal is your main goal, June is the safer month to plan around.
Weather and snow conditions at Kunzum Pass in May
Even on days when the road is technically open, conditions at 4,551 metres in May are serious.
Mornings are cold
Expect temperatures around minus 5 to plus 5 degrees Celsius at the pass itself, sometimes colder with wind chill. By afternoon, the sun can make it feel relatively warmer, but temperatures drop again fast after sunset.
Snow is the defining feature of Kunzum in May
Snow walls line the road where BRO has cut through. The ground near the pass can be a mix of compacted snow, slush, mud, and loose gravel. Walking at the top is doable but slippery in places.
Wind at the pass can be strong and biting
It adds to the cold and makes standing at the top uncomfortable after a few minutes. Clear-sky days are rewarding visually, but the wind does not stop just because the sun is out.
Visibility can drop suddenly if clouds roll in
Driving in low visibility at this altitude on a rough road is genuinely dangerous. If weather turns bad while you are near the pass, it is safer to wait or turn back than to push through.
What Kunzum Pass looks like in May
If you do reach Kunzum in May, the landscape is unlike the summer version. The whole area is white. Towering snow walls run along the road, sometimes higher than your vehicle. The barren brown mountains of summer are buried under snow, and the scale of it is striking.
The Kunzum temple at the top is likely still surrounded by snow. It is a tradition to stop here, and even in May, travellers who make it up leave prayer flags and circle the temple.
The broader valley views are spectacular, especially on clear days. You can see the Spiti Valley dropping away on one side and the Chandra range on the other. The snow softens all the sharp edges of the terrain.
It is photogenic in a raw, serious way. Not the green-meadow beauty of July, but something more dramatic and quiet.
Practically, the road surface at the top is rough. Patches of ice, slush, and mud are common. Walking around takes effort because of altitude and terrain. Go slow, take it in, and get back in the vehicle before the cold gets to you.
Local route tips most blogs miss
These are the things that actually matter when planning Kunzum Pass in May.
Losar matters as a staging point
Losar is a small village between Kaza and Kunzum. If you are approaching from the Kaza side, Losar is the last significant settlement before the climb to the pass. Road conditions between Losar and Kunzum can change from morning to afternoon. Local people in Losar usually have the best real-time sense of what is going on ahead.
Kaza is the safest planning hub
If you are in Spiti in May, Kaza should be your base. It has decent stays, food, fuel, and connectivity. From Kaza, you can do a day trip to Kunzum if conditions allow, and return to comfort and safety the same day.
Batal matters once the Manali side opens
Batal is the transit point on the Manali side, just below Kunzum. Once the full route becomes functional, Batal serves as a rest stop with basic dhabas. But in May, it may still be unreachable or barely operational.
Atal Tunnel open does not mean Kunzum is open
The Atal Tunnel is operational year-round. It takes you from Manali to the Lahaul side. But from the tunnel exit to Kunzum, you still need to cross Gramphu, the Gramphu to Batal road, and then the climb to Kunzum. The tunnel is just the first step. It does not guarantee the full route.
Flexible weather decisions matter in May
A clear morning might invite you to start the drive, but clouds building up by noon could mean you should turn back. In May, the weather changes fast at altitude. Make decisions based on real-time conditions, not a fixed itinerary.
May is for snow lovers, not certainty seekers
If you are excited by the idea of snow-covered passes, empty roads, and a landscape that feels like it is just waking up from winter, May has something special. If you need guaranteed access, smooth roads, and predictable weather, June is your month.
Is Kunzum Pass in May worth it?
Photographers
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 still thick, and you will have the pass to yourself on most days. But getting there is not guaranteed, so treat it as a bonus, not the purpose of the trip.
Bikers
Riding to Kunzum in May is for experienced riders only. The road conditions are rough, slippery, and cold. If you have ridden in challenging mountain terrain before and you know how to handle ice patches and gravel, it can be an incredible ride. If you are new to mountain biking, wait for June or July.
Self-drive groups
SUVs with high ground clearance and experienced drivers can make it in late May in a good year. Sedans and low cars should not attempt it. The reward is an uncrowded, snow-draped pass that most summer travellers never see. But the risk is real.
Families
May is not recommended for families, especially those with young children or elderly members. The altitude, cold, uncertain road conditions, and basic facilities along the route make it a stressful choice. June or later is a better fit.
First-time Spiti travellers
If this is your first Spiti trip, May adds too much uncertainty to what should be a memorable experience. You may spend days waiting for a road to open instead of actually exploring the valley. Plan for June or later, when the route is more reliable and the experience is more enjoyable.
What to carry for Kunzum Pass in May
The conditions at 4,551 metres in May are cold, windy, and unpredictable. Pack accordingly.
Thermals for top and bottom
A proper insulated jacket, down or puffer. A windproof outer shell. Warm socks and gloves. A woollen cap or beanie. Sunglasses with UV protection. Sunscreen with high SPF, because the UV at altitude is intense even when it feels cold.
Sturdy footwear with good grip
The ground near the pass is often a mix of ice, slush, and loose stone. Regular sneakers are not enough.
A water bottle and light snacks
Dry fruits, biscuits, or energy bars. There are no shops at the pass and very limited options along the approach.
Cash. INR 2,000 to 4,000 in small denominations
No ATMs between Kaza and the pass, and no digital payment without network.
Offline maps downloaded before you leave
Network coverage drops well before you reach the pass.
Basic medicines
including paracetamol, ORS, and Diamox (consult your doctor before carrying).A small first aid kit.
A fully charged power bank.
Safety and acclimatization
Kunzum Pass at 4,551 metres is a serious altitude. Add cold, wind, and potentially rough roads, and the physical demands go up significantly.
Acute Mountain Sickness (AMS) is a real concern, especially if you have driven up from Manali in a single day without acclimatizing. Symptoms include headache, nausea, dizziness, and unusual fatigue. The risk increases when you gain altitude quickly without giving your body time to adjust.
If you are approaching from the Kaza side, you are already at around 3,600 metres, which gives your body a better starting point. A day or two in Kaza before driving up to the pass makes a big difference.
If you are approaching from the Manali side and attempting a full crossing, the altitude gain is faster and more taxing. A halt at Chhatru or Batal (once functional) helps ease the transition.
Kids and elderly travellers need extra care. The combination of altitude, cold, and rough road is harder on them. If anyone in your group feels persistent headache, nausea, or confusion, descend immediately. Do not wait at altitude hoping it will pass.
Road open does not mean the trip is easy. Even when you can technically drive to Kunzum in May, the conditions test both the vehicle and the people inside it. Go prepared, go slow, and respect the mountain.
How to check real status before you go
This is the single most important step in planning Kunzum Pass in May.
Do not rely on a blog, a social media post from last year, or someone’s guess about when the road will open. The only reliable information is recent, local, and confirmed close to your travel date.
BRO updates
Border Roads Organisation occasionally shares road clearance updates on social media. These are the most official source, though they are not always timely.
Local operators and drivers
Travel operators based in Kaza or Manali who run regular Spiti trips have the most current ground-level information. They know which sections are clear, which are under work, and what vehicles are getting through.
Social media travel groups
Facebook and WhatsApp groups focused on Spiti travel often share real-time road reports from travellers who are already on the route. Cross-check multiple sources.
Spiti Valley Packages
If you are booking through an operator like Spiti Valley Packages, the team tracks road conditions daily during the opening season and adjusts trip plans accordingly. This is one of the practical benefits of having local support.
Check status in the last 48 hours before departure
A road that was open three days ago can close overnight after fresh snow. Confirm, then confirm again.
Common mistakes people 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 full Manali crossing
Reaching the top of Kunzum from Kaza for a day visit is very different from completing a full Manali to Kaza crossing through the pass. One can be possible while the other is not.
Assuming Chandratal will be open
Kunzum opening does not automatically mean Chandratal is accessible. The side road to Chandratal, camp availability, and lake-area conditions are separate factors.
Carrying light clothing because it is technically summer
May on the calendar does not translate to May conditions at 4,500 metres. Sub-zero temperatures, wind chill, and snow are normal.
Locking non-refundable plans
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 and fatigue
Driving to 4,551 metres on a rough road in cold conditions takes more out of you than you expect. Plan generous rest stops and keep your schedule light.
Not having a weather buffer
A single day of snowfall can close the pass for 2 to 3 days. If your trip has zero buffer days, one weather event ruins the entire plan.
Final verdict
Kunzum Pass in May 2026 is not a sure thing. It is a possibility that depends on snowfall, clearance, 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 willing to be flexible, May can be deeply rewarding. If you need certainty, smooth roads, and a reliable itinerary, June is the smarter choice.
The best approach for May is to enter Spiti from the Shimla side, base yourself in Kaza, and treat Kunzum as a day trip opportunity if conditions allow. That way, your trip does not depend on a single pass being open.

Frequently asked questions
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. Late May has better odds than early May, but nothing is certain until BRO completes the work. Always verify the latest status before travelling.
When is Kunzum Pass expected to open in 2026?
Based on historical patterns, Kunzum Pass may open between the third week of May and the first or second week of June. The exact date depends on snowfall levels and clearance progress.
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 tough Gramphu to Batal section.
Is late May a good time to visit Kunzum Pass?
Late May offers the best chance within the month. In years with lighter snowfall, the pass becomes accessible by the last week. But even then, road conditions are rough, cold, and require high-clearance vehicles.
Can I visit Chandratal through Kunzum in May 2026?
Unlikely. Even when Kunzum opens, the side road to Chandratal, camp setup, and lake-area access usually lag behind. Chandratal typically becomes reliably accessible from mid June onward.
Which side is easier in May, Kaza side or Manali side?
The Kaza side. The road from Kaza to Kunzum top is shorter 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 the road where BRO has cleared. The ground near the top is often a mix of compacted snow, slush, and gravel. The pass looks and feels like deep winter.
Is Kunzum Pass safe for self-drive cars in May?
Only for SUVs or vehicles with high ground clearance, driven by someone experienced with mountain roads. Sedans and low cars should not attempt it. Road conditions include ice, slush, narrow clearance, and unstable edges.
Is Kunzum Pass worth visiting in May for snow?
If you love dramatic, snow-heavy mountain landscapes and are comfortable with uncertainty, yes. Kunzum in May offers something most summer visitors never see. But the access is unpredictable and the conditions are challenging.
What should I carry for Kunzum Pass in May?
Heavy warm layers including thermals and a down jacket, windproof shell, gloves, warm cap, sunglasses, sunscreen, sturdy footwear, cash, offline maps, a power bank, basic medicines, and snacks.
Is there mobile network near Kunzum Pass?
No. Mobile network drops out well before you reach the pass from either side. BSNL postpaid may work intermittently near Losar, but do not count on it at or near the pass.
Where should I halt if weather changes near the pass?
From the Kaza side, Losar is the nearest settlement to fall back to. From the Manali side, Batal (if operational) or Chhatru are the realistic halt points. In bad weather, do not push forward. Wait or turn back.
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 a stressful experience for families. June or later is a much better choice.
What is the safest backup plan if Kunzum is still closed?
Enter Spiti from the Shimla side via Kinnaur. This route does not depend on Kunzum being open and is typically more reliable in May. You can explore the entire Spiti Valley from Kaza and treat Kunzum as an optional day trip if conditions improve.
