Is Spiti open in December? Road by road

Yes, Spiti is open in December. Through Kinnaur. Only through Kinnaur.

The Manali side shuts every winter by government order, and the Atal Tunnel doesn’t get you around it. The Kinnaur side is officially “almost all-weather”, which is a careful phrase. It means open until the day it isn’t.

So the useful question isn’t whether Spiti is open. It’s which road, on which morning, and how many spare days you’ve got when the answer changes.

The roads, one at a time

Stretch	What December usually means	What the record says
Shimla – Rampur – Pooh – Sumdo (NH-5, Hindustan–Tibet road)	Open, with interruptions	An avalanche blocked it near Tinku nullah, Pooh, in Jan 2023. Snow shut Pooh to Samdu (Sumdo) in late Jan 2026
Sumdo – Tabo – Kaza (NH-505)	Open, with interruptions	The district calls Shimla to Kaza “almost all-weather”
Kaza – Losar (NH-505)	Don’t count on it	The state’s emergency centre listed “Kaza–Gramphu” as blocked in Jan 2026, without saying where
Losar – Kunzum – Batal – Gramphu (NH-505)	Closed by order	Shut on 23 Nov in 2024 and 25 Nov in 2025
Manali – Atal Tunnel – Gramphu	Gets you to Lahaul, not to Spiti	The tunnel gets you into Lahaul. The closed stretch starts beyond it, at Gramphu, and the tunnel route itself depends on the weather
Key, Kibber, Dhankar, Langza, Hikkim, Komic, Mud	Road by road, day by day	No official winter status exists for these. Ask in Kaza

The Manali side, and why nobody should try it

Kunzum La stands at 4,550 m. The district’s own page calls the road over it generally motorable from early August to late September. Recent years have run past that at both ends, which tells you how loose those dates are. Here’s how the last two years went:

When	What happened
23 Nov 2024	Gramphu to Losar closed “until the next summer”, on the advice of BRO and the district police
24 May 2025	BRO reported the stretch restored after about seven months, with only a few 4x4s through and general traffic not yet allowed
6 Oct 2025	Snow blocked Kunzum, seven weeks before the formal closure
14 Oct 2025	Reopened, for light 4x4s only
25 Nov 2025	Gramphu to Losar shut again until further orders, citing black ice and extreme cold. The order came out on 21 Nov

Two things follow from that.

First, this isn’t a warning you can weigh up. The 2024 order barred all movement on the road and made breaking it punishable under Section 51 of the Disaster Management Act, 2005, with up to a year in prison, a fine, or both. The reasons given included passengers trapped by sudden snowfall earlier, and how risky rescues are in those conditions.

Second, the last two orders landed within two days of each other, and snow doesn’t wait for paperwork. As of 14 Nov 2026, no order for this winter had turned up. Check for it, and plan as though it has already come.

Chandratal sits on the closed side too. In December, forget it. The passes guide has Kunzum in context with everything else up there.

The Kinnaur side, and what “almost all-weather” costs you

The district puts Shimla to Kaza at about 412 km and about 20 hours of driving, not counting an overnight halt. That’s the summary. The December version is slower, and it’s the one road in. If it shuts behind you, you wait. If it shuts ahead of you, you wait somewhere less comfortable.

In January 2026, when heavy snow hit, the state’s emergency centre counted 292 blocked roads in Lahaul and Spiti alone. That was one spell. December doesn’t always bring one, and nobody can tell you in November whether yours will.

The six-day winter plan on this site was driven in March 2025, in a Maruti Jimny, and it has a buffer day built in for exactly this reason. In December, one buffer day is the minimum. If your leave ends on a fixed date with no slack, this isn’t the month.

Should you ride it

This site’s winter Spiti trip was four wheels, not two, and it’s a March trip, so there’s no first-hand December motorcycle report from Spiti here to lean on.

What can be said plainly: black ice is the reason the district gave for shutting Gramphu to Losar in 2025. A motorcycle has two small patches of rubber on that surface, and the sections you can’t see from a distance are the ones that matter. Snow chains, traction boards and a shovel are car answers. Most of the kit that makes winter Spiti manageable doesn’t transfer to a bike.

How cold

Tabo is the Spiti station that keeps showing up in the reports: minus 10.6°C in mid-December 2024, and minus 10.2°C in early January 2026. Those were the lowest figures in the state-wide reports on those days, and Tabo sits lower than Kaza.

No dated official December minimum for Kaza turned up while checking this page, and the January 2026 report noted that official data isn’t available for remote, high-altitude areas. So treat any precise Kaza figure with suspicion, including the dramatic ones.

Altitude doesn’t take winter off either. The district lists Losar at 4,085 m, Key at about 4,115 m and Kibber at about 4,330 m. The US CDC says unacclimatised travellers sleeping at about 2,450 m or above are at risk of altitude illness, that two to three nights around 2,450 to 2,750 m before going higher is strongly protective, and that symptoms getting worse at rest mean going down. Talk to a doctor before you go, especially about medication.

Permits on this route

If you’re Indian: the official district pages for Kinnaur and Lahaul and Spiti only talk about foreigners. One detailed travel guide says Indians need no permit but must register at the Jangi and Sumdo checkposts with ID and the vehicle RC. A Business Today piece from October 2026 says areas beyond Sumdo need passes, without saying who or under what rule. Carry ID and your vehicle papers, and ask at the first checkpost.

If you’re not Indian: you need a protected area permit. The Lahaul and Spiti page lists Khab, Samdo, Dhankar, Tabo, Kaza and others as protected, and gives the group size as four or more. The Kinnaur page says two or more, through a recognised Indian travel agency, for 30 days, with a ₹200 fee per person. Those two official pages disagree, and you enter from Kinnaur, so sort this out with the Deputy Commissioner’s office in Reckong Peo before you get there. Don’t assume a permit can be collected at the far end, because the Kaza office is on the wrong side of the checkposts.

Where to actually check

The obvious place is the worst one. On 9 Nov 2026, the district’s road status page said “Keylong to Kaza: Closed” and was last updated on 14 May 2024. It’s a page, not a feed.

In order of usefulness:

1. Your stay in Kaza or Tabo. Call the evening before. They know whether the truck came through. Not every place stays open in winter, so this call also confirms you still have a bed.
2. The State Emergency Operation Centre’s evening public utility report. It’s the source behind the road-closure numbers in the wire stories, so search the news for the latest figures by district.
3. The first checkpost. Ask the people standing on the road that morning.
4. District helplines. The Lahaul and Spiti site lists 1077 for the Commissioner of Rescue and Relief and 155300 for the Citizen’s Call Center.

If you do go, pack for the cold you can’t predict. The packing list covers the basics and the winter plan covers the rest. If December starts to look thin on margin, the late May route through Kinnaur is the same road with a lot less to go wrong.

Open is a daily decision up there. Keep a day spare and let the road make it.
