Winter Spiti vs Summer Spiti Tour - What's Open After October and Which Route Still Works

Every year around October, the same question reaches travel desks: is Spiti still open? The honest answer is that part of it is, and part of it isn't. Spiti doesn't shut completely in winter, but one of its two roads does, and that changes what a trip looks like. Here's what is open after October, which route still works, and how winter Spiti compares with summer.

The Two Routes Into Spiti

●        Manali route (summer only): Manali, the Atal Tunnel, Gramphu, Batal, Kunzum Pass, Losar and Kaza. It is the shorter way in, but it depends on Kunzum Pass at about 4,590 m, which usually closes between mid-October and early November. Snow can also arrive suddenly. The Tribune reported seven tourists stuck near Kunzum after unexpected mid-October snowfall, with traffic blocked on the Gramphu-Kaza road.

●        Shimla-Kinnaur route (year-round): Shimla, Narkanda, Sangla or Kalpa, Nako, Tabo and Kaza, along the Hindustan-Tibet road (NH-5). It has no high pass, so it generally stays open through winter, apart from temporary closures after heavy snow or landslides.

Once Kunzum closes, the Shimla side is the only way in. Outlook Traveller's 2026 season guide notes that the Manali road usually closes by late October and that even the Shimla highway can see temporary closures, so a winter trip needs slack in the schedule.

What's Open and What's Closed After October

●        Open: Kinnaur (Sangla, Kalpa, Nako), Tabo, Dhankar, Kaza, and the main sights near Kaza such as Key Monastery, Kibber, Langza and Hikkim, usually reachable but subject to snow clearing.

●        Closed: Kunzum Pass, the Kaza-Losar stretch beyond it, and Chandratal Lake. The Manali-Kaza circuit and the loop exit via Manali are not possible until late May or June.

Closure isn't a short blip. In one year the pass stayed shut for around nine months, 

Summer Spiti vs Winter Spiti

●        Summer (June to mid-October): Both routes open, the full circuit is possible, and Chandratal and Kunzum are on the itinerary. Days are mild, though nights are cold. September is the sweet spot, with clear skies and stable roads.

●        Late October to November: A risky in-between. Kaza is reachable via Shimla, but early snow can shut Kunzum at short notice, so don't plan a Manali exit.

●        Winter (December to March): A very different Spiti. Villages are under snow, rivers freeze, and temperatures can fall to around minus 30 degrees Celsius in the coldest weeks. It's also the season for snow leopard spotting trips, which run with local guides around Kibber and nearby villages.

Who Should Consider Winter Spiti

Winter Spiti is stunning but demanding. It suits experienced, fit travelers who value solitude and photography over comfort. It's not a good first Spiti trip, and it's not suitable for small children, older travelers, or anyone with heart or breathing problems, since altitude and extreme cold make medical help hard to reach.

Practical Tips for a Winter Trip

●        Go in from Shimla and add at least two buffer days for snow or landslide delays.

●        Use a high-clearance vehicle with an experienced local driver who knows winter conditions.

●        Confirm that your homestay is open and heated. Many close in deep winter, and frozen water pipes are common.

●        Fill your tank early and carry cash. Fuel and ATM options are very limited beyond the main towns.

●        Plan gradual acclimatization. The Kinnaur-to-Kaza climb helps, but don't rush the first day at Kaza.

●        Check road status the same week you travel, using the Lahaul-Spiti district administration's updates and local news, not last month's information.

The Bottom Line

Spiti is open all year, but the Spiti you can reach changes with the season. Summer gives you the full circuit with Chandratal and Kunzum; winter gives you a quieter, harsher valley reachable only from the Shimla side. If you want the classic loop, wait for the June to September window. If you want snow and silence, go in winter, but plan it carefully.

At Royal Rover Holiday, we plan Spiti Valley tours around the season, not around a fixed template: Shimla-side entry in winter, the full circuit in summer, and honest advice if your dates fall in the risky shoulder weeks. Share your dates and group, and we'll tell you what's realistic.
