Best Time to Visit Spiti Valley: A Month-by-Month Guide
Spiti is two completely different valleys depending on when you arrive. Here is what each month actually looks like from behind the wheel — road status, temperatures and what you can realistically reach.
Spiti has two personalities. From roughly June to early October it is a full circuit valley — you can enter from Shimla and exit over Kunzum La to Manali. For the rest of the year Kunzum La is shut and Spiti becomes a dead-end corridor reached only through Kinnaur, which is exactly what makes the winter run so compelling.
The short answer
For a first visit, mid-June to mid-September is the easy window: both entry roads open, Chandratal accessible, and night temperatures manageable. For the frozen version of the valley — snow-locked villages, empty roads and −25°C nights — January and February are the months, and only with a properly prepared 4×4.
| Season | Months | Roads | What you get |
|---|---|---|---|
| Late spring | May – early June | Kinnaur open, Kunzum La usually shut | Quiet valley, cold nights, no Chandratal |
| Summer | Mid-June – Aug | Full circuit open | Chandratal, Komic, Hikkim, green Kinnaur |
| Autumn | Sep – early Oct | Full circuit, closing late Oct | Best light and clearest skies of the year |
| Winter | Nov – Apr | Kinnaur route only | Frozen waterfalls, snow villages, near-zero traffic |
Month by month
April and May
The Kinnaur side thaws first. Roads to Kaza are usually passable by late April, but Kunzum La stays under snow, so the Manali exit is off the table. Expect daytime highs around 10–15°C and nights near freezing. Good for photographers who want the valley to themselves without full winter commitment.
June to August
The circuit season. Kunzum La typically opens in June, which unlocks Chandratal and the loop back to Manali. This is also the monsoon window for the lower Kinnaur stretch — Spiti itself is a rain shadow desert and stays largely dry, but landslides between Rampur and Pooh are the real risk. Build one buffer day into any June–August plan.
September and early October
Our favourite driving window. The monsoon has cleared out of Kinnaur, dust is settled, the light is hard and clean, and the crowd has thinned. Nights drop fast — expect −5°C at Kaza by late September. Kunzum La normally closes with the first serious snowfall in mid to late October.
November to March
Winter Spiti. Only the Kinnaur road stays open and even that is a daily judgement call. Villages like Langza and Komic sit under a metre of snow, the Spiti river freezes in stretches, and homestays run on bukharis and heavy quilts. Nights hit −20°C to −25°C. This is a convoy-and-recovery-gear trip, not a solo hatchback trip.
The valley does not get harder in winter. It gets slower — and slow is where Spiti actually opens up.
Choosing between summer and winter
- First time at altitude, travelling with family, want Chandratal — go summer.
- Comfortable with cold, want photography and silence over sightseeing — go winter.
- Limited to 6–7 days from Shimla — summer circuit is the safer fit.
- Want the fewest people on the road at any cost — February.
Acclimatisation matters more than the month
Kaza sits at 3,800m and the day hikes above it push past 4,500m. Whichever month you pick, structure the drive so you gain altitude over two to three days rather than one. We cover the practical side of that in our guide to preventing altitude sickness in the high Himalayas.
Frequently asked
- When does Kunzum La open for Spiti Valley?
- Kunzum La usually opens between late May and late June depending on snowfall, and closes again with the first heavy snow in mid to late October. Until it opens, Spiti can only be reached via Shimla and Kinnaur.
- Is Spiti Valley open in winter?
- Yes. The Kinnaur route to Kaza stays open through winter and is cleared regularly, though it can close for a day or two after heavy snowfall. The Manali route over Kunzum La is shut from roughly November to May.
- How cold does Spiti get in January?
- Daytime temperatures in Kaza hover between −5°C and 0°C in January, with nights falling to −20°C and occasionally −25°C in villages like Langza and Komic.
- How many days do you need for Spiti Valley?
- Eight days is a comfortable summer circuit from Shimla with time to acclimatise. Winter itineraries run around nine days because daily distances are shorter and weather buffer days are essential.
