The short answer. For the classic Spiti trip — green valleys, every road open, Chandratal reachable — go between mid-June and late September. For snow, empty villages and the trip most people remember longest, go in January or February. March to May and October to November are the in-between months: quieter and cheaper, but with a shorter list of places you can actually reach.
Two seasons, two different valleys
Spiti sits in the rain shadow behind the main Himalayan range, at between 3,000 and 4,600 metres. That one fact decides everything about when to come. It barely rains here even in the monsoon, the air is thin all year, and the difference between June and January is not a few degrees — it is a different landscape with different roads.
In summer the valley is brown and gold with green strips of barley and pea fields along the river, every village is reachable, and both roads in are open. In winter the same villages sit under snow, half the side roads are shut, the population of Kaza thins out, and you have the valley very nearly to yourself. We run both, and they are different trips on different roads: seven days out and back from Shimla in winter, eight days as a loop from Manali in summer.
Month by month
January and February — deep winter
The coldest and the clearest. Days in Kaza stay below freezing and nights reach around −20 °C. The Shimla road stays open most of the winter, so the valley is reachable; the Manali road is shut. Snow lies over Kaza, Komic, Hikkim and Langza, the light is extraordinary, and there is no one else on the road. This is our winter season, and it is the trip people talk about afterwards. It asks more of you: proper clothing, patience when weather moves a day, and a willingness to sleep in a room heated by one iron stove. If that sounds good rather than grim, this is your month. We cover it in full in is Spiti safe in January?
March and April — the thaw
Still cold, still snowy in the high villages, and the days are getting longer. The Shimla road is open, the Manali road is not. Fewer departures run in these months because the weather is less predictable than midwinter — the freeze-thaw cycle brings more stones down onto the Kinnaur road than either the settled cold of January or the dry heat of summer.
May — the shoulder
Kinnaur is in blossom and the lower valley is beautiful. Spiti itself is still cold and only partly open, and Kunzum La — the pass on the Manali side — is usually still under snow. A good month if you want the Kinnaur half of the route without crowds and do not mind that Chandratal is out of reach.
June to early July — the best of summer
For most people this is the answer. The Manali road usually opens in June once Kunzum La is cleared, every village is reachable, Chandratal opens for the season, the barley is green and the nights in Kaza only just touch freezing. It is also the busiest stretch of the year on the Manali side, so book ahead.
Mid-July and August — the monsoon
Spiti itself stays dry — it is a high desert, and the monsoon mostly does not get over the range. The problem is the approach. The Kinnaur road follows the Sutlej through steep, loose country, and heavy rain in the lower valleys brings down landslides and shuts the road for hours or, occasionally, days. The valley is lovely; getting to it is the gamble. If your dates are fixed and you cannot lose a day, pick another month.
September — the quiet favourite
Our own pick for a first summer trip. The monsoon has pulled back, the air is washed clean, the light is long and low, and the harvest is on in the villages. Everything is still open, and there are far fewer vehicles than in June. This is the last month of our summer season.
October — the closing door
Clear, cold and emptying out. Kunzum La and the Manali road usually close with the first heavy snow, most years somewhere between late October and the middle of November, and the date is never announced in advance. The Shimla road stays open. Beautiful, but plan it as a one-way trip in from Shimla rather than a loop.
November and December — into winter
The in-between weeks. Cold is settling in, the valley is mostly empty, and the winter stays are not all open yet. December gets close to the January trip without quite the depth of snow. Our winter departures start in January for exactly this reason.
Which road is open when
This is the part that catches people out, so it is worth stating plainly. There are two roads into Spiti and they do not have the same season.
- Shimla, up the Sutlej through Kinnaur. Open all year in most winters. Longer and lower, which is exactly why we use it: you gain height over three days instead of one. Closures happen and are usually a matter of hours.
- Manali, over the Atal Tunnel and Kunzum La. Shorter and far more dramatic, and open only for the summer months — roughly June to October, depending on the snow. It is shut for the rest of the year.
Our winter circuit has to use the Shimla road; our summer one goes in that way and comes back over Kunzum La, which is the whole argument for a summer loop. Both are set out in Manali to Spiti by road. Zanskar and Ladakh are summer-only and start in Manali, because their passes are shut the rest of the year.
Best month for what you want
- Your first time in Spiti: September, then June.
- Snow and empty villages: January or February.
- Chandratal and the Manali side: mid-June to early October, and no other time.
- Zanskar or Ladakh: July and August. Pensi La, Singe La and the Manali–Leh passes are only open then.
- Photography: late September for colour and long light; January for snow and clean air.
- Avoiding other vehicles: September, or any winter month.
- Travelling with older parents or children: September — warm enough, everything open, and the gentlest version of the altitude.
Whichever month you pick, climb slowly
Kaza is at about 3,800 metres and Komic, the highest village on our route, at 4,587. Altitude does not care which month it is. The Shimla approach climbs gradually — Sangla at 2,680 metres, then Nako and Tabo, then Kaza — so your body has three days to catch up, and the highest point of the trip is a day visit rather than a night. An expedition medic travels with every convoy and checks oxygen and pulse morning and evening.
When to book
Each departure is capped at twelve guests, and the popular dates fill months ahead. Three to six months out gives you the real choice of season and dates. Overseas guests also need an Inner Line Permit, and we need scanned documents about six weeks before departure — see Inner Line Permits for Spiti.
Questions we are asked
What is the best month to visit Spiti Valley?
For a first trip with every road open, September and then mid-June are the best months. For snow and empty villages, January and February. There is no single best month: summer and winter are two different trips on the same circuit.
Is Spiti Valley open in winter?
Yes. The road from Shimla up through Kinnaur stays open through most of the winter, which is why our winter departures run from Shimla. The Manali road over Kunzum La is closed by snow from about November to June.
Can you visit Spiti in the monsoon?
Spiti itself stays dry in the monsoon because it lies in the rain shadow, but the approach road through Kinnaur can be blocked by landslides after heavy rain in July and August. If your dates cannot move, pick another month.
When does the Manali to Spiti road open?
Usually in June, once Kunzum La has been cleared of snow, and it closes again with the first heavy snow, most years between late October and mid-November. The exact dates change every year and are not announced in advance.
