Two roads, two seasons

Spiti is a cold desert at 3,000–4,500 m on the Tibet border. Access, not weather, sets the season, because there are only two roads in.

Shimla–Kinnaur–Kaza: open most of the year. It is long (about 420 km from Shimla to Kaza) and slide-prone in the monsoon, but it climbs gradually, which helps your body adjust to altitude.
Manali–Atal Tunnel–Kunzum La (4,590 m)–Kaza: open roughly from mid-June to October, depending on snow. It is shorter, about 200 km, but the Batal–Losar stretch is rough, with stream crossings.

A full circuit, in via Kinnaur and out via Manali, is only possible while Kunzum is open.

Mid-June to September

The main season. Chandratal Lake (about 4,300 m) is reachable and its camps operate. July and August are the busiest, with bikers and SUV groups. Spiti itself gets little monsoon rain, but the Kinnaur stretch and the Manali side can be hit by slides and swollen streams, so carry a buffer day.

May and October

Quieter and colder. Kunzum and Chandratal are normally shut in May, and the camps start packing up in the first week of October. Expect nights below zero in Kaza.

November to April

Spiti under snow. The Kinnaur road usually stays open, with closures after storms. Homestays in Kaza and Kibber run winter trips, including snow leopard spotting from January to March. Expect –20°C nights, frozen pipes and power cuts.

Indian citizens do not need a permit for Kinnaur or Spiti. Foreign nationals need an inner line permit for the border stretch between Jangi and Sumdo, issued at Reckong Peo or Kaza.

Frequently asked questions

Which is the best month to visit Spiti Valley?

Late June to September suits most travellers, because both entry roads and Chandratal are open, allowing a full circuit from Shimla to Manali. September is the sweet spot, with dry roads after the monsoon, clear skies and thinner crowds. July and August are good but busier, with a higher chance of slides on the Kinnaur and Batal stretches.

Is Spiti Valley open in winter?

Yes, via Shimla and Kinnaur only. The Manali side and Kunzum Pass stay shut from about November to June. Winter trips need a 4x4 or an experienced local driver, heavy down clothing and flexible dates, because snow can close the road for days. Kaza's homestays stay open, but water and power are unreliable.

When does Kunzum Pass open?

Kunzum Pass usually opens to traffic between mid-June and the end of June, once the Border Roads Organisation and the state public works department clear the snow. It normally closes between late October and November. The exact dates shift every year, so check Lahaul-Spiti district updates before planning a Manali–Kaza crossing.

Do Indians need a permit for Spiti Valley?

No. Indian citizens can travel throughout Kinnaur and Spiti with a valid photo ID such as an Aadhaar card or passport, and should carry it at police checkposts. Foreign nationals need an inner line permit for the border stretch between Jangi and Sumdo, available at the SDM offices in Reckong Peo or Kaza.
