JournalA Road Trip Through Spiti Valley: Mountain Roads and High-Altitude Landscapes
In short: Spiti is a high-altitude cold desert in Himachal Pradesh, with Kaza at about 3,650 m. The Shimla route (about 412 km) is open year-round but difficult and climbs gradually, which helps acclimatisation. The Manali route over Kunzum Pass (4,590 m) is summer-only and considered treacherous.

What Spiti is
Spiti lies in the rain shadow of the Himalayas, so it is barren, cold and dry, with little monsoon rain. Temperatures range from about -25 C in winter to about 15 C in summer. Heavy snow can cut the sub-division off from the district headquarters for five to six months.
Two ways in
Altitude sickness is a real risk. Travellers from low elevations are advised to take the Shimla route. Read driving in the Himalayas before you decide.
| Route | Season | Character |
|---|---|---|
| Shimla, along the Sutlej | Year-round, but difficult | Gradual climb, better for acclimatising |
| Manali, Atal Tunnel and Kunzum Pass | Summer | Shorter, higher, described as treacherous |
