When the roads open
The road from Shimla through Kinnaur is open for most of the year, but snow and landslides can close it for days. The road from Manali, through the Atal Tunnel and over Kunzum pass at about 4,590 m, usually opens in late May or June once snow is cleared, and closes with the first heavy snow in mid or late October. Dates vary every year, so check before you plan a Manali–Spiti route.
