Is Spiti accessible by road during heavy snowfall in winter?

During heavy snowfall in winter, accessing Spiti by road can be challenging and is often restricted. The high mountain passes leading to Spiti, such as Kunzum Pass and Rohtang Pass, are prone to heavy snow accumulation, leading to road closures for safety reasons. Typically, the road to Spiti from Manali is closed from late October to early May. The road from Shimla via Kinnaur Valley remains open for a longer duration. Travelers planning a winter visit should check road conditions, weather forecasts, and travel advisories, and it’s advisable to undertake the journey when the roads are officially open and safe.
