I will share the route to Spiti from Srinagar. If you take Pulwama route via Kishtwar Sissu kibber you reach Spiti valley by 17 hours drive. It’s better to take a break at Sissu and restart your journey next day. From Spiti Chitkul is 14 hours away. You could take a break at jibhi or at Kullu. Before November end if you could plan the trip you would not only enjoy riding but the weather is great. Snow starts by December.
It will take you approximately a little over 19 hours to reach Chitkul & the distance is around 749.9 km!! The best route would be via NH 44 & NH 5!! The best months to visit Chitkul Valley are March, April & May!! Happy journey 🙌
