Leh plans in july end... need help in planning...?

Happy journey. I will not suggest you to travel by bikes from Manali to Leh or Srinagar. It is very tough route. However, if you have decided to travel by this means only then it is better to contact the Tourism Department (Manali), they can help you. Please read maps also. In Leh and Srinagar also you can contact Tourism Department. Since all the three places have big tourist inflow therefore the Tourism Departments at these places are working efficiently, though Manali and Leh-Srinagar are from two different States.
