June to October is the best season to visit Ladakh... you should also check the route with the other travel agencies who organises road trips..
Deyor Camps I will suggest you.
June to October is best time to visit there Just take care of the papers of your respective bikes because I have heard from various travellers that the taxi drivers there are very strict due to rented bikes and cars from other states because their source of income is decreasing. They can check your bike papers to ensure that those are your own property or not. Otherwise it is a great tour. Happy journey.
Depends year to year. Generally it is open. if you are going through Manali you can go upto there and know about the road from there... you can try out a week or two later. it wud be safer
During this time, only the Srinagar-Leh highway opens up and thus, this is just not the right occasion to visit. But during early June, Manali road opens up along with Rohtang Pass. However, the initial 7-10 days are really not suitable for traveling. The reason for the same is that the area experiences recurring blockages.
