Try to go skardu by passing deosai that is the shortest way
otherwise you have to come back at KKH (jaglot) and then go to skardu Distance is around 200km from jaglot to skardu . From skardu to deosai around 55-60km
2nd option is not good enough
Deosai camping is tottaly safe and plan some BBQ as there is no restaurant but a wide range of plateau
Astore to depsai most part of the road is muddy but you dont need to worry as you have Double Cabin
