well, this is one of the most beautiful route.. i myself have not fully attempted it fully (trekked only up to kamri top) but according to one of my friends who did it in recent years has a bad experience due to army restrictions..
please seek permission from ARMY officials before attempting this one. else u can be in trouble.
besides, if u have permission than there is no problem at all, army is there to help you in every aspect. just go and enjoy
