hi sarmad..
Road condition uptill sharda is good and you can easily drive upto there... but from sharda onwards (kel) you will be needing a high ground clearance vehicle preferably a 4x4,.. I hv returned from Neelam on 12th June 2015, and i went upto taobat driving my own pajero. awesome weather, raining mostly so you have to be careful in driving,, as there wud be mud patches along your way, drive slow and do not apply breaks while driving on mud.. try to control your car maximum by gear.. In sha Allah you will have a good time.. Good Luck and God Bless.
