I just (17-July-2011) came back from Banjusa/Toli Peer, the road conditions over all not good, specually from Azad pattan to rawla kot the road is bad , and one patch of about 12-14 km is though somewhat leveled but not carpeted, where the rest is affected by bad patches in between.
Also it is rainy season now and there would chances of sliding and stone falling also
Hence go with all these conditions in your mind. The car will be thoroughly tested and travel would be tiring. As going on mountainous roads in bad conditions and not that SAFE turns is probably not a good idea currently
