Bro security is no concern. Its completely safe & secure area. Just go there, see the ground reality and then you will change ur views like I changed mine. The reason is that its whole area is under influence of Jamali tribe who are also MNA of this seat.. they have put up strict policy against crime.
Jeeps are required to climb uphill. The last point where u can take ur vehicle is Wahi Pandhi. But its advised to go till Juhi and hire jeep from there. Juhi to Wahi Pandhi is bad road.
Need anymore info, feel free to ping me or ahmed.
