Approx 12.5 k for entire trip including everything (fuel, khapa, stay, entry tickets to different places). U get respect if u give repect to others. Some people in Naran and Babusar area not to eat meat in Hunza due to difference of Sect (Hunza people are mostly Ismaili, The most educated and peaceful sect of muslims in my view. Some may differ). The place where I camped in Hunza only charged me Rs.300 for camping and he provided me with free meal and tea. I love people of Hunza and regions beyond due to their simple loving nature. There is commercialization in few areas but overall they are 1000 times better than people of Murree and Naran. Baqi story aagay a rahi hai InshALLAH
