How do I reach Naltar from Islamabad?

Reach Gilgit first (flight or KKH), then jeep to Naltar. Many packages sell Naltar as a day trip from Gilgit or a short overnight. Group tours often include transport and hotels. See /destinations/naltar and /blog/naltar-tour-packages-from-islamabad, then book a listing on /adventures?query=Naltar.
