Hunza is the valley that made Pakistan famous to international travellers. Karimabad, the main town, sits at 2,438m with Rakaposhi (7,788m) and Ultar Sar (7,388m) forming its backdrop: one of the most dramatic mountain-town juxtapositions on earth.
The valley was an independent kingdom for centuries: the Hunza Mirs ruled here until 1974. The legacy of that long, separate history is visible in the ancient forts, the distinct Burushaski language, and the valley's famously warm hospitality.
Hunza is usually visited as part of a combined Skardu-Hunza itinerary with Raahi, though it absolutely merits a standalone trip for those with less time. The drive from Gilgit to Karimabad along the Karakoram Highway is itself a destination.
