Darra Adam Khel is one of the more unusual attractions in Pakistan — a small bazaar town whose entire economy revolves around a single trade: making guns. Located in the Tribal Areas, 40 kilometres south of Peshawar on the road to Kohat, it is a drive of about 40 minutes.
The town is lined with small workshops openly producing copies of almost every weapon imaginable — AK-47s, pistols, rocket launchers — alongside bullets sold by the cartridge. Shopkeepers invite visitors in to inspect (and buy) their wares. Visitors can pay to fire weapons at a range. It is noisy, chaotic, and extraordinary. See the gun bazaar page for more. The road in from Kohat now passes through the modern Kohat Tunnel under the Khigana ridge.
Note that the area carries genuine risk. The government's effective control is limited. Check current advisories carefully before visiting.
