A small valley on the slope of Mount Sikaram encompasses a number of villages, districts, and tribal regions—many historically significant—including Peiwar, Alizai, Tari Mangal, Narai, Speena Shaga, and Khewas. The Gawi Pass, also known as the Peiwar Kotal Pass, runs between the Kurram Valley and Afghanistan's Aryub Valley; it connects the Paktia Province of Afghanistan with the Kurram District of Khyber Pakhtunkhwa province in the Ex Federally Administered Tribal Areas of Pakistan.
