Driving the unpaved National Highway 39 to Kotal-e Tamazan
Kotal-e Tamazan is a high mountain pass reaching an elevation of 2,413m (7,916ft) above sea level, situated on the provincial border of Urozgan and Daykundi in central Afghanistan. The pass is a critical logistical point on the National Highway 39 (NH39), a 56 km unpaved corridor connecting Gizab and Nili.

How challenging is the National Highway 39 to Kotal-e Tamazan?
The 56 km (34.8 miles) drive through Kotal-e Tamazan is a high-risk transit due to the primitive state of the National Highway 39. Technically, the road is a narrow dirt track with sustained steep gradients that test the cooling systems of heavy-duty vehicles. Logistically, the surface lacks any form of drainage or stabilization, making it prone to severe washouts. A high-clearance 4x4 vehicle is mandatory to navigate the deep ruts and the loose scree that characterizes the climb between Gizab and Nili. The lack of safety barriers on the most exposed mountain sectors leaves zero margin for steering errors.
What are the driving conditions on the NH39 between Gizab and Nili?
The National Highway 39 is subject to extreme seasonal variations. Technically, the 56 km route becomes a high-risk mud zone after localized rain, compromising tire traction and braking distance on the steep descents. Logistically, the 2,413m elevation and the rugged topography of the Urozgan/Daykundi border mean that rockfalls and debris accumulation are constant hazards. Drivers must account for the total absence of mechanical services or fuel points along the entire 56 km transit. Total self-sufficiency, including recovery gear and extra fuel, is the only logistical strategy for managing this isolated mountain corridor.
Is the road to Kotal-e Tamazan open in winter?
Due to its altitude and the lack of maintenance infrastructure, the NH39 through Kotal-e Tamazan is frequently impassable during the winter months. Logistically, heavy snowfalls and ice formation on the unpaved surface can block the pass for weeks, as snow-clearing operations are non-existent in this remote sector. Technically, the route is also subject to unstable geological conditions that increase the risk of road collapse during the spring thaw. Beyond the mechanical and environmental challenges, the security situation in the region is highly volatile, requiring an exhaustive pre-trip risk assessment before attempting any transit between Gizab and Nili.
