Bolan Pass
The Bolan Pass, at an elevation of 1,793 m (5,884 ft) above the sea level is a high mountain pass through the Toba Kakar Range of Balochistan province in western Pakistan, 120 kilometres from the Afghanistan border.
It’s important to be prepared on this road. At a distance of 120 km from the border of Afghanistan, Bolan Pass is a mountain pass in Balochistan Province of Pakistan which connects the Jacobabad and Sibbi to the Quetta city. Check weather forecasts before leaving home, and remember that it becomes cooler and often more prone to storms at higher elevations.
The weather on this zone is harsh and highly unpredictable and it does not take much time for the bright sun shine to change over to moderate to heavy snow fall. The Bolan Pass is only open at this time for locals and aid workers and it’s an alternative to the Khyber Pass further north. This area is definitely not safe. You should get an armed guard with you. A sudden drop in the temperature, even in summer, can trigger winter-like conditions. It has a well-deserved reputation for being dangerous because of unpredictable snowstorms and blizzards, and driving under these conditions, can be extremely challenging.
Watch out for sudden loose-gravel breaks. This pass has a significant history background being a mountain pass, which connects the Central Asia and South Asia. Along Bolan Pass where the road winds through picturesque mountains one is reminded of the huge odds that the armies from Central Asia and the South must have faced in their raids on the plains of the present day Pakistan.
