Bolan Pass cuts through the mountains of Balochistan as a long, winding gorge, linking the high valley of Quetta with the plains of Kachhi and Sindh. Cliffs rise on either side of the Bolan River, and the road and railway follow the narrow valley through tunnels, bridges and dry riverbeds.
For centuries the pass was a major route for traders, travelers and armies moving between the Indus plains and the Iranian and Afghan highlands. In the 19th century the British built a railway through it, which is still one of the most scenic and dramatic railway routes in the country. Near the lower end lies Mehrgarh, an archaeological site where farming settlements date back thousands of years, among the oldest known in South Asia.

Stretching as a long mountain corridor, the pass follows the steep rock walls of the gorge and the seasonal Bolan River alongside the historic Bolan railway line with its remarkable tunnels, bridges and steep gradients. Key highlights along the route include the settlements of Kolpur and Mach, known for coal mining and railway history, the gateway town of Dhadar, and the nearby Neolithic archaeological site of Mehrgarh. Visitors can also explore the picturesque springs and waterfalls of Pir Ghaib, making it a scenic journey through both rugged landscapes and ancient history. Morning and late afternoon bring softer light on the cliffs and cooler air in the gorge.
