For many centuries, the Bolan Pass has been the main entrance to Quetta District. It is historically significant, used as the gateway by most of the immigrants from Central Asia in their drive to discover new homelands in South Asia. The two other important passes are the Lak Pass between Kalat and Quetta and the Khojak Pass near the border with Afghanistan at Chaman.
Lak Pass is located between Kalat and Quetta at a point where the highway makes a turn for Koh-e-Taftan, Saindak copper mines and Zahidan in Iran and the other section links Karachi via Kalat, Khuzdar and Bela. PTDC Motel at Khuzdar and Taftan caters for motorists. The view from the top of the pass is interesting. Trucks, trailers and lorries laden to their brim with merchandise and passengers move along at great speeds. Down below these kiosks sell beverages. On the hill, unmindful of the presence of the motorized transport and the human beings, hundreds of sheep browse upon the scant herbage available there.
Along Bolan Pass where the road winds through picturesque mountains one is reminded of the hugs odds that the armies from Central Asia and the north must have faced in their raids on the plains of the present day Pakistan. In winters, trains of camels, as they slowly plod their way through to the top, look fascinating. The Bolan links Quetta with the plains of the Punjab and the upper Sindh through the town of Sibi by road and train. The train passes through 21 tunnels.
The Khojak Pass is 7575 ft. above sea level. It leads directly to the border of Afghanistan at Chaman which is 153 kms away from Quetta. The train passes through the longest tunnel of the sub-continent. The scenery is breath-taking as here as it is at Bolan Pass.
The entire population of Kharwari Baba and for that matter of the entire Ziarat, migrates to Harnai in extreme winter. Harnai Pass, about hours drive from Loralai, is just as spectacular as the Khyber Pass near Peshawar.
