It connects to the larger town of Alexandria and to the smaller village of Jamestown, both of which are located to its south. To the east of the town lies the major local authority housing scheme in the area known as 'The Haldane'. Balloch railway station is a terminus of the North Clyde electric train service from Glasgow.

Bonhill is a town in the Vale of Leven area of West Dunbartonshire. It sits on the Eastern bank of the River Leven opposite the larger town of Alexandria. The town rapidly expanded in the 1960s and 1970's when many residents of Glasgow were moved there when the old slums and tenements were demolished. This process was known as the "Glasgow overspill". The new council run housing schemes were characterised by a high incidence of poverty and unemployment, but the town has changed somewhat with the addition of private housing schemes (such as the Strathleven Park estate) from the late 1970s onwards. Due to a lack of planning when the new housing was built, Bonhill suffers from a lack of amenities. Most of these are located mainly in Alexandria, just across the river Leven and Dumbarton, two miles to the South. It serves as a commuter town to Dumbarton and beyond. According to the 2001 National Census, Bonhill's population is 9,574.
