Castle ward is a rural area within Mid and East Antrim, characterised by agricultural land and small settlements. The landscape is dominated by rolling fields and low hills, with a network of narrow country roads connecting dispersed farms and homes. The ward includes the village of Ballynure and extends towards the larger town of Ballyclare, though it maintains a distinctly separate, quiet character. This is a part of the borough where farming remains a central part of the local economy and community life.
A very specific feature of the area is the presence of the Six Mile Water River, which flows through the ward's southern parts. The river valley adds a distinct topography and supports local wildlife. The ward's eastern boundary is marked by the presence of the Belfast International Airport, whose perimeter lies within the area, creating a notable contrast between pastoral scenery and modern infrastructure. Residential development is primarily concentrated in the villages, with much of the surrounding land used for pasture and crop cultivation.
