Aghadowey ward lies in the fertile lowlands of the Causeway Coast and Glens, centred around the village of the same name along the A54 road. The landscape is primarily agricultural, characterised by rolling fields and hedgerows, with the River Bann forming a significant part of its eastern boundary. This rural setting supports farming as a central activity, with a pattern of small settlements and dispersed dwellings spread across the ward's territory.
The area is historically connected to linen production, with the former mill chimney of Aghadowey a local landmark. The ward includes the smaller settlement of Knockantern, and its community facilities are typical of a rural district. The surrounding land is drained by tributaries feeding into the Bann, contributing to the area's quiet, working countryside character distinct from the busier coastal zones to the north.
