Rostrevor ward sits on the western shore of Carlingford Lough, with the Mourne Mountains rising directly behind it. The area includes the village of Rostrevor itself, a settlement known for its long, tree-lined square. The landscape is defined by the transition from the lough's tidal waters to the forested slopes of Slieve Martin, part of the broader Mourne range.
The natural setting is central, with Kilbroney Park offering riverside walks through ancient yew trees. The area is historically linked to the granite-quarrying industry that supplied material for local buildings and beyond. Rostrevor's position provides direct views across the narrow lough to the Cooley Peninsula in the Republic of Ireland.
