About

Sully ward sits along the Bristol Channel coastline, characterised by its residential areas and coastal paths. The settlement includes the village of Sully and the larger community of Barry's western suburbs, featuring a mix of housing developments and local amenities. The area is defined by its proximity to the water, with several beaches and rocky outcrops accessible to the public.

A notable landmark is Sully Island, a tidal island reachable on foot across a causeway during low tide. The surrounding mudflats and saltmarsh are part of a designated Site of Special Scientific Interest. Inland, the ward contains playing fields and green spaces that separate its neighbourhoods, maintaining a distinct layout from the more urban centre of Barry to the east.
