The town is west of the seaside town of Herne Bay, north-east of the town of Faversham and north of the city of Canterbury; several small villages lie in between. The suburbs/villages of Tankerton, Swalecliffe and Chestfield are at the eastern end of the town, Seasalter at the west, and South Street at the south. Chestfield has its own parish council. An area of protected woodland and grassland called Duncan Down lies to the south-east.
