Three east-west routes pass quite near to the middle of the parish and are aligned east-west: the M20 motorway, the A20 single carriageway road and the High Speed 1 railway line connecting to the Channel Tunnel. Most of the development is residential and all of the neighbourhoods are north of the motorway. The parish has many headwaters to the East Stour which bounds Smeeth to its south. The far northern borders are contiguous with Brabourne Lees and link into its main 'village street' directly; this is also where most of the buffer land is woodland.
