To the west, the parish boundary meets Braceborough and Wilsthorpe to the north, passing through Banthorpe Lodge, crossing the East Coast Main Line, then following the West Glen River through Shillingthorpe Park. Close to the village near Greatford Hall, the boundary passes north, crossing the road to Carlby. It follows part of the Macmillan Way (which passes straight through the parish, broadly following the Glen) near some coppices. It rejoins the West Glen River, crossing the road to Wilsthorpe. East of Fletland Mill, it meets Thurlby (Obthorpe).
