The parish boundary, to the south and east, lies close to the village, and follows the River Gwash. Just west of the B1081 bridge over the Gwash, it borders Tinwell. Just to the west of Ingthorpe (part of Tinwell), it borders Tickencote. The parish boundary crosses the A1 at the turn off for the village. The boundary then follows the A1 north, along the next hedge to the east (a field's width). It passes to the east of Tickencote Warren, and at Exeter Gorse it briefly borders Horn, then meets Pickworth. It passes to the south of Eayres Lodge, includes Woodhead, crossing "Pickworth Road" south of Taylor's Farm. West of Tolethorpe Oaks, it briefly meets Ryhall, then borders Little Casterton southwards, passing Frith Farm to the west and broadly follows the Danelaw Way. North of Little Casterton village, the boundary meets the Gwash.
