It is situated in the eastern part of the county, bounded on the north by the hundred of Skenfrith; on the east by Gloucestershire's St Briavels Hundred; on the south by the hundred of Caldicot; on the south-west by the hundred of Usk and on the north-west by the hundred of Abergavenny.
This hundred is less mountainous than that of Usk to the south and watered with fewer streams than any hundred in the county. It is however a fine fertile district abounding in rich arable and pasture lands and pleasingly diversified with gentle elevations and depressions with occasional valleys and hills. It is the least populous of Monmouthshire's hundreds, with a population of 7,980.
It contains the following ancient parishes:
- Bettws Newydd
- Chapel Hill
- Grace Dieu Park (ex. par.)
- Llanarth (Clytha hamlet)*
