The Dyfi hills (sometimes anglicised to Dovey hills) are a range situated in the southernmost area of Snowdonia, bounded by the River Dyfi on the east and south sides, by the Afon Dulas on the west and the Afon Cerist to the north. They lie to the west of the Aran Fawddwy range, north-east of the Tarren y Gesail range and are a subgroup of the Cadair Idris group.
The highest peaks of the Dyfi hills are Maesglase (2,218 feet (676 m)), Waun-oer (2,200 feet (670 m)) and Cribin Fawr (2,162 feet (659 m)) which lie at the north of the range. Further south the peaks are lower and the hills more gently rounded.
