Rhinog Fach is a
mountain in
Snowdonia,
North Wales and forms part of the
Rhinogydd. Technically, Rhinog Fach is a subsidiary summit of Y Llethr, missing Marilyn status by 3m. Thus making it a sub
Marilyn along with
Diffwys. To the north lies its higher cousin
Rhinog Fawr, separated by the shapely pass of Blwch Drws Ardudwy.
