About Rhinog Fach
Rhinog Fach is technically a subsidiary summit of Y Llethr, though its drop is enough to make it a Marilyn in its own right. Bwlch Drws Ardudwy, a shapely pass, separates it from the higher Rhinog Fawr to the north.
Despite being lower than Y Llethr, whose top is grassy and unremarkable, Rhinog Fach is often reckoned the true king of the Rhinogydd on the strength of its rocky peak.
