Aran Fawddwy, which is only 9 metres (30 ft) short of being a member of the Welsh 3000s, is the highest peak in the Aran mountain range and the 16th highest summit in Wales. The other two Marilyns in this range are Glasgwm and Esgeiriau Gwynion.[4] It is the highest British mountain south of Snowdon and is the principal summit of the predominant southwest-northeast ridge between Dolgellau and Bala, southern Snowdonia, a ridge that continues westwards as Cadair Idris.
