About

Llanllyfni is a rural ward situated in the heart of the Llŷn Peninsula. Its landscape is dominated by the prominent peak of Mynydd Graig Goch to the west and the broader slopes of Mynydd Nefyn to the north. The area is characterised by scattered farms, small settlements, and the Afon Llyfni river which flows through the valley. Agriculture remains a central part of the local economy and community life here.

The ward includes the village of Carmel and is traversed by the B4417 road. A notable feature is the presence of the old Nantlle Railway trackbed, a remnant of the area's slate quarrying history. The surrounding land is used for both pasture and forestry, creating a patchwork of fields and woodland. The community maintains a strong Welsh cultural identity, with the Welsh language widely spoken in daily life.
