Pen Y Boncyn Trefeilw rises to approximately 305 metres and is part of the undulating landscape of the Eryri (Snowdonia) mountain range. Its name, meaning "Head of the Trefeilw Rocks," suggests a connection to local Welsh place-name traditions reflecting the area's rugged terrain. It contributes to the regional identity and topographic character of Gwynedd.
