About

Y Groeslon ward lies in the southern part of Gwynedd, encompassing a largely rural landscape. The area is centred around the village of Groeslon itself, situated along the A487 road between Caernarfon and Penygroes. The ward's terrain includes agricultural land and lower slopes of the Eifionydd region, with views towards the mountains of Snowdonia to the east. Settlement is primarily dispersed, with smaller hamlets and farms spread across the ward's boundaries.

The local economy has traditional roots in agriculture and slate quarrying, with several former quarry sites within the area. Community life focuses on the village school, chapels, and local services. The ward is traversed by the Nantlle Railway path, a leisure route following the trackbed of an historic railway that once served the slate industry, offering quiet walking and cycling through the countryside.
