Seion lies in Gwynedd between the Menai Strait and Snowdonia's foothills, just off the A4086 linking Caernarfon and Llanberis. Most reach it via A55 Junction 11 at Bangor, then the A4087. The village serves both Bangor commuters and Snowdonia tourists, with over 30 EV charging points nearby. Former quarry workers' cottages line its traditional stone-walled lanes.
