North West Wales (Welsh: Gogledd-Orllewin Cymru) is an area or region of Wales, commonly defined as a grouping of the principal areas of Conwy County Borough, Gwynedd and the Isle of Anglesey in the north-west of the country. These principal areas make up the entire preserved county of Gwynedd, and parts of Clwyd. It is bordered by Denbighshire, in North East Wales to the east, Powys, and Ceredigion in Mid Wales to the south, and the Irish sea to the north and west (as Cardigan Bay). It is the more mountainous, rural, and sparsely populated part of the north Wales geographic region.
Settlements include: Bangor, Caernarfon, Colwyn Bay, Holyhead, Llandudno, and Pwllheli. The port of Holyhead serves as the major sea link between Wales and Ireland. Snowdonia National Park is located wholly in the area, hosting Snowdon, the largest peak in British Isles excluding the Scottish Highlands. The area also hosts AONBs (Area of Outstanding Natural Beauty) in the LlÅ·n Peninsula and Isle of Anglesey, and the Castles and Town Walls of King Edward UNESCO World Heritage Site.
