Conwy County Borough (Welsh: Bwrdeistref Sirol Conwy) is a county borough in the north of Wales. It borders Gwynedd to the west and south and Denbighshire to the east. The largest settlement is Colwyn Bay, and Conwy is the administrative centre.
Conwy has an area of 435 square miles (1,130 km2) and a population of 114,800, making it sparsely populated. The population is concentrated along the coast, along which are several seaside resorts and the county's largest towns: Colwyn Bay (34,284), Llandudno (20,701), and Conwy (14,753). Inland is much less populous, and the only town is Llanrwst (3,323).
The geography of Conwy is shaped by the River Conwy, which forms a wide valley down the western half of the county, bordered by the Denbigh Moors to the east and the mountains of Snowdonia National Park to the west. The River Elwy, a tributary of the Clwyd, drains the eastern half of the moors. The Conwy forms a wide estuary as it reaches the coast, which has by wide, sandy beaches and the limestone headlands of the Great Orme and the Little Orme. The highest peak within the county is Glyder Fawr, at 1,001 metres (3,284 ft), which is on the boundary with Gwynedd and is the sixth-highest summit in Wales. Around Betws-y-Coed is the Gwydir Forest, which is mainly given over to plantations. There are several reservoirs in the valleys, the largest of which is Llyn Brenig, which has an area of 3.7 square kilometres (1.4 sq mi) and extends into Denbighshire.
