Penrhyn Bay is a small town located on the coast of Conwy County, North Wales. Originally a small farming community, the town relied heavily on the limestone quarry which ceased in 1936. During the 20th century Penrhyn Bay expanded rapidly to become a desirable suburb of Llandudno.
The Little Orme stands above Penrhyn Bay and presents excellent opportunities for walking and nature study, and its cliffs and caves are a major challenge to experienced climbers.
Rhiwledyn is the Welsh name for The Little Orme and is home to a site of special scientific interest and about 12 acres forms the Rhiwledyn Nature Reserve, which is managed by the North Wales Wildlife Trust. The nearby Angel Bay, Porth Dyniewaid in Welsh, is a picturesque location with views along the coast. On warm sunny days seals can often be seen basking in the cove of the bay.
The oldest building in the town is the Penrhyn Old Hall, dating from the early 15th century. In the grounds of the hall are the ruins of the medieval chapel of the Blessed Virgin Mary of Penrhyn, last used for worship c1930. The hall now serves as a pub and restaurant.
