Caernarfon Bay (occasionally Caernarvon Bay)[1] is an inlet of the Irish Sea defined by the Llŷn peninsula and Anglesey.
The gentle coastline surrounding it is home to villages including Nefyn, Pistyll, Trefor, Llithfaen , and Clynnog Fawr on the mainland, and Aberffraw, Llanddwyn and Rhosneigr on Anglesey.
The Menai Strait heads north east to link the bay to Conwy Bay.
