Portnablagh (Irish: Port na Bláiche, meaning, depending on translation, either ‘port of the flowers’ or ‘harbour of the buttermilk’, possibly from the rough seas in the area) is a small village in County Donegal in Ulster, Ireland. Portnablagh (also written in English as Port-na-Blagh) is located on Donegal’s North West coast, specifically the west side of Sheephaven Bay.
Portnablagh, along with neighbouring Dunfanaghy, is known for its beaches and harbour. It attracts tourists, mostly from Northern Ireland, every summer.
The small harbour is protected on 3 sides and has a relatively short slipway which is used by fishing and pleasure boat owners, particularly during summer months. It provides access for boat owners to beaches in Sheephaven Bay, many of which are only accessible on foot or by sea.
