Baldoyle Estuary

Baldoyle Estuary is a 195-hectare coastal nature reserve located on the east coast of Fingal in north County Dublin, forming part of the larger Baldoyle Bay between the communities of Portmarnock and Baldoyle. This internationally important wetland encompasses the estuaries of the Sluice River and Mayne River, featuring a diverse mosaic of saltmarsh, mudflats, and sand habitats. Designated as a Statutory Nature Reserve in 1988, a Special Area of Conservation, a Special Protection Area, and a Ramsar Wetland of International Importance, Baldoyle Estuary represents one of Dublin's most significant coastal wildlife sites and forms part of the Dublin Bay Biosphere Reserve, providing critical habitat for thousands of wintering waterbirds within reach of Ireland's capital city.
