Carlingford Lough Ramsar Site is a vital coastal wetland straddling the border of Northern Ireland and the Republic of Ireland, renowned for its rich biodiversity and scenic estuarine environment offering excellent birdwatching and shoreline exploration.
Carlingford Lough Ramsar Site encompasses the tidal estuary of Carlingford Lough, situated on the east coast of Ireland, forming a natural border between County Louth in the Republic of Ireland and County Down in Northern Ireland. This internationally recognized wetland covers approximately 4000 hectares combining intertidal mudflats, saltmarshes, rocky shores, and freshwater habitats, which together support a vast array of wildlife. The Lough is a key stopover for migratory waterbirds such as Brent Geese, Shelduck, and Wigeon, alongside populations of wildfowl and waders, contributing to its designation under the Ramsar Convention on Wetlands. Ecologically, it sustains habitats for rare plant species and marine life, including shellfish beds and eelgrass beds vital to the coastal ecosystem’s health. Historic features around the Lough include the medieval Carlingford town with its preserved heritage and nearby coastal castles highlighting the area's cultural significance. Outdoor enthusiasts are drawn to the site for birdwatching, kayaking, fishing, and coastal hiking along trails like the Carlingford Lough Greenway. Its gentle water and varied shorelines also offer tranquil opportunities for photography, nature study, and peaceful shoreline walks. Management of the site involves both Republic of Ireland and Northern Ireland conservation bodies, ensuring protection of this ecologically sensitive and scenic area, while facilitating sustainable public enjoyment and environmental education.
