A narrow sea lough with significant expanses of mudflat and saltmarsh, and several small rock and shingle islands. Mountains surround the lough. This is a cross-border site, the southern shore lying in County Louth in the Republic of Ireland (IBA 122). The stated area of 4,660 ha covers the entire site on both sides of the border, but other data given here (habitats, land-use, threats and birds) are specific to the UK side. The IBA is important for breeding terns and wintering waterbirds. Branta bernicla are from the Canadian/Greenland breeding population of the hrota subspecies.
