County Down - Geography

Geography

Down contains two significant peninsulas: Ards Peninsula and Lecale peninsula.

The county has a coastline along Belfast Lough to the north and Carlingford Lough to the south (both of which have access to the sea). Strangford Lough lies between the Ards Peninsula and the mainland. Down also contains part of the shore of Lough Neagh. Smaller loughs include Lough Island Reavy.

The River Lagan forms most of the border with County Antrim. The River Bann also flows through the southwestern areas of the county. Other rivers include the Clanrye and Quoile.

There are several islands off the Down coast: Mew Island, Light House Island and the Copeland Islands, all of which lie to the north of the Ards Peninsula. Gunn Island lies off the Lecale coast. In addition there are a large number of small islands in Strangford Lough.

County Down is where, in the words of the famous song by Percy French, "The mountains of Mourne sweep down to the sea", and the granite Mourne Mountains continue to be renowned for their beauty. Slieve Donard, at 849 m (2,785 ft), is the highest peak in the Mournes and in Northern Ireland. Another important peak is Slieve Croob, at 534 m (1,752 ft), the source of the River Lagan.
