Lough Neagh (pronounced 'nay') is the largest freshwater lake in Britain and Ireland, big enough to swallow the city of Birmingham (West Midlands, UK, or Alabama, USA – either one would fit). Though vast (around 32km long and 16km wide), the lough is relatively shallow – never more than 9m deep – and is an important habitat for waterfowl. Its waters are home to the pollan, a freshwater herring found only in Ireland, and the dollaghan, a subspecies of trout unique to Lough Neagh.
Connected to the sea by the River Bann, the lough has been a vital waterway and food source since prehistoric times, and is still home to Europe's largest eel fishery. The lough's main points of access – with the best views – include Oxford Island in the south, Antrim town on the eastern shore, and Ardboe in the west.
