Lough Erne is the name of two connected lakes in County Fermanagh, Northern Ireland. It is the second-biggest lake system in Northern Ireland and Ulster, and the fourth biggest in Ireland. The lakes are widened sections of the River Erne, which flows north and then curves west into the Atlantic.
The smaller southern lake is called the Upper Lough as it is higher up the river.
The bigger northern lake is called the Lower Lough or Broad Lough.
The town of Enniskillen lies on the short stretch of river between the lakes. The lake has more than 150 islands, along with many coves and inlets.
