Lower Lough Erne
Lower Lough Erne is a more open expanse of water than the Upper Lough, with its 90-odd islands clustered mainly in the southern reaches. In early Christian times, when overland travel was difficult, Lough Erne was an important highway between the Donegal coast and inland Leitrim, and there are many ancient religious sites and other antiquities dotted around its shores.
Upper Lough Erne
Upper Lough Erne is not so much a lake as a watery maze of more than 150 islands, inlets, reedy bays and meandering backwaters. Bird life is abundant: flocks of whooper swan and goldeneye overwinter here; great crested grebes nest in the spring; and you'll find Ireland's biggest heronry in a 400-year-old oak grove on the island of Inishfendra, just south of Crom Estate.
