As part of the Republic of Ireland, Killybegs is Ireland's largest and most important fishing port. This small town of approximately 1,300 residents has welcomed mariners to its sheltered deep-water harbour for centuries. The town's name derives from the Irish "Na Cealla Beaga" meaning "the small churches," a reference to early Christian monastic cells that once stood here. County Donegal lies in the far northwest corner of Ireland and is noted for the beauty of its rugged coastline and heather-covered moors. The magnificent barren inland mountains form part of the same geological structure as the Scottish Highlands. Donegal is the second largest Gaeltacht (Irish-speaking) region in Ireland. The county was named number one in National Geographic Traveller's 'Cool List' for 2017, praised for its dramatic sea stacks, pristine beaches, and remote islands. The currency is the Euro (€) and ATMs are available at Bank of Ireland, Ulster Bank, and the Super Valu supermarket on Donegal Road.
