County Donegal

County Donegal is a largely Irish-speaking region bordering the Atlantic Ocean in northwestern Ireland. It's made up of castles, rugged coastline and mountains such as the quartzite Mount Errigal. Glenveagh National Park, once a private estate, encompasses forests, lakes and bogland in the Derryveagh Mountains. Its 1870s manor house, the Scottish Baronial-style Glenveagh Castle, is known for its Victorian gardens.
