Geography in County Donegal


Geography in County Donegal

The Donegal mainland coastline is the longest in the country at 1,134km and constitutes over 17% of the total national coastline. The main inlet is Lough Swilly which extends 30km inland from the north coast to Letterkenny. The county consists chiefly of low mountains, with a deeply indented coastline forming natural loughs. The mountains (more famously known as the "Hills of Donegal") consist of two main ranges, the Derryveagh Mountains in the north and the Bluestack Mountains in the south. Mount Errigal, at some 750 metres, is the highest peak. The Slieve League cliffs are the highest sea cliffs in Europe and Malin Head, in the Inishowen Peninsula, is the most northernly point on the island of Ireland.
