The ancient territory of Inishowen is now a barony of the County of Donegal, and in it is Malin Head, the most northern point of Ireland. Inishowens length is 26 miles, and greatest breadth about 25 miles. It comprises an area of 197,860 statute acres, or about 309 square miles.

On its northern shores is the Atlantic Ocean; Lough Foyle forms its eastern boundary, and Lough Swilly its western. It is connected with the mainland on the south, and is, therefore, not an inis, or island, as its name implies, but a peninsula. Its southern limit, however, is not so well defined; some say it was formed by a line drawn from Lough Swilly through the present town of Manorcunningham to Carrigans, on the river Foyle; while others suppose it did not extend so far south.

Regarding its southern boundary we learn, by the Ordnance Survey that, "about half the parish of Templemore, or what is generally called the northern liberties of Londonderry, was comprised in Inishowen, before the formation of the County of Londonderry, as is evident from an inquisition taken in Derry in the seventh year of the reign of James I., from which it appears that a jury composed of resident English and ancient Irish natives, of the principal septs of the district, 'did upon their oaths find and present that the ancient and known meares of the country of Inishowen, alias O'Dogherties

Leaving out the promontory of Malin Head, lnishowen has something of a triangular shape, with the base turned to the north. A ridge of mountains runs along each of the sides of this triangle, leaving a comparatively narrow margin on the cast and west sloping down to the water.

The western chain is the highest and most precipitous, and includes the Fahan, Desertegney and Clonmany mountains, and terminates at Culdaff. On the cast are the Iskaheen and Moville mountains, sloping off gently to lnishowen Head.

The north is enclosed by the Glengad and Malin ridge, running from east to west, and terminating at Pollin Strand. This chain is not quite continuous, a link having apparently been snapped by some violent convulsion of nature, separating the Isle of Doagh from Malin, with which there is sufficient reason to believe it was once connected, and permitting the waters of the Atlantic to enter in the breach, and to form the gulf or rather inland lake of Strabreagy. From the apex of the triangle above-named a central range runs northward, with spurs that shoot off cast and west, towards Glenaganon on the one hand, and the high lands of Cooteross and the Clonmany mountains


A set out tourist route taking in the main areas of interest is sign posted and is 100 miles around the peninsula.
