Rosguill Peninsula, County Donegal
Rosguill Peninsula juts out into the Atlantic Ocean between Sheephaven and Mulroy bays. The simplest way to see it is to follow the 11km Atlantic Drive, a circular route which skirts the clifftops at the tip of the headland.
Doe Castle, north of Creeslough village, is worth a visit as much of its setting on a promontory over-looking Sheephaven Bay as for its architectural or historical interest. Even so, it is still a substantial ruin – the remains of a castle erected in the 16th century by the MacSweeneys, a family of Scottish mercinaries.
Rosguill Peninsula and Doe Castle is a must see on your Ireland tours.
