Mullaghmore

In July and August, the sleepy fishing village of Mullaghmore becomes congested with tourists. Its main attractions: a 3-km-long (2-mile-long) sandy beach, and the turreted, fairy-tale Classie Bawn—the late Lord Louis Mountbatten's home. (He, his grandson, and a local boy were killed when the IRA blew up his boat in the bay in 1979; the castle is still privately owned and not open to the public.) A short drive along the headland is punctuated by unobstructed views beyond the rocky coastline out over Donegal Bay. When the weather is fair, you can see all the way across to St. John's Point and Drumanoo Head in Donegal.
