Newcastle is the quintessential gateway to the Mourne Mountains. This vibrant seaside town of 7,700 residents (swelling considerably in summer) sits where three rivers—the Shimna, Burren, and Tullybranigan—converge at the foot of Slieve Donard, Northern Ireland's highest peak at 850 metres.

A Town of Character
Named after the 1588 MacGinnis castle that once stood at the mouth of the Shimna River, Newcastle combines the charm of a Victorian seaside resort with the energy of an outdoor adventure hub. The golden beach, backed by a traditional promenade with amusement arcades and ice cream parlours, offers classic seaside fun, while the mountains beckon hikers and adventurers just moments away.

From world-class golf to dramatic mountain hikes, Newcastle serves it all.
