Where the Bloody Bridge River cascades from Slieve Donard to the sea, nature carves a dramatic playground of granite boulders, roaring waterfalls, and deep, inviting pools. A hotspot for thrill-seekers, this rugged stretch offers world-class bouldering and coasteering—but only under the guidance of a qualified instructor, as the raw power of the water demands respect.

Prefer to keep your feet on solid ground? The 1-mile linear trail along the rocky coastline serves up breathtaking views of the Irish Sea, making it the perfect scenic stroll after a refreshing wild swim in the river's pools.
