The Mourne Wall is one of the most iconic landmarks of the Mourne Mountains, stretching for 35 kilometers across 15 summits. Built by hand in the early 20th century to enclose the Silent Valley Reservoir catchment area, it’s an impressive feat of craftsmanship and endurance.

Today, hikers crossing its path are struck not only by its scale and history but also by the way it weaves naturally into the dramatic mountain landscape. Following the wall offers some of the best ridge walks in the Mournes, making it both a cultural treasure and a perfect guide for exploring these rugged peaks.

The Mourne Wall is a 22-mile-long, 1.5m high stone wall that stretches through the beautiful Mourne Mountains. It was built to stop livestock from contaminating water supplies, and took almost 20 years to complete!
