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.

This historic 10th century tower stands in idyllic countryside and offers a fascinating insight into Ireland's early Christian history. Access is via narrow country lanes; there is a small car park but it is not always well signposted. The tower is on private farmland but access is usually permitted.

The route takes you along the Silent Valley Reservoir on a well-developed, asphalt road that is also suitable for less experienced drivers. However, it can be slippery in wet weather, so caution is advised. A special highlight is the impressive dam wall of the Ben Crom Reservoir, which blends harmoniously into the surrounding mountain landscape. Please note, however, that access to the park is subject to a fee.
