Nestled in County Down in Northern Ireland, the Mourne Mountains are a paradise for hikers, nature lovers, and adventurers. Designated as an Area of Outstanding Natural Beauty (AONB), the Mournes offer dramatic peaks, peaceful valleys, tranquil lakes, and a network of well-maintained trails. With over 30 marked hiking routes ranging from easy walks to challenging climbs, this region stands as the most prominent mountain range in Northern Ireland.

A Landscape Dominated by Granite Peaks
The Mourne Mountains are famed for their rugged beauty and distinctive granite peaks. Slieve Donard, at 850 metres, is the highest point in Northern Ireland and a popular summit for both seasoned climbers and enthusiastic amateurs. Other major peaks include Slieve Binnian, Slieve Bearnagh, and Slieve Meelmore, all offering panoramic views across the Irish Sea, nearby valleys, and even Scotland on a clear day.
The Mourne Wall – A Miniature Great Wall of Ireland
One of the most striking man-made features of the Mournes is the Mourne Wall, a 35-kilometre (22-mile) dry-stone wall built between 1904 and 1922. Constructed to enclose the catchment area of the Silent Valley Reservoir, the wall crosses 15 of the highest mountains in the range. It winds over peaks and across valleys with such purpose and precision that it could be likened to a miniature version of the Great Wall of China.
Many hikers choose to follow segments of the wall as a natural guide through the hills, and some even take on the full Mourne Wall Challenge Walk, a strenuous but rewarding one-day trek that covers the entire route.

Trails for Every Type of Hiker
The Mournes boast over 30 marked trails, offering everything from gentle family walks to intense mountain hikes. Some of the most popular routes include:
- The Glen River Trail to Slieve Donard begins at Donard Park in Newcastle and ascends steadily through forest and mountain terrain.
- The Binnian Loop Walk – a moderate to strenuous loop with breathtaking views over the Silent Valley and Annalong Valley.
- The Trassey Track to Slieve Bearnagh – known for its dramatic tors and sweeping views.
- The Ott Track to Slieve Loughshannagh and Doan – a less crowded but spectacular path through peatland and granite scenery.
The variety and quality of trails make the Mourne Mountains an ideal year-round destination for hikers of all levels.
Silent Valley and the Lakes of the Mournes
The Silent Valley Reservoir, set deep within the mountains, is one of the area’s most serene and scenic destinations. Managed by Northern Ireland Water, this reservoir not only supplies water to the region but also provides a peaceful setting for walking trails, picnics, and nature photography.
Nearby, Ben Crom Reservoir and Lough Shannagh offer additional points of interest for those seeking quiet retreats surrounded by nature.
