Hiking

Embark on a challenging 10.7-mile (17.2 km) hike that takes you from Bloody Bridge, along a rocky river path, through an old quarry, and up to the summit of Slieve Donard. This difficult route, typically taking 6 hours and 20 minutes, involves a significant 3634 feet (1108 metres) of elevation gain. You will experience varied terrain, from marshy sections requiring waterproof footwear to steep climbs and descents, especially as you approach Northern Ireland's highest peak. On a clear day, the panorama from Slieve Donard is superb, extending to the Isle of Man and Scotland. The trail also guides you through Hare's Gap, a dramatic mountain pass offering unique views of the surrounding landscape. You will follow sections of the historic Mourne Wall, which weaves naturally through the mountains. This journey promises spectacular scenery and a deep immersion in the Mourne Mountains. If you are looking for a strenuous adventure with rewarding vistas, this route is for you. You will need a high level of fitness and experience for this demanding journey. The path from Bloody Bridge is initially rocky, then joins a gravel road through a quarry before becoming a dirt trail. The ascent to Slieve Donard is particularly steep after reaching the Mourne Wall, requiring careful footwork. Hare's Gap, while having a well-maintained path when accessed via Trassey's Track, is still fairly steep and rocky. This combined route is notable for several key features, including the ascent of Slieve Donard, Northern Ireland's highest mountain, offering unparalleled summit views. A significant portion of the hike follows the historic Mourne Wall, a 31-kilometer (19-mile) dry-stone wall built between 1904 and 1922 to enclose the Silent Valley Reservoir catchment area. Hare's Gap is a historically significant point, once serving as an exit for smuggled goods carried through the mountains along the Brandy Pad. The trail transitions from coastal beginnings at Bloody Bridge, alongside a river, through old quarry areas, and onto exposed mountain slopes, showcasing the diverse beauty of the Mournes. Completing this rigorous combination of routes is a significant achievement, rewarding hikers with a deep immersion in the raw beauty and history of the Mourne Mountains.

The Mourne Wall

Highlight • Monument

Taking almost 20 years to build, the 19-mile (31 km) Mourne Wall runs across the principal summits of the Mourne Mountains. It was built to keep livestock from contaiminating the Silent Valley Reservoir and passes over no less than 15 peaks in the Mournes.

Its perimeter has given rise to the Mourne Wall Challenge where hikers complete a full circuit of the wall, visiting seven of Northern Ireland's ten highest mountains and conquering over 8,000 feet (2,400 metres) of elevation gain.

Slieve Commedagh Summit

Highlight • Summit

Slieve Commedagh, at 767 meters, is the second-highest peak in the Mourne Mountains and a rewarding climb for any hiker. Its summit offers sweeping views across the Mournes and out to the Irish Sea, a reminder of how close these mountains sit to the coast. The ascent is steep and demanding, often over pathless ground, but never overly technical in good weather.
