Hiking
Embark on a moderate hike up Slieve Donard, Northern Ireland's highest peak, covering 6.1 miles (9.7 km) with a significant elevation gain of 2619 feet (798 metres). This route, typically completed in about 3 hours and 55 minutes, offers a varied ascent. You begin alongside the Bloody Bridge River, where you'll find charming rock pools and small waterfalls. As you climb higher, the path leads you past an old granite quarry, transitioning to more rugged terrain. The reward for your effort is the expansive vista from the summit, providing clear views across the Mourne Mountains and even to the Isle of Man on a good day.
To start this adventure, head to the Bloody Bridge car park, which serves as the trailhead. Be prepared for the demanding nature of the path, as it includes rocky sections, areas of loose peat, and can become boggy, especially after rainfall. The weather in the Mournes is known for its sudden changes, so always pack for strong winds, rain, or even snow, particularly at higher elevations. It's wise to check the forecast and plan an early start to allow ample time for the ascent and descent.
This trail offers a unique perspective on the Mourne Wall, an impressive dry-stone wall that stretches for 22 miles across the peaks of the Mourne Mountains. You will encounter this historic structure during the latter part of your climb, serving as a constant companion and a testament to early 20th-century engineering. The route provides a deep immersion into the Mourne Area of Outstanding Natural Beauty, showcasing its rugged beauty and diverse ecosystems.

The trail officially starts from the Bloody Bridge car park. This is the primary access point for the route, and parking is available there. It's advisable to arrive early, especially on weekends, as parking can fill up quickly.
The terrain is varied and can be demanding. It begins with rocky sections along the Bloody Bridge River, transitioning to a stony, old quarry track. Higher up, you'll encounter very rocky ground with loose peat and potentially boggy sections, especially after rain. The final ascent to the summit is steep and often follows the Mourne Wall on stony, potentially slippery ground.
You'll encounter several interesting features. The historic Bloody Bridge itself is a point of interest at the start. As you ascend, you'll pass a disused granite quarry with a pretty waterfall. A significant part of the climb follows the iconic Mourne Wall. The highlight is the Summit of Slieve Donard, offering panoramic views of the Mourne Mountains, the Annalong Valley, and on clear days, even the Wicklow Mountains and the Isle of Man. The initial stretch also offers the picturesque Bloody Bridge River Walk with its rock pools.
This trail is generally considered challenging and requires a good level of fitness. While some sources grade it as 'moderate', others classify it as 'difficult' due to the significant elevation gain, varied terrain, and steep sections. It's not recommended for absolute beginners, especially those unfamiliar with mountain hiking.
Yes, this specific route is designed as a looped trail, allowing you to experience different scenery on the ascent and descent without retracing your steps entirely.
While dogs are generally permitted in the Mourne Mountains, it's crucial to keep them on a lead, especially due to livestock grazing and ground-nesting birds. The terrain can be challenging for some dogs, with rocky and boggy sections, and the Mourne Wall can be an obstacle. Always ensure your dog is well-behaved and capable of handling the conditions.
Spring and summer (May to September) generally offer the most favorable conditions with longer daylight hours and milder weather. However, the weather in the Mournes can change suddenly at any time of year, so always be prepared for strong winds, rain, or even snow at higher elevations. Autumn can offer beautiful colors but also brings shorter days and potentially wetter conditions.

Yes, the route intersects with significant sections of other well-known paths. A substantial part of the ascent follows the iconic Mourne Wall, and the trail also connects with sections of the historic Brandy Pad, an old smuggler's path.
Given the challenging terrain and unpredictable mountain weather, it's essential to be well-prepared. Wear sturdy hiking boots with good ankle support, and dress in layers, including waterproof and windproof outer shells. Bring plenty of water, high-energy snacks, a map and compass (or a fully charged GPS device), a first-aid kit, and a headlamp, even if you plan to finish before dark. Sun protection is also advisable.
