Rostrevor Forest Slievemartin Trail — Mourne

Embark on the Rostrevor Forest Slievemartin Trail, a moderate hike spanning 4.9 miles (7.9 km) with an elevation gain of 1405 feet (428 metres), typically taking around 2 hours and 43 minutes to complete. As you ascend, you will pass through ancient oakwood and coniferous forests, eventually reaching the summit of Slieve Martin. From this high point, you are rewarded with panoramic views of Carlingford Lough, the village of Rostrevor, and across to Carlingford and O'Meath. The paths are generally accessible, though some sections are steep and stony, requiring sturdy footwear. You will find the terrain varied, moving from forest roads to well-trodden paths and occasionally rough moorland.

Planning your visit is straightforward, as the route is popular and offers convenient parking, especially at the upper car park near Cloughmore. The trail is suitable for those with good fitness, and while there are steep ascents, particularly towards Slieve Martin, the overall experience is rewarding. Be prepared for potentially strong winds at the summit. This trail is a great option for a day out, offering both a good workout and stunning scenery.

This trail is notable for its diverse features, including the impressive Cloughmore Stone, a 50-ton erratic granite boulder with a legendary connection to Finn McCool. You can also discover Fiddler's Green, a serene spot perfect for a break, and the 200-year-old Invisible Tree, a local symbol for environmental protection. The area's profound beauty, with its dramatic landscapes and ancient woodlands, is even said to have inspired C.S. Lewis's Narnia. On clear days, you can see the Irish Sea and other Mourne peaks, making this a truly memorable hike.
