Hiking

Embark on a challenging yet rewarding hike to Hare's Gap and Slieve Bearnagh from Trassey Car Park, covering 6.0 miles (9.6 km) with a significant 1688 feet (514 metres) of elevation gain. This moderate route, typically taking around 3 hours and 21 minutes, leads you through varied terrain, starting on a gravel forest road before transitioning to rougher off-road paths, boulder fields, and steep, rocky ascents. As you climb, you'll pass through Clonachullion Forest and witness the dramatic tors of Slieve Bearnagh, eventually reaching Hare's Gap, a stunning mountain pass offering panoramic views across the Mournes.

This trail demands a good level of fitness and sure-footedness, especially as you navigate the steeper sections and granite steps leading to Slieve Bearnagh's summit, which may involve some scrambling. While the metadata suggests a duration of just over three hours, be prepared for a longer trek of 4 to 5 hours depending on your pace and conditions. Always be aware that winter weather, including strong winds, snow, and ice, can significantly increase the difficulty and arduousness of this climb, so plan your visit accordingly.

Slieve Bearnagh

Highlight • Viewpoint

Slieve Bearnagh from the Irish “Sliabh Bearna” meaning “Gapped Mountain” gets its name from its two giant rocky tors and the col lying between them. It is the 4th highest in the range and another 700m+ peak carrying the Mourne Wall with saddles at Pollaphuca to the West and Hares Gap to the East.

It is most accessible starting from the Cecil Newman Car Park and following the Trassey Track up and over Hares Gap, turning right and climbing the steps to meet the Mourne Wall which you follow to both summits. The final climb is steep requiring some hands and knees type scrambling. If doing a circular route descending from the North Tor (680m / J315282) to Pollaphuca is also extremely steep so care is required.
