Slieve Bearnagh, Commedagh & Donard loop — Mourne

This difficult loop in the Mourne Mountains challenges you with 12.0 miles (19.4 km) of hiking and a significant 3637 feet (1108 metres) of elevation gain, taking around 6 hours and 54 minutes to complete. You will navigate steep, rocky mountain paths, including sections that require scrambling, especially on Slieve Bearnagh. The reward for your effort is spectacular 360-degree panoramic views of the High and Western Mournes, the Irish Sea, and Newcastle below, with the distinctive rocky tors of Slieve Bearnagh adding to the dramatic scenery.

To tackle this strenuous route, you need very good fitness and sure-footedness. The varied terrain includes unpaved paths, gravel, and natural ground, with some sections of built steps. Be prepared for sustained steep climbs and descents; parts of the trail, particularly descending Slieve Bearnagh and towards Hare's Gap, are very steep and demand extreme caution. Wet or icy conditions can make the already rugged terrain particularly slippery, so plan your visit for clear weather.

The trail takes you over Slieve Bearnagh, Slieve Commedagh, and Slieve Donard, encompassing three of the four highest peaks in the Mourne Mountains, with Slieve Donard being Northern Ireland's highest. You will encounter the iconic 19-mile (31 km) Mourne Wall, which hikers often follow, and sections of the historic Brandy Pad, a former smugglers' track. The Mourne Mountains are designated an Area of Outstanding Natural Beauty, highlighting the unique geological and ecological significance of this challenging and rewarding hiking destination.
