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. You can climb it on its own or link it with nearby peaks such as Slieve Donard, making for a truly memorable day in the heart of the Mournes.

Slieve Commedagh is the second-highest mountain in NI at 767m. With spectacular views across Newcastle and over the rest of the Northern Mournes, it is well worth the climb. To reach the peak, head slightly north-east from this point and travel a few hundreds metres.

The Mourne Wall is a significant man-made monument that traverses the principal summits of the Mourne Mountains.

However, for hiking and clearer views, late spring to early autumn (May to September) generally provides more favorable weather conditions. Winter visits can be dramatic but require appropriate gear due to potentially harsh mountain weather.
