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.
