Slieve Binnian is absolute magic. Standing as the third-highest peak in Northern Ireland (747 meters), it easily claims the title for the most dramatic silhouette in the Mournes, thanks to the massive, weathered granite towers—called tors—that guard its summit. https://www.expresstollpass.com

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.
