May 25, 2026, Slieve Binnian Summit

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

The well-maintained trails take you through impressive scenery, surrounded by the striking peaks of the Mournes. The view of the Mourne Wall, which stretches for 35 kilometers and connects 15 peaks, is particularly impressive. However, some sections can become slippery in wet weather, so caution is advised. A highlight is a visit to Ben Crom Reservoir, which can be reached via an extension of the route. Note that there is a fee to enter the park.
