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.

On the summit of Slieve Meelmore stands a small stone shelter, a welcome spot to rest after the steady climb up. From here, the views stretch across the Mournes, with Slieve Bearnagh’s rocky tors dominating the skyline. The shelter gives hikers a place to pause, shielded from the wind, and enjoy the sweeping mountain scenery before continuing along the Mourne Wall.

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 most popular mountain peak in this region is the Summit of Slieve Donard, which is Northern Ireland’s highest peak. Visitors also highly appreciate Slieve Bearnagh, known for its distinctive rocky tors, and the historic The Mourne Wall, which traverses many of the principal summits.
You'll encounter diverse landscapes, from the boggy moorland and rocky outcrops of Truskmore to the unique Alpine and Arctic-Alpine plant populations on Tievebaun. The Mourne Mountains, featured in the guide, offer stunning views of the Irish Sea, distinctive rocky tors on Slieve Bearnagh, and the impressive scale of the Mourne Wall winding through the peaks.
Yes, the region is rich in history and folklore. Sliabh an Iarainn, for instance, is known for its ancient iron mining history and mythological ties to the Tuath Dé Danann. Sheemore, the 'Hill of the Fairies,' is an important archaeological site with prehistoric cairns. In the Mourne Mountains, the Mourne Wall itself is a significant man-made monument, and Slieve Meelmore summit shelter offers insights into the construction of the wall.
From the Summit of Slieve Donard, you can enjoy panoramic views of County Down, and on clear days, even the Isle of Man, Anglesey, and the West Coast of Scotland. Truskmore offers breathtaking 360-degree views of the Dartry Mountains, Glencar Lough, Benbulben, and the Atlantic coastline. Sheemore provides a vast 360-degree panorama across North Leitrim into several surrounding counties.

For cycling, options range from moderate to difficult, such as the 'Carrick Little to Tullymore Forest loop' or 'The Head Road Route'.
