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.

The hike to the Cloghmór Stone feels like a journey through time. Over 10,000 years ago, the ice brought this massive granite block from Scotland here, and now, weighing an estimated 50 tons, it towers majestically over the landscape. But it's not just the geology that's fascinating - according to legend, it was the giant Finn McCool who threw this enormous stone over Carlingford Lough. To be honest, the legend is a much more exciting explanation, isn't it? Once you've reached the top, you'll not only be greeted by the imposing boulder, but also by a fantastic view of Carlingford Lough and the surrounding hills. It's the perfect place to pause for a moment, take in the vastness and enjoy the peace that this place exudes.

A beautiful secluded clearing in the Oak forest. The message on the bench is pretty apt for any trail runners who have slogged up the hill!
