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.
