Hen Mountain is one of the less challenging climbs of the Mourne Mountain range, not to worry though, as it still provides the stunning panoramic views that the Mournes are so good at showcasing. There are a few rocky outcrops up here which can be discovered and explored, just do watch your footing as you move about.

The ascent to Slieve Muck from the main road is quite a steep and punchy one. It's a great one to do if you want elevation, and quickly. From the top, you can marvel at the rugged beauty of the Mourne landscape, and, on a clear day, you might even catch a glimpse of the Irish Sea.

Slieve Bearnagh from the Irish “Sliabh Bearna” meaning “Gapped Mountain” gets its name from its two giant rocky tors and the col lying between them. It is the 4th highest in the range and another 700m+ peak carrying the Mourne Wall with saddles at Pollaphuca to the West and Hares Gap to the East. It is most accessible starting from the Cecil Newman Car Park and following the Trassey Track up and over Hares Gap, turning right and climbing the steps to meet the Mourne Wall which you follow to both summits. The final climb is steep requiring some hands and knees type scrambling. If doing a circular route descending from the North Tor (680m / J315282) to Pollaphuca is also extremely steep so care is required.
