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 Binnian also has an impressive hidden feature, the Binnian Tunnel, built beneath the mountain to transport water.
The Mourne Mountains are primarily a granite range, which gives them their distinctive appearance. Many peaks, such as Slieve Binnian, Slieve Bearnagh, and Hen Mountain, are renowned for their dramatic granite tors and outcrops.
