Slieve Donard is significant as Northern Ireland's highest peak, rising to 850 meters (2,790 ft). Its summit features a cairn, a small stone tower that is part of the Mourne Wall, and a Neolithic passage tomb, considered the highest surviving passage tomb in Ireland. On clear days, the summit offers expansive views stretching as far as Belfast, Dublin, the Isle of Man, and even the Scottish coast.

Slieve Meelmore, located in the western Mournes, rises to 680 meters (2,230 ft) and is the seventh-highest peak in the range. Its summit is crossed by the Mourne Wall, and there's an old stonemason's hut nearby, suggesting it was a site for gathering materials for the wall. The peak offers excellent views across the heart of the Mournes, particularly of Slieve Bearnagh's picturesque tors. It can be hiked in conjunction with Slieve Meelbeg for a challenging circuit.
