Slievenaglogh

About Slievenaglogh

Resting above the western shore of the Silent Valley Reservoir, this granite-strewn Marilyn offers a rugged perspective of the High Mournes. Its name translates as 'mountain of the stones', a reference to the weathered boulders and rocky outcrops that define its slopes as they rise steeply above the coastal town of Kilkeel.

Did You Know?

• •Slievenaglogh comes from the Irish Sliabh na gCloch, translating as 'mountain of the stones.' This refers to the abundance of granite boulders and weathered tors that litter the summit and upper slopes.
• •The summit is bisected by the Mourne Wall, a monumental 22-mile dry-stone boundary built between 1904 and 1922. This specific stretch was designed to prevent livestock from contaminating the water supply of the Silent Valley Reservoir.
• •From the summit, walkers gain a clear, dramatic view of the Silent Valley and Ben Crom reservoirs, framed by the jagged tors of Slieve Binnian and Slieve Lamagan to the east.
• •It is a central feature of the Western Mournes ridge walk, a route that typically connects Slievenaglogh with the neighbouring peaks of Slieve Muck to the north and Carn Mountain to the south.
• •At 445 metres, it is high enough to offer a proper mountain experience while remaining low enough that you can usually be back in Kilkeel for lunch before the afternoon mist has finished rolling in.
