Gruggandoo

Tucked away in the western Mournes, this heather-clad peak offers a quieter alternative to the high granite summits. Rising above the Spelga Reservoir, its moderate height belies a rugged character and clear views across the Upper Bann valley. It is an accessible Marilyn, often combined with its neighbour, Slievenaman.

• •The name derives from the Irish 'Grógán Dubh', meaning 'black hillock' or 'black ridge', likely referring to the dark, peaty heather that covers its slopes in contrast to the paler granite scree of the higher Mourne peaks.
• •The summit provides an excellent vantage point for viewing the Spelga Dam and the distinctive, craggy profile of Pigeon Rock Mountain directly to the south.
• •It is frequently climbed as part of a circuit of the 'Western Mournes', a quieter region of the range that avoids the heavy foot traffic of the Slieve Donard and Silent Valley routes.
• •At 382 metres, it successfully qualifies as a Marilyn, proving that in the Mournes, you do not need to be a giant to earn your own distinct status in the logbooks.
