About Slievenalargy [Tullynasoo Mountain]

Rising above the Shimna Valley, this modest foothill offers a quieter perspective on the Mourne Mountains than the high granite peaks. Despite its low elevation, its status as a Marilyn ensures a sense of independence, providing clear, unobstructed views toward the northern faces of Slieve Meelmore and Slieve Meelbeg.

Did You Know?

  • The primary name, Slievenalargy, is derived from the Irish Sliabh na Leargaí, meaning 'mountain of the slopes', while its alternative title, Tullynasoo (Tulaigh na Sú), translates to 'hill of the berries'.
  • Situated northwest of the main Mourne range, the summit provides a sweeping panorama of the high peaks, specifically overlooking the transition from the Trassey track toward the stony silhouettes of Slieve Meelmore and Slieve Meelbeg.
  • Despite standing at just 280 metres, it is classified as a Marilyn because it is separated from the higher mountains by a drop of over 150 metres, giving it far more prominence than its height suggests.
  • If the name Tullynasoo holds true to its translation, the most significant obstacle to reaching the summit in late summer is the temptation to stop and forage.
