Did You Know?

  • The Irish name Sliabh Collann translates as 'Hill of the Hazel', while its English name, Mount Oriel, references the ancient Kingdom of Oriel (Airgíalla) that once spanned this region.
  • On a clear day, the summit offers a commanding perspective over the Louth plains towards the Cooley Mountains and the more distant, jagged silhouette of the Mourne Mountains in County Down.
  • The hill is often climbed via the forest tracks from the nearby village of Collon, passing through woodland originally developed as part of the local estate in the 18th century.
  • The presence of a substantial telecommunications mast at the summit means you are more likely to find a strong 4G signal than a sense of remote wilderness.
