Did You Know?

  • Derived from Irish Gaelic, the name translates as 'hill of the little cave' or 'little hollow,' likely referring to a specific topographical feature or indentation on its boggy slopes.
  • It has a larger neighbor nearby called Cnoc na Deirce Móire (Hill of the Great Cave), which stands slightly higher at 379 metres and shares a similar peat-covered character.
  • Its status as a Marilyn—a hill with at least 150 metres of prominence—means it commands a surprisingly grand perspective for its height, looking across the deep valleys to the higher peaks of the Bluestack range.
  • If you actually manage to find the 'little cave' referenced in the name, it might be the only spot on the hill providing a dry seat during a typical Donegal Atlantic squall.
