Did You Know?

  • The name Fairy Castle refers to the substantial Bronze Age passage tomb crowning the summit, though its alternative Irish name, Sliabh Lecca, translates as the 'mountain of the flat stones.'
  • On a clear day, the summit provides a sweeping panorama that stretches from the distinctive volcanic profile of the Great Sugar Loaf in the south across to the Mourne Mountains in Northern Ireland.
  • It is most commonly reached via the forest tracks of Ticknock, following a well-trodden section of the Dublin Mountains Way that links the peak to its lower neighbour, Three Rock Mountain.
  • The summit offers one of the best perspectives of Dublin Bay, allowing walkers to clearly identify the Poolbeg chimneys, Howth Head, and the Bull Island sandspit.
  • Despite the name Two Rock, the summit plateau actually features several large granite tors, making it a rare example of a mountain that somewhat undersells its geological assets.
