Céide Fields

Beneath the wild bog lands of North Mayo lies Céide Fields, the most extensive stone age monument in the world which is soon to be classed as a World Heritage Site; with field systems, dwelling areas and megalithic tombs of 5,000 years ago.

In addition, the wild flora of the bog is of international importance and is bounded by some of the most spectacular rock formations and cliffs in Ireland. (75 km from Mulranny – 1 ½ hours drive)
