Mullaghanish, or Mullach an Ois, is a 649-metre-high Irish Hewitt, not far from the hamlet of Ballyvourney in County Cork. It is home to the highest television transmitter mast in Ireland (225 m). As such, the trail to the summit is by way of a mast service road through the woods. You will have around 400 metres of height gain to do on the winding service road to the top, but you will have some lovely views for very little effort.
