About Fairy Castle guided day hike in the Dublin Hills

The hike starts on the outskirts of Dublin, where we walk up through the Kilmashogue forest on a well made track , as we ascend we will get a fine view across Dublin to Howth Head and the coast, and on a fine day can see as far as the Mourne Mountains to the north. We continue uphill on the Wicklow Way, a good mountain path, and as we approach Fairy Castle there are far reaching views of the Wicklow mountains to the south.

Fairy Castle is a Bronze Age cairn on the summit of Two Rock mountain, dating from 2000 – 2500BC, it has never been excavated but is known to be a collapsed passage tomb. The original cairn is now topped by a much more recent one and the top of our climb. From here we descend south on a stony path, a little tricky in places, until we reach an entrance to a conifer plantation. We then take a forest track that contours around the hill until we reach the telecommunication masts at Three Rock.

The track continues until we rejoin our upward route and descend to the car park.
