There's a faint track marked on sheet 62 at the north end of Moylisha hill. To get to it you need to enter the white gate at the edge of the farm buildings and walk up to the fifth gate on your left. The farmer was more than happy to allow me up the track and offered directions.
Over the aforesaid 5th gate, walk through 2 fields in a south-east and upward direction and you will spot the site in the corner of the 2nd field by the pine plantation.
This is one of the best sites I've visited in Wicklow. It's a pity that it's not better looked after. The OPW sign was in bits on the ground. The tomb itself is now overgrown with bracken and gorse. Those negatives aside, the stones here are very well preserved and the layout very easy to see. It's a pity that the roofstones are cast aside and left on the ground. A small bit of restoration here would not go amiss.
