This tomb is close to Murroe in Co. Limerick and to Glenstall Abbey. Follow the OS Map past about 2 houses on the left. The map shows a track into the woods. Best to follow this because one track where the break that looks the obvious way on OS map takes you alongside a house and they keep horses.
Follow the track to the end and then it naturally tails left following the tree-line (Not shown on the map). Head North west for about 300m and there is a gap on the right into a field. Once in the field you should be able to see the tomb to the north west in the corner of the field.
When i visited the tomb was water-logged. However it is in good condition, about 5m long and I think that all of the stones are there. To the North West is Sliabh Eibhlinne and the North is Sliabh Kimalta. However both are obscured by the trees.
