I met an old man on the way up to this, we talked about tipperary hurling and he gave me directions. Seems this is hill-walking country and quite a few people go up to this wedge tomb that is associated with the story of Diarmuid and Grainne. The tomb seems to have been visited recently as I could follow a path through the long grass. The tomb itself is overgrown, id say it would be worth photographing in winter when some of the overgrown had receded. It must be about 3-4m long with the main stones being at least 1.5 high.
The conical peak of Temple Hill is what I saw from the tomb but it doesnt seem to be pointed towards it but to the smaller hill in the distance. Ill have to find out its name.
