Not that I have an OS map in front of me but I believe the location is called 'Clairemont Cairn' on the relevant OS map. I think that it is on the route of the annual 'puc fada', long distance hurling for anyone who doesn't know already, nothing to do with goats.
When are you lads thinking of trying it out? Its probably the best part of an hour from my base, so weather and visa's permitting I might get a day out as well.
