I had a poke around here a few years back. Parked by the phone box across the road IIRC, but never actually found anything I could recognise as a tomb. The gorse was exceedingly high, and it was extremely muddy underfoot. Not ideal conditions.
I did see a couple of large stones, but couldn't get a decent enough view of them to take any photos or positively identify them as a tomb. What I saw was nothing like the piccies on here though.
Sorry I can't help further.
