This is a lovely monument, a boulder burial. There are four burials, the biggest boulder being about 1 metre high. The boulders themselves are all snarled and have a lot of character. I believe there was a stone circle on the hill next to this Reardnogy Beg that has since been destroyed.
The burial seems to be lined up towards the spur of the Mahur Slieve where the sun rises on Summer Solstice morning.
Best to just pick a gate at the fields on the road for access. There were a few bullocks in the field the time I went to look at it.
