Boncyn Arian

With all the big complex cairns around it is easy to overlook this shapely barrow, but it is easily the most accessible and tallest of the llyns barrows, some are hidden in the forest, some are on the far shore and one even in the lake on an island, but this one is just a few yards from the big ring cairn with wooden posts in it and from the road.

It only just survived as well, when they flooded the valley to make the reservoir, Boncyn Arian was right at the edge of the water, if the wave action continues to wear away at the shore, further undercutting the banks it is only a matter of time before it will need some rescue, it’s safe for now though.
Situated at the head of the Llyn, it seems to command the whole area, most of the sites here are on the hills surrounding the water, except this barrow and the island barrow and a couple on the far shore.
