Access: Easy once you've navigated the maze of lanes in this area &/or the roundabouts coming out of Ploufragan. Right next to the road & there is room to stop.

Beautiful! We found it as much by luck as judgement as a result of our only map being a road atlas. It's probably simple to reach from Ploufragan directly with a decent map, but we went spectacularly 'round the houses' (and industrial estates, shopping outlets, motorways, villages, suburbs....)
Coming straight from Ploufragan, you'd also pass Le Menhir du Sabot on a roundabout (not thrilling), another possible menhir (small) by the roundabout just before this site.
I found La Couëte & Grand Argantel particularly reminiscent of some of the hunebedden in the Netherlands.
