Pathways to the Past organized a walk to this site on Sunday 25th May 2014. It is indeed an impressive place. Just to prove it was easilly possible I climbed upwards through the creep passage. I am about 5ft 11 and 12 stoneish and did it easilly mostly stooped with my hands on the ground just having to actually crawl for a short way.
I have done the same at other fogous. They are much easier than it looks and anyone of normal size could do it quite easilly.
the creep passages were originally the only way in to these enigmatic sites. I am posting a photo of the creep passage. Bizzarely a face that is like mine appears on the entrance wall!
It was very wet which may explain the distortions!
Something is not right. This message is just to keep things from messing up down the road
