It was years ago, but I spoke to the farmer who was out in the yard and asked permission. Finding the right farm house might be a challenge, but you could ask around. He had me walk up along the edge of his field.
Maybe it's a different owner now and perhaps they don't realize what a fine neolithic site they have on their property, or perhaps they just don't care.
