Visited in May 2009, a very long time coming! Been trying to get to here for years, funny being in Wales, but sometimes you never look or visit some things nearer to you.
I found the site relatively easy to find considering I visited alone with no map reader. Parking is good for a few cars, and nice path with good gates down to the Monument itself. Seeing this in books over the years I had an image it was much bigger than it was, but the only gripe I have is that its fenced in, crap for us photographers not wanting posts and fence wire in the frame!
Do take the time to visit, I will be returning soon.
