This site is fairly straightforward to get to, although not necessarily easy. There is plenty of parking space at White Wells carpark - walk to the old pump house and then head due south uphill keeping the white building of the old bathhouse to your left and head towards the waterfall. Once you get there, there is a very steep climb up beside the small falls (there may well be easier routes round the side) that leads to the outcrop of land the forms the north end of Willy Hall's Wood which is a wonderful place with an air of 'sacred grove' about it. Continue south through the trees and just before they end you will find a large tilted stone with carvings across its southern face.
These carvings consist of about 17 cups, some of which have rings and some with interconnecting grooves. Due to the position of the sun I was unable to get a decent photograph of the carvings on this visit - maybe next time.
Just beyond the carved rock is another boulder that has three large saucer shaped indentations - I thought they may have been man-made but found out later from a knowledgeable local that he believed they were natural.

Update 2009:
A recent visit to the site in brighter light allowed me to get pictures which were a little better but the eroded nature of the carvings still make identifying them difficult. It's good to see that most of the traces of red paint that was daubed on the stone in 2003 have disappeared although some new graffiti is evident on the right hand side of the top picture.
