Thanks matey! That's more or less what we did. The gate's at more or less SE060630 - just to the east of the lane looking at http://www.streetmap.co.uk/streetmap.dll?Grid2Map?X=406400&Y=463100&title=Appletreewick%20(%20Stone%20Circle)&nolocal=X&bimage=background%3dhttp://www.themodernantiquarian.com/images/streetmap_back.gif&zoom=4&arrow=Y
I've just discovered that my mate Ginger John claims to have found it (though not that I don't trust him...he seemed a bit vague!) so I'm going to drag him out there at the weekend.
Any other help you or anyone else could give would still be welcome as I'm not convinced by the big Ginger one.
If I'm not around next week, you'll know I'm still looking....
love
