Not yet (actually I didn't know it was there, even though i'ts within walking distance of home). Is it in the nature reserve part do you know, as I let my membership of the local natural history society, which would have allowed me access to the reserve, lapse several years ago.
Also, is it likely to be as good as this one which I saw on the Dolomite trip this year? (Still working my way thorugh the photos from that trip so I have posted any others yet).
