Harrold Thomson: Don't try to access this via the bridge over the River Roy shown on the OS map at NN296846 - it no longer exists (although it's been a substantial bridge in its day). We walked down from the 'Stone' shown on the OS map, on a fairly well-defined path, to be faced with a raging torrent and no bridge. We settled for the western Leana Mhor instead. (AD: I remember that bridge required a nervous crawl back in 1993.)
