Hamish Brown: One with constipated conifer conundrums. Viable parking at forest track off A83 (NR942923). Under pylons turn right and follow this lesser track to its end. Continue on a path which, after about 50 metres, makes an S bend down to a log bridge. Shortly after, an old fence/wall line in a break gives a clear way up; steep with unfriendly bracken in summer.
