Had a long and challenging day out on Western Gully - 300m, Ysgolion Duon (The Black Ladders). The guide book suggests a grade of severe and 3 stars. Well I think I'll reserve judgement until next winter as I suspect that this route is a lot better in winter conditions when everything is frozen and covered in snow. All I can say is that we had an adventure and that I won't do it again unless there's a drought. There was a lot of thrashing and steep vegetation for a little bit of good climbing so we weren't impresses with the 3 star rating or the grade.
