In reply to Stephen Reid - Needle Sports:
I don't have the guidebook to hand so don't know which way it gives as the approach but the Duddon Valley fell race passes under Gaitkins on its way to Wrynose and is steady going (there's a broad terrace passing under the crags) so I'd walk in from that way, i.e. the race route in reverse. Start as if you are walking up to Black Crag and then after about 400 metres head west to pass to the north of Rough Crags and contour round to the crag. About 1.6Km with 200 metres of ascent.
