Also thinking of doing this one. Some discussion of route off St Sunday Crag here and a GPS plot here but the closest to a list of CPs I can find is the Achille Ratti site description "The first top is Catstye Cam followed by Helvellyn, Dollywaggon, Grisedale Tarn and then St Sunday Crag. The return journey is via Grisedale Beck to Hole in the Wall and back to Glenridding Village Hall". Does anyone have a GR for Hole in the Wall as my OS has it at 360155 - nowhere near where said GPS track appears to go ...
