In reply to Joel Perkin:
From Wrynose bottoms scramble to the summit of Little Stand (grade 2), then loads of good nav between there and Pike O' Blisco or head towards Crinkle Crags which is also good nav terrain.
Harter Fell (Duddon) from Birks bridge. Good scrambling on outcrops all the way to the summit, so can mix scrambling with nav. Then head over to Green & crook crags for more nav and scrambling.
Ill crag ridge (Scafells) nav through the Great Moss on the way, really long scramble up the ridge which lands you on the summit, then nav back over the Scafells
