Ascents can be made from Patterdale village, either direct up the nose of the ridge, or by curving round to the west and following the Glenamara Park wall. Trough Head can also be reached from either Deepdale or Hag Beck, providing an approach from 'behind' the summit. Arnison Crag is often climbed as the first part of the ascent of St Sunday Crag. From here the walker can either circuit Deepdale via Fairfield, Hart Crag and Hartsop above How or swing north around Grisedale, taking in Dollywaggon Pike, Nethermost Pike and Helvellyn.
