The summit plateau is L-shaped, incised in the middle by Rawthey Gill, and measures some from end to end. The rock of the plateau is millstone grit, with sandstone and limestone on the flanks, and the Dent Fault ends on the western slope. The highest point at Tarn Rigg Hill (678 m) is in enclosed ground (now with open access), but the trig point on Knoutberry Haw () is only two metres lower and provides excellent views of the Three Peaks, the Howgill Fells, the Lake District and surrounding countryside as far as Blackpool Tower on a clear day. Better views down Wensleydale and the Eden valley may be obtained from Grisedale Pike (), a slight projection on the eastern flank of Baugh Fell just over a mile from the summit.
