It stands at the western end of the Grisedale Pike- Hopegill Head ridge overlooking Crummock Water. The North Western Fells occupy the area between the rivers Derwent and Cocker, a broadly oval swathe of hilly country, elongated on a north-south axis. Two roads cross from east to west, dividing the fells into three convenient groups. The central sector, rising between Whinlatter Pass and Newlands Pass, includes Whiteside.
