The Dark Peak, the more northern area of the Peak District, has high rugged peat moorlands, such as Kinder and Bleaklow, and gritstone escarpments, eg Stanage Edge. The White Peak, the more southern area, has a rolling limestone plateau with many narrow craggy dales, some with a river, eg the dales of the Dove and the Wye. The two landscapes are strongly contrasting. So in choosing somewhere to stay, especially if you want to have some days without driving, it rather depends on which sort of walking you prefer.
