At its lowest point the parish is about 120m above sea level, but the valley sides rise to 370m at the highest points above Rowarth. The watercourses to the north, particularly the Rowarth Brook, drain the southward slopes of Mellor Moor, Cown Edge and Lantern Pike. The Sett and its tributary the Kinder drain much of the plateau of Kinder Scout; the Sett flows through Hayfield before passing through Birch Vale to the Torrs and the River Goyt. The Goyt rises on the moors of Axe Edge, near the River Dane and the Cat and Fiddle Inn between Buxton and Macclesfield. It passes through Whaley Bridge, where it is joined by the Todd Brook and the Black Brook from Chapel-en-le-Frith. The sides of the Goyt valley have been used to carry two railway lines, the Peak Forest Canal and the A6 trunk road from London to Carlisle via Manchester; these all pass through New Mills.
