Millers Dale is a valley on the River Wye in Derbyshire. It is a popular beauty spot in the Peak District of England, much of the area being preserved as a Site of Special Scientific Interest. Nearby is Ravenstor and Cheedale, both popular with rock-climbers. Just to the north of the Dale lies the village of Wormhill and the lesser known valleys of Peter Dale and Monk's Dale, the latter being listed as a Site of Special Scientific Interest and a nature reserve. Large sections of the trackbed now form part of the Monsal Trail, a cycle and walking trail.
