Greenfield is at the western end of the Chew Valley in the south west edge of the South Pennines and is fringed by the Peak District to the east. The village contains four reservoirs, three of which are linked to one another: Greenfield, Yeoman Hey and Dovestones. The fourth is Chew Reservoir at the head of Chew Valley, which is the highest man-made reservoir in England. There is a yachting club on Dovestone Reservoir, the largest of these, and a set of walking paths round the first three. A steep walking path also connects Dovestones to Chew Reservoir. Much of the area covered by the reservoirs lies within the boundary of the Peak District National Park.
