Derbyshire is a county in the East Midlands of England. A substantial portion of the Peak District National Park lies within Derbyshire, containing the southern extremity of the Pennine range of hills which extend into the north of the county.
The county contains part of the National Forest, and borders on Greater Manchester to the northwest.
Most of Derbyshire consists of rolling hills and uplands, with the southern Pennines extending from the north of Derby throughout the Peak District and into the north of the county, reaching a high point at Kinder Scout. The south and east of the county are generally lower around the valley of the River Trent, the Coal Measures, and the areas of clay and sandstones between the Peak District and the south west of the county.
