The Peak District is an upland area in central and northern England, lying mainly in northern Derbyshire, but also covering parts of Cheshire, Greater Manchester, Staffordshire, and South and West Yorkshire.
Most of the area falls within the Peak District National Park, whose designation in 1951 made it the earliest national park in the British Isles. An area of great diversity, it is conventionally split into the northern Dark Peak, where most of the moorland is found and whose geology is gritstone, and the southern White Peak, where most of the population lives and where the geology is mainly limestone-based. Proximity to the major conurbations of the Midlands, Yorkshire and Lancashire, coupled with easy access by road and rail, make it one of the most visited national parks in the UK.
