The five superb valleys that make up Derbyshire Dales National Nature Reserve lie in the centre of the Peak District National Park
The Dales and Peak District National Park together represent some of the best examples of limestone geology, landscape and wildlife in the area and indeed in the whole of England. The five valleys that make up Derbyshire Dales National Nature Reserve cover a total of 385 hectares. 87% of this is classed as a Site of Special Scientific Interest (SSSI) for either its wildlife or its geology, in addition to which just over three-quarters is a Special Area for Conservation (SAC). Although each of the valleys has its own unique characteristics, all are notable for their limestone scenery, their diverse flora and the wide range of butterflies and other insects this supports.
