Chrome Hill /ˈkruːm/ is a limestone reef knoll in Derbyshire, England, in the upper Dove valley beside the border with Staffordshire. It is adjacent to Parkhouse Hill, another reef knoll. The walk over Chrome Hill and Parkhouse Hill is known as the Dragon's Back ridge. Chrome Hill was declared open access land under the provisions of the Countryside and Rights of Way Act 2000. However, the only access from the north west remains along a concessionary footpath. Chrome Hill contains good exposures of Gigantoproductus fossils; it is part of a designated Site of Special Scientific Interest which makes it an offence for visitors to remove geological samples.
