The High Peak stretches from the heather-clad moors of Park Hall to the gritstone of Derwent Edge, and from the peat bogs of Bleaklow to the limestone crags of Winnats Pass. The wild Pennine moorlands are of international importance for their populations of breeding birds, including golden plover, merlin and red grouse. Sites of particular interest include Mam Tor, with its spectacular views, landslip and prehistoric settlement; Odin Mine, one of the oldest lead mines in Derbyshire; and the unspoilt valley of Snake Pass. Kinder Scout, where the Mass Trespass of 1932 took place, is the highest point for fifty miles around. The Trust also owns several farms in the beautiful Edale valley. A major woodland restoration project (in partnership with the Forestry Commission) is underway in the recently acquired Alport Valley.
