The Peak District is an upland area in England, at the southern end of the Pennines. Mostly in Derbyshire, it extends into Cheshire, Greater Manchester, Staffordshire, West Yorkshire and South Yorkshire. It is subdivided into the Dark Peak, moorland dominated by gritstone, and the White Peak, a limestone area with valleys and gorges. The Dark Peak forms an arc on the north, east and west of the district, and the White Peak covers central and southern areas. The highest point is Kinder Scout. Most of the area is within the Peak District National Park, a protected landscape designated in 1951.

The Pennines, also known as the Pennine Chain or Pennine Hills, are a range of uplands mainly located in Northern England. Commonly described as the "backbone of England" because of its length and position, the range runs from Derbyshire and Staffordshire in the North Midlands to Northumberland in North East England, near the Anglo-Scottish border. The range starts near the valley of the River Trent to the south and extends northwards across the Peak District, South Pennines, Yorkshire Dales, and North Pennines, ending at the Tyne Gap. Beyond the gap are the Border Moors and Cheviot Hills, which are included in some definitions of the range.
