The Pennines, also known as the Pennine Chain or Pennine Hills, are a range of uplands running between three regions of Northern England: North West England on the west, North East England and Yorkshire and the Humber on the east. Commonly described as the “backbone of England”,[2][3] the range stretches northwards from the Peak District at the southern end, through the South Pennines, Yorkshire Dales and North Pennines to the Tyne Gap, which separates the range from the Border Moors and Cheviot Hills across the Anglo-Scottish border, although some definitions include them.
