The Pennines are a chain of low mountains, which are often called the 'backbone of England', stretching 300 km from Ashbourne in Derbyshire almost to the Scottish border. Much of the land is over 250 m in altitude, with the highest peak, Cross Fell (893 m), being the highest peak in England outside of the Lake District National Park.
