The Peak District National Park includes the Dark Peak and the White Peak, named after their distinctive colours from the gritstone and limestone that make them, and is the oldest national park (created in 1951).
Despite the name, there are few mountains – the tallest, Kinder Scout, is just 636m (2087 ft). However, there are some amazingly scenic hills to climb, while the high moorlands create unique wildlife habitats.
The sedimentary rocks that make up most of the area are soft and easily worn away by water, which has led to some stunning caving opportunities, the most famous of which is probably the Blue John Cavern.
