The Peak District is a national park with a split personality. In some places it is an untouched Arcadia of leafy dales, blustery heaths and tumbling streams. In others, the land is crisscrossed by railway lines, its hillsides quarried and rivers dotted with mills. Contrary to popular belief, Peak doesn’t refer to hills but supposedly derives from the Peaklanders, an Anglo-Saxon tribe. These are some of the most beautiful spots in the Peak District to explore.
