Peak District 2012 A4 Calendar. This stunning 2012 Calendar features the Peak District, an upland area in central northern England. The Peak District National Park is an area of great geological diversity; split into the northern Dark Peak, where most of the moor land is found and the southern White Peak, where most of the population lives. The Peak District National Park was the first National Park in Britain and due to it's proximity to the major conurbations of the Midlands it is also one of our most visited national parks. This Peak District 2012 Calendar will make a fantastic gift idea for those who love this beautiful and scenic National Park!
