The Lake District, also known as The Lakes or Lakeland, is a mountainous region in North West England. A popular holiday destination, it is famous for its lakes and mountains and it's associations with the early 19th century poetry and writings of William Wordsworth in village Grasmere and the Lake Poets. All the land in England higher than three thousand feet above sea level lies within the National Park, including Scafell Pike, the highest mountain in England. It also contains the deepest and longest lakes in England. The Lake District is approximately 34 miles (55 km) across and lies entirely in county Cumbria. The central and most visited, part of the area is contained in the Lake District National Park which was designated as a National Park in 1951.
