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, forests and mountains (or fells) and its associations with the early 19th century writings of William Wordsworth and the other Lake Poets, Beatrix Potter and John Ruskin. A National Park was established in 1951 and, following a minor extension in 2016, now covers an area of approximately 2,362 square kilometres.[2] It was designated as a UNESCO World Heritage Site in 2017.[3]
