The Lake District, also commonly known as The Lakes or (particularly as an adjective) Lakeland, is a mountainous region in North West England. A popular holiday destination, it is famous not only for its lakes, forests, and mountains (or fells), but also for its associations with the early nineteenth-century poetry and writings of William Wordsworth and the other Lake Poets.

Historically shared by the counties of Cumberland, Westmorland and Lancashire, the Lake District now lies entirely within the modern county of Cumbria. 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, Wastwater and Windermere, respectively.
