Northumberland National Park is the northernmost national park in England. It covers an area of more than 1,050 square kilometres between the Scottish border in the north to just south of Hadrian's Wall. The park lies entirely within Northumberland, covering about a quarter of the county. Of the thirteen National Parks in England and Wales, Northumberland is the most remote from large urban areas, the least populated, and the least visited. The park covers several distinct areas.
