The Yorkshire Dales National Park is a 2,178 km2 national park in England which covers most of the Yorkshire Dales, the Howgill Fells, and the Orton Fells. The Nidderdale area of the Yorkshire Dales is not within the national park, and has instead been designated a national landscape. Most of the park is within North Yorkshire, with a sizeable area in Cumbria and a small part in Lancashire. The park was designated in 1954, and extended in 2016.
