The Yorkshire Dales National Park is a 2,178 km (841 sq mi) 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. More than 95% of the land in the park is privately owned; there are over 1,000 farms in this area.
In 2020, the national park was named an International Dark Sky Reserve. This means that the area has "low levels of light pollution with good conditions for astronomy".
