Babia Góra National Park (Polish: Babiogórski Park Narodowy) is one of 23 national parks in Poland. It is located in the southern part of the country, in Lesser Poland Voivodeship,on the border with Slovakia. The park's headquarters are in Zawoja. A Nature Reserve covering roughly the same area as the modern-day national park was established in 1933, and the national park itself was officially established on October 30, 1954. Since 1976, UNESCO has designated it as a biosphere reserve. The park covers an area of 33.92 square kilometres (13.10 sq mi), approximately 85% of which is forested. It includes the northern and part of the southern side of the Babia Góra massif. The massif's main peak (known as Diablak), is the highest point of the Orava Beskids mountain range at 1,725 metres (5,659 ft). The Slovak side of the massif is primarily part of the Horná Orava Protected Landscape Area.
