Børgefjell National Park (Norwegian:Børgefjell nasjonalpark) is an inaccessible and undeveloped national park in Norway, straddling the border between Nord-Trøndelag and Nordland county, with a border to Sweden. The park is for the most part a reservation, with few trails or other facilities for visitors. Visitors can hike for extended periods without seeing another person. The 1,447-square-kilometre (559 sq mi) park was originally established in 1963, and it was enlarged in 1973 and 2003.
