Børgefjell National Park 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 park was originally established in 1963, and it was enlarged in 1973 and 2003.
