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 1,447-square-kilometre (559 sq mi) park was originally established in 1963, and it was enlarged in 1973 and 2003.
The landscape varies from dramatic peaks of dark granite and grey mountains with little vegetations, to fertile mountain slopes and marshes. The highest mountain peaks are in the west where the bedrock is primarily dark Børgefjell granite, which gives the landscape its desolate appearance. This is where you will find the highest mountain in the park, Kvigtinden, towering 1,699 metres (5,574 ft) above sea level. The 1,513-metre (4,964 ft) tall Jetnamsklumpen is the tallest mountain in Nord-Trøndelag, and it is also located in the park. Other places, such as in the Rainesfjellet area, you will find rough stone screes without vegetation. Sub-glacial moraines cover much of the landscape. There are many lakes, ponds, and raging rivers.
