Kjeåsen is a mountain farm in the municipality of Eidfjord in Norway's Hardanger district, in Hordaland county. The farm lies at an elevation of at the innermost point of the Simadal Fjord. The farm is no longer being worked, and one person lives there during the summer. The site is popular with tourists, especially Swedes. The farm has been referred to as "the world's most inaccessible farm." Kjeåsen can be reached on foot up the steep path from the Sima Hydroelectric Power Station. This was the farm's road until 1974, and the trip takes about 1½ to 2 hours each way. Kjeåsen also has what is known as "the world's most expensive farm road"; it is long, of which approximately consists of a tunnel from the Sima Valley to the farm. The tunnel has a single lane, with driving directions scheduled up on the hour and down every half hour. The road and tunnel to Kjeåsen were built in 1974 in connection with power development in the Sima Valley. The tunnel has now been outfitted with lights. Walking and cycling are not permitted in the tunnel. The name Kjeåsen comes from kje 'kid' and ås 'hill', inflected for definiteness. The farm has been inhabited at least since the 1650s. Until the road up to the farm was built, all transport took place on the steep path from the bottom of the fjord. In the 1930s a cable car was built that could carry food and others material up to the farm. However, the residents of Kjeåsen still had to use the trail as before. The outlying farmstead at Kjeåsen was vacated in 1962, and since 2010 the other farmstead has been inhabited only in the summer. The outlying farmstead was sold in 2016 after several hundred years in the same family. The Swedish author Bror Ekström visited Kjeåsen in the 1950s and wrote a book about the people living there. His work, Folket på Kieåsen, was first published in 1958 and became very popular. In Norway, Halldor O. Opedal published Kjeåsfolket i Hardanger. Soga om eit utkantfolk in 1980. In 2001, Reinhard Kungel made a film for the German broadcaster ARD about the last mountain farmers in Norway. In Kjeåsen, he portrayed the last inhabitant, Bjorg Wiik. The Norwegian broadcasting company NRK aired a program about Kjeåsen in its seriesDer ingen skulle tru at nokon kunne bu in 2002. Sveriges Radio, the Swedish nationalradio broadcaster, has also aired a program about the farm.
