To get to Trolltunga, which is Norwegian for "Troll's tongue", visitors needs to go to Odda, then to Skjeggedal via Tyssedal. Previously a trolley car transported visitors the first 950 meters above sea level during the summer. There are however both stairs and a path that will take you the first 950 meters, and from there marked hiking trails will take you the rest of the way.
There are cabins in the area owned by the Norwegian Trekking Association where it is possible to spend the night. The area opens up to the rest of Hardangervidda, and can be a starting point for a longer hike to for example Hårteigen.
