Trolltunga is a piece of rock that stands horizontally out of the mountain above Skjeggedal in Odda, Norway. To get to Trolltunga (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[1]. There are, however, both stairs and a path that guide visitors the first 950 meters, and from there marked hiking trails lead visitors the rest of the way.

Cabins in the area are 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.
