Trolltunga (Troll tongue) is a rock formation situated about 1,100 meters above sea level in the municipality of Odda in Hordaland county, Norway. The unique cliff is jutting horizontally out from the mountain, into the free air about 700 meters (2,300 ft) above the north side of the lake Ringedalsvatnet. The popularity of the hike to Trolltunga and rock formation itself has exploded in recent years. The increased popularity has turned Trolltunga into a national icon and a major tourist attraction for the region. Until 2010, less than 800 people hiked to Trolltunga each year. In 2016 more than 80,000 people hiked the 27 kilometers round-trip from Skjeggedal, making it one of Norway's most popular hikes.
