Trolltunga (English: Troll tongue) is a rock formation situated about 1,100 metres (3,600 ft) above sea level in Ullensvang Municipality in Vestland county, Norway. The cliff juts horizontally out from the mountain, about 700 metres (2,300 ft) above the north side of the lake Ringedalsvatnet.
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, fewer than 800 people hiked to Trolltunga each year. In 2016 more than 80,000 people hiked the 27-kilometre (17 mi) round-trip from the village of Skjeggedal, making it one of Norway's most popular hikes.Provided By: https://en.wikipedia.org/wiki/Trolltunga
