At the western edge of the Hardangervidda plateau, you’ll find Trolltunga – the most spectacular rock formation in Norway. Trolltunga is a rock jutting into space 700 metres above Ringedalsvatnet lake! The hike through high-mountain terrain up to Trolltunga is long and demanding, but you are rewarded with magnificent views. The trail to Trolltunga, situated at 1180 metres, is signposted. From the main trailhead at P2 in Skjeggedal, the round-trip hike is 28 km with an ascent of almost 800 metres. The estimated hiking time is 8–12 hours. There is an additional trailhead at P3 Mågelitopp. The round-trip hike from P3 Mågelitopp is 20 km with an ascent of about 320 metres. The estimated hiking time is 7–10 hours.
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.[2]

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[3] the 27-kilometre (17 mi) round-trip from the village of Skjeggedal, making it one of Norway's most popular hikes.[4]

This is a very challenging hike, at least 10 hours on rough terrain. There are no shelters on the hike route and no places to buy supplies. However, there is a plan to build a lodge roughly halfway where hikers can rest.
Near the parking area at Skjeggedal there is a funicular called Mågelibanen (it is not in operation). The trail to Trolltunga begins here, on the left side of the funicular. It is marked with red Ts painted in the terrain, and signs along the route that marks the distance left to Trolltunga and to the starting point at Skjeggedal.

For the first 1.5 kilometres (0.93 mi), up to the Måglitopp, the trail rises about 450 metres (1,480 ft). From here the track surfaces slightly out before it gets steep again, rising another 330 metres (1,080 ft) up from Gryteskaret to Trombåskåret. This section is the steepest part on this hike. But in recent years this section have been improved by Nepalese sherpas, making it easier to traverse.

After this 4-kilometre (2.5 mi) steep climb from the parking area, the next section slopes down towards Store Floren. The trail continues over Hesteflåene and the dried out river Endåno, before it gets steeper up to Endanuten and crosses the dried river to Tyssestrengene. From here the trail goes on past glacial potholes, then continues past Tysshøl, and finally approaches Trolltunga, about 13.5 kilometres (8.4 mi) from the starting point at Skjeggedal.

Trolltunga is accessible for experienced hikers and guided groups from mid-June to mid-September, depending on when the snow melts in the Spring. The season for guided trips with snowshoes or skis starts in March.

Trolltunga is located in a region with a mild and humid coastal climate. During summer and autumn the weather conditions often change quickly – from blue sky to wind, rain and dense fog. Check the weather forecast and ask locals about what kind of weather to expect before you go hiking.

Due to the long distance, hikers to Trolltunga need to start before 10:00 AM in the summer season[2] to get home before it gets dark and cold. In September it is recommended to start 8:00 AM at latest, since it gets darker earlier in the evening.
