A long, demanding day hike to a rock ledge above a lake. It is spectacular and it is not for everyone.
Trolltunga is a cliff that juts out about 700 m above the lake Ringedalsvatnet, in Ullensvang in Vestland, about 17 km from Odda. Wikipedia says fewer than 800 people hiked to it each year until 2010, rising to about 80,000 in 2016.
Visit Norway's listing says experienced hikers can go on their own from June to September, with guided trips from October to May. Wikipedia says it is open to experienced hikers from mid-June to mid-September depending on snowmelt, with guided snowshoe trips from March. When we last read Visit Norway's page it said the trail was closed until 8 June because of rockfall and landslide risk, so check the current status before you plan.
We could not confirm transport details beyond the location, about 17 km from Odda. Check with the trailhead operators.
