Husedalen is the valley behind Kinsarvik where the Kinso river drops 840 metres from Hardangervidda to the fjord. Along the way it forms four waterfalls: Tveitafossen, Nyastølsfossen, Nykkjesøyfossen, and Søtefossen. The hike to see all four takes 5 to 6 hours return.
The first waterfall is easy to reach on a gravel road. Most visitors stop there. Beyond that the trail gets steeper and rougher, climbing alongside old hydropower pipelines. The path can be slippery when wet. Proper hiking boots are essential. The crowd thins out with each waterfall. By the fourth, Søtefossen, you'll likely have it to yourself.
Three of the four waterfalls are inside Hardangervidda National Park. The trail continues to Stavali, a DNT cabin on the plateau, if you want to make it a longer expedition. But for a day hike, turning back at Søtefossen is enough.
Start from the car park at Vivippo bridge, a short drive from Kinsarvik centre. You can also walk from the village if you want to add distance.
