These waterfalls just east of Mt. Burfell look more like rapids when River Thjorsa swells, but after the construction of the hydroelectric power station Burfell in 1970, the riverbed is almost empty. Between these two waterfalls the third and a nameless one decorates the landscape.

The Thjofafoss (The Waterfall of the Thieves) was named after thieves, who were punished for their crimes by drowning. The Trollkonuhlaup (The Giantess Waterfall) was named after the giantess, who lived in her cave in Mt. Burfell and wanted to be able to get to the other side of the river without getting wet. She threw some boulders into the river as stepping-stones. Her sister lived in a cave in Mt. Bjolfell near Mt. Hekla, and they visited each other every now and then.

A short distance to the east is an oasis by voluminous cold springs, the source of the good salmon river Ytri-Ranga. It only takes a short detour to drive to these waterfalls from the main road.
