Etna (river)
Etna is a river in the Valdres region of Innlandet county, Norway. The long river flows through Øystre Slidre Municipality, Nord-Aurdal Municipality, Etnedal Municipality, and Nordre Land Municipality before joining the river Dokka at the village of Dokka in Nordre Land Municipality. Soon after the confluence of those two rivers, they join the Randsfjorden.
The river begins near the mountains Skaget and Langsua inside the Langsua National Park. It then flows in a southerly direction. Much of the river runs through the Etnedalen valley. The river runs through the village of Bruflat and then shortly after this, it begins heading in a more easterly direction. The river was formally protected from hydropower development by the government in 1993.
