Sigöldufoss, also known as Hrauneyjafoss, used to be a powerful waterfall in Iceland's Tungná River, but it's been tamed by a nearby hydroelectric plant. Now, it flows more gently, but still offers a picturesque spot to visit. Don't forget to check out the Valley of Tears – Sigöldugljufur nearby! You'll likely come across Sigöldufoss if you're cruising along the F208 route to Landmannalaugar.
