Kæfufoss is a cool little waterfall tucked away in Iceland's Skógá River. It's the ninth waterfall you'll stumble upon if you hike upstream from the popular Skógafoss. Dropping 14m over a broad shelf, Kæfufoss forms a V-shape as it cascades down, making for a neat sight along the Laugavegur trail. While not as grand as its neighboring falls, Kæfufoss adds a nice touch to your waterfall-hopping adventure in the area.
