A unique waterfall in the river Seljalandsá, about 17 km west of Skógar. It is 60 meters high with a foot path behind it at the bottom of the cliff, but with a thin cascade. It is the only known waterfall of its kind, where it is possible to walk behind. The waterfall is very picturesque and therefore its photo can be found in many books and calendars. Access to the waterfall is from the farm of Seljaland along the Ring Road, Iceland's main highway. A little further to the west there are several other falls, among them the interesting Gljúfrabúi which is partially masked by its own canyon.
