Gljufurarfoss is among the most renowned waterfalls of Iceland only few km. from Seljalandsfoss.
The waterfall Gljufrabui tumbles down from the Gljufurá River. Its source is just north of Trollagil (Troll Gorge) Canyon in the heath Hamragardaheidi. It is a spring-fed river and less voluminous than its neighbour Seljalandsá River.
There are several little waterfalls to be found in the river in the area.
