The water in the river is not solely glacial, much springwater pours into it from the Ódaðahraun lava field, hence there is much trout and salmon in it. Several beautiful waterfalls are found in Skjálfandafljót, i.e. Aldeyjarfoss, Hrafnabjargafoss and Goðafoss. The river is also highly popular for rafting.
