The waterfall drops from the cliffs above it, fed by Lake Þórutjörn. It belongs on the Klaustur-to-Skaftafell part of a drive, rather than the road between Vík and Klaustur. The regional guide describes a route toward Þórutjörn, but that is separate from a brief view of the waterfall. Follow local access signs before taking it.
