Bjarnafoss is a tall waterfall tumbling right behind the small farming hamlet of Buðir at the junction of route 54 and 574 on the western end of the Snæfellsnes Peninsula (roughly 20km from Ólafsvík). It has been said that under the waterfall stands the "Lady of the Mountains" (Fjallkonan) though we didn't see it out our trip (mostly because we weren't looking for it). However, if you look closely, you might notice basalt columns near the bottom of its main section.
