Dölufoss or Dalárfoss is a waterfall in the river Dalá (also known as Dala). Dalá is a smallish spring-fed river, which swells only during the spring thaw. It flows through a rather large and picturesque gorge, Dölugil.
Dölufoss, the waterfall at the front of the gorge, is a beautiful cascade which tumbles down 30 metres in two stages: the upper falls are separated into two halves, below which the river flows together and forms a single narrow lower cascade.
The river flows on to join the Kverna river downstream.
