Gullfoss Waterfall

The river Hvítá flows to the south but takes a sharp right turn about a kilometre above the waterfall and flows into a wide curved three-step „staircase“. The highest flood measure of the waterfall was 2,000 cubic meters however the average amount of water running down the waterfall is 141 cubic meters in the summer and 80 cubic meters in winter.

Gullfoss means Golden falls and the origin of its name is unknown. Some speculate that it got its name because when the sunlight hits the waterfall it glows like gold or because of the rainbow that forms in the mist. As the story says, you may find gold at the end of the rainbow.

When Traveling to Kjölur/Kjalvegur

It is important to respect nature while driving to Kjölur. The landscape is very delicate and it needs to be shown full respect.  Driving off-road is illegal in Iceland and it can lead to heavy fines.  

It is also important to keep in mind while hiking in Kjölur as well as all mountains to not walk outside of the walking paths and please do not step on the moss. The moss is very vulnerable and takes many years to heal if it is damaged.
