Vettisfossen is one of Norway´s tallest waterfalls, and the 284 th tallest in the world. It is located in the Jotunheimen mountain range inside the Utladalen Landscape Protection Area in Årdal. The waterfall has a single drop of 275 metres. This is the highest fall which is not regulated through a hydroelectric power station (Måbødalsfossen being the highest).

The waterfall can be accessed by nice walking tour of about one hour from Øvre Årdal up the Utladalen valley. The name of the waterfall comes from the Vetti farm, which is located near the base of the waterfall. The mountain farm Vettismorki is also located nearby, just above the falls.
