Gaukshöfði is a cliff which you are passing on your way into Þjórsádalur valley.

On top of it there is a view point with a great view on mount Hekla and over a big part of Þjórsádalur valley. In June the whole valley appears purple due to the lupines growing on the riverbanks.

Also this place is connected to the Saga about Gaukur. He has been killed by his foster-brother Ásgrímur on this hill.
