It stretches north from the village of Øvre Årdal into the neighboring Luster Municipality.

The main valley, when measuring from Øvre Årdal is 25 kilometres (16 mi) long and is surrounded by dozens of mountain peaks that are all more than 2,000 metres (6,600 ft) in height.

From Øvre Årdal, a comfortable walking road has been constructed, funded by voluntary contributions.

The road passes through the Vetti farm area and crosses the Utla river on four spectacular bridges.

It includes both the valley and areas that extend both westward and northward to Jotunheim National Park, and eastward to lake Tyin.
