Avdalen is a small, 1-kilometre (0.62 mi) long side valley located off of the main Utladalen valley in Årdal Municipality in Vestland county, Norway.

It is located within the Utladalen Landscape Protection Area, which was established along with the adjacent Jotunheim National Park in 1980 and covers about 300 square kilometres (120 sq mi).

[1] The Årdal mountain touring club maintains a staffed lodge at the former Avdal farm (Avdalen gård).

It can be reached by a 2 kilometres (1.2 mi) car ride from the village of Øvre Årdal to Hjelle, followed by a 45-minute hike.

The last part of the hike is very steep and illustrates the challenge of daily life for the former residents.
