Valley of the Living Rock

The Valley of the Living Rock is a major setting in Frozen. It is inhabited by trolls, including Bulda, Cliff, Pabbie and many others.

Its name likely references the trolls' ability to transform into rocks at will.

Role in the film
The Valley is known to the King and Queen of Arendelle. Both of them have heard of mystical trolls and their powers, so they travel to the Valley in order to heal Anna.

The "Fixer Upper" sequence takes place in the Valley. Here, the trolls attempt to wed Kristoff and Anna. It can be assumed that Kristoff has spent a lot of time in the Valley with his adoptive family.
