What is the name of the valley where the trolls live in Frozen?

The valley where the trolls live in Frozen is called the Valley of the Living Rock.

The valley is the trolls’ home and appears when Kristoff brings Anna there for help after Elsa’s magic freezes her heart. The trolls disguise themselves as ordinary rocks, making the name a literal description of the landscape as well as a whimsical title for their settlement.

Grand Pabbie leads the troll community and examines Anna after she is struck by Elsa’s ice magic. He explains that only an act of true love can thaw her frozen heart. The trolls also sing “Fixer Upper,” trying to push Anna and Kristoff toward a romance while they are gathered in the valley.

Some viewers use informal descriptions such as “Troll Valley,” but that is not the canonical name used in the Frozen setting. The location is also referenced in later Frozen-related stories, including LEGO Frozen Northern Lights. It should not be confused with the North Mountain, where Elsa builds her ice palace, or the Enchanted Forest, which is central to Frozen II.
