Hokani Falls is a location.
As a child, Kenai formed a friendship with a girl from another tribe named Nita. The two often played together. One day, Nita fell through a frozen lake, and Kenai dove in after her, saving her life. While helping her recover at Hokani Falls, Kenai gave Nita an amulet. Unbeknownst to the two, the amulet bonded them in the eyes of the Great Spirits.
Many years later, after Kenai was transformed into a bear, he and Nita set out for Hokani Falls in order to burn the amulet and thus sever their bond. The trio eventually reached Hokani Falls, where Nita burned the amulet. Afterward, Nita realised that due to finishing her mission, her ability to talk to animals had stopped; thus, she could no longer understand what Kenai and Koda were saying. Nita sadly returned to her tribe to resume her wedding.
