What Fire Nation island is the setting of the episode The Beach?

The Fire Nation island where “The Beach” takes place is Ember Island.

Ember Island is a resort destination associated with the Fire Nation’s wealthy and powerful families. In the episode, Zuko, Azula, Mai, and Ty Lee travel there and stay at a beach house connected to the royal family. The sunny vacation setting contrasts sharply with the characters’ personal instability and the war surrounding them.

The episode uses Ember Island as a pressure cooker for the four young antagonists. A beach volleyball game, a party hosted by Chan, and arguments over romance expose their insecurities. Zuko’s jealousy, Mai’s emotional reserve, Ty Lee’s fear of being indistinguishable from her sisters, and Azula’s anxiety about her mother all surface during the visit.

Ember Island is not Kyoshi Island, which is associated with the Kyoshi Warriors and the Earth Kingdom. The episode’s island setting is also distinct from Crescent Island and other locations that appear elsewhere in the franchise. The island’s name is a direct clue to its volcanic Fire Nation identity.
