- "You are a courageous one. Not many have dared explore Isla Sirena, and fewer still have been invited to meet us in our lair. You intrigue us."
- ―The three "Blue Tails" to Jack Sparrow[src]
Isla Sirena was a mysterious island that resided in Davy Jones' Locker, but could also appear in the real world.
Isla Sirena was surrounded by mist which helped disguise its presence as nothing more than sea mist to sailors. Water surrounding the island were inhabited by at least one sea beast. The island was primarily home to the Sirens, who used the mermaids as their agents to lure sailors to their doom. The island moved between Davy Jones' Locker and wherever in the surface world the Sirens wish it to be located.
A young Jack Sparrow visited the island twice during his adventures in his teenage years. Jack's first visit was a result of his crew of the Barnacle falling captive to the song of the mermaids. Though the song immediately took control of Jack's crewmates, it somehow had no effect on Jack himself. Following Arabella Smith's sudden attempt to reunite with her mother, whom she thought was dead, Jack was attacked by a group of mermaids, and was hardly able to return to his ship.
But when an ivory white hand beacons him to return to the sea, he was unable to resist, and found himself devoured by a whirlpool, which led him to Isla Sirena. Jack would then meet with the Siren's mermaid agents: Morveren, Aquala and Aquila.
