The Isles of the Blest (or the Fortunate Isles) are a group of three paradise islands in the center of Elysium. It is reserved for those who, upon entering the Underworld, are judged and return to Elysium three times in a row after being reborn.
They are thought to be the equivalent of islands on the western edge of the Earth, with continuous sunlight. Very few people make it to the Isles, as many prefer eternal residence in the pleasant Elysium to risking rebirth and ending up in Asphodel or the Fields of Punishment at the end of another life.
While in the Underworld, Percy noted that the Isles of the Blest was separated from the rest of Elysium by a glittering blue lake, and seemed like a vacation resort in the Bahamas, and he immediately knew that it was where he wanted to go when he died. Annabeth also acknowledged the incredible appeal of the Isles of the Blest, stating it as the place for heroes.
According to Percy's observations, very few people manage to achieve the feat of being a resident of the Isles of the Blest. Luke was supposedly going to choose to be reborn, in order to get to the Isles of the Blest, but it remained uncertain as to whether he really choose rebirth over eternal residence in Elysium.
