How has Golding made the island appear isolated in Lord of the flies?

Answer 1

The remote tropical island serves the twin purposes of isolating the boys away from adults and it also provides them with easily accesible food.

Answer 2

Golding establishes the island's isolation by describing its remote location in the ocean, far away from any civilization. He also emphasizes the boys' lack of contact with the outside world by having them stranded without adults, cut off from communication or rescue. Additionally, the island's dense jungle and treacherous terrain create a sense of isolation and confinement for the boys.
