A pair of twin islands situated in the middle of Route 20. They are connected to each other, but inside is like a maze and it is incredibly difficult to get lost – are those the cries of Pokémon, or a desperate trainer who has wandered astray? Some parts have caved in and underground rivers with fast-flowing water and even whirlpools can prove to be incredibly dangerous. It is inhabited mainly by ice-type Pokémon.
