Whirl Islands

15 Pokémon can be caught at Whirl Islands in Johto — highlighted on the map below.

The Whirl Islands are a small archipelago on Route 41, set in the sea between mainland Johto and Cianwood City and named for the dangerous whirlpools encircling them. Below the surface, a maze of dark caves lets determined explorers move between the four isles. A player holding the Silver Wing and Tidal Bell can find Lugia by entering the northeast island. According to SoulSilver, the islands were once a single landmass, and Olivine City children are warned that misbehaving kids get sent there.
