Iron Island

19 Pokémon can be caught at Iron Island in Sinnoh — highlighted on the map below.

Lying off Sinnoh's western coast, Iron Island can only be reached by boat from Canalave City. Its cave once operated as a thriving ore mine before the deposits ran dry, and the abandoned tunnels now serve as both a wild Pokémon habitat and a training ground. Byron, Riley, and members of the Canalave Gym practice here, as did a young Roark, and Team Galactic Grunts also lurk within the old mine.
